Date: Tue, 25 Jul 2017 18:12:20 -0400 From: steamgene@cox.net Subject: After the Experiment: Mason and Grace Is there any way to go back to the first five stories and put this at the end? Mason and Grace - After the Experiment - (A Continuation of Study-bg3-17 by rwxxx13) by Larry Marian Author's note. This story is a development from the stories by rwxxx13 with the group title "Study bg3-17." He has approved my continuation with his characters as individuals. Will they meet again? We will see. * * * * * * * * * * * * Mason walked out of the boy's shower room wearing an old shirt, his drying swim trunks, and sandals so he could pedal his bike home. Looking at the bike rack he saw only one other bike - a multi speed street bike for girls. The the door to the girl's shower room opened and out stepped Grace. His heart almost skipped a beat. Red headed, pony tailed, green eyed Grace who lived three doors down from him and had the same teacher as him all through elementary school and was in the same team with him now that they were in middle school. He could feel his tongue begin to twist in knots - just like it had always done for years. "Uh - hi, Grace," he said softly, trying to keep his voice calm and steady. "Mason - I saw you were back and at practice. I'll tell you, I was sorta worried about where you were. Nobody had a clue. Like you was kidnapped by zombies or Klingons or something." Mason chocked out a laugh. "So where were you. And don't tell me that Frank and Joe Hardy needed your help. " With this came a crystal clear laugh from her. He noticed she wore a modest two piece, not a bikini, and not a one piece racing suit, but one that fully covered her but had ties on the sides of the bottom and also ties at the neck and back for her top. Like him, she had on an old shirt and sandals. "So where were you, Mason?" She laughed again. "Girls want to know, after all." He gave a timid smile. "Uh. It's hard to explain, Grace. In fact, there's a lot I still don't understand. But some sort of experiment." How could he tell Grace, of all girls, about living with two girls, his age, all three of them naked as jay birds, sleeping in the same bed, showering together, for at least a month? She'd probably slap him or something. "So were you in a house? Some college or something?" "I don't know. I can say that it was all white - or mostly white. There was a kitchen/dining room, a bathroom, a sort of living room/den, and a bed room. It was always nice - not too hot, not too cold. " Grace looked at him closely, "Mason. Would you tell me more about this? I think something has changed with you. Want to come to my house and tell me more?" Tell her about two nude girls? The porn movies? What they did together? What would she think?!? "Uh. Some of this stuff is sorta strange, Grace. You sure you want to hear about it?" He watched her bite her lip. "You know, we've swum together for seven years now, Mason. I think you're a pretty cool boy, So, yeah, Let me know about it. " Mason's heart went into overdrive. Grace. Interested in him. Grace. Pretty red head Grace. Grace. "Okay. But you can't tell nobody." And what would Paige say to "nobody"? "So do you want to hear my story now?" "Yes. Let's go to my house now." With that Grace hopped on her bike and pushed off. "Come on, Mason. Let's go! So Mason put his foot on the pedal, gave two pushes with his free leg and swung over to find his other pedal and raced after her, watching the red pony tail bob from right to left as her legs worked the pedals. She was not going slow so it was mere minutes until she sharply turned into the drive of the brick rancher he had never entered. She braked at the garage door and he did, too. "Let's just leave our bikes here, okay?" she said and he nodded, then followed her to the side door which they entered into the kitchen, then down a short hall and into what had to be her bedroom. He had expected maybe pictures of rock musicians or film stars or such, but what he saw were swimmers - Olympic, marathon, college, high school, a wide variety. What shocked him was a small picture of himself on the starting block last year - had to be when he helped win the boy's team medley at the championship. He gulped. "This is my room," she said and smiled. He glanced around. "It's nice," and he surveyed the student desk, the dresser, the bed - a full bed, not a cot, the rug, the curtains, all very neat but nice. There were still a couple of dolls and a stuffed rabbit - like some of the things he still had, but in the closet most of the time. "You want to sit on the bed and tell me about what you did?" she asked, sitting down as though showing him what she wanted him to do. "Okay," he said. "Some of this will be strange. It sure was at first." He sat down next to her and turned to look at those green eyes. "The first thing I knew was I woke up on a really big bed with two girls looking down at me. They seemed as puzzled as I was." "So you were on a bed and they were standing up? So were they in pjs or regular clothes or what? I guess you were under the covers? Why was the bed so big?" Her questions came out as a torrent. "Uh. How much do you really want to know, Grace? Like I said, at first it was really weird. Uh, the girls were Jenna, who was the taller and older and Paige, who was shorter and younger. Paige turned out to be real smart. But no, the bed didn't have anything other than three large pillows - no sheets, no blankets." "Wow. So I guess you were in pjs?" He paused. What to say? Well, she wanted to know. "Uh. No. None of us were. In fact, all three of us were totally naked. " Mason saw the surprise, the shock on her face. "Really?? You were lying in a bed and there were two girls looking at you and all three of you were naked?" She paused. "So how old were the girls?" "We were all 12 in the beginning, Jenna actually turned 13 just before it ended. Paige was younger than me by a few months." He grinned. "At first we tried to hide ourselves - you know. But Paige convinced us that was stupid and we were just nude." "Weird," Grace said. "So why were you there?" "Well, we got a folder in the beginning and then from time to time some announcements and our scores. It seems our parents were in some sort of money hot water to some company and the agreed that we could be subjects to an experiment. They know nothing of the experiment..."? "Well, I bet your folks didn't know you were naked with two naked girls!" Grace exploded. "They don't. We were told to say nothing to our parents and not go into detail with any friend and to not spread it around. I'm not going to go out on the diving board and say, "Hey, team! Guess what! I spent a month or more with two girls and we were all naked all the time!" He grinned. "Actually, we did get napkins for when we ate. But that was it. I guess they knew how uncomfortable it would be if we dropped some hot food on our lap!" Grace smiled. "So what did you eat? School cafeteria junk?" "No. We almost never got the same thing as each other. It was like they knew what we each liked and maybe for breakfast Paige would get oatmeal and some fruit while Jenna would get a bagel sandwich and coffee and I'd get a cheese omelet and bacon. We all got juice, but it wouldn't be the same juice. Good stuff." "Wow." She smiled at him. "Do you want to talk about this, Mason? It does seem a bit personal - like with you and two girls being naked together for a month or more," "I guess it's okay, Grace. And apparently it help out all our folks and we got money for college." "Wow. Great." She smiled at him again. "So what did you do?" She looked down at the floor. "I mean read, watch tv, games, that sort of things." `Uh. Grace, I've always thought you were a neat girl. I don't want to make you mad at me just when we start to talk. We were subjects of an experiment and they sorta pushed us in one direction. We had to do things to get out of it. Do you want to know more?" He looked down at the floor, avoiding her eyes, "I've always thought you were a nice boy, Mason, Maybe you had to do what you had to do, whether you liked it or not. I mean, just to get out of the experiment." He felt her against her and suddenly, not thinking, put his arm around her. She turned and smiled at him again. It looked like the signal sent to him so often by Paige and Jenna as he turned to face her, face to face and then kissed her. She didn't back off. Rather he felt an arm on his back, pulling him closer. Without thinking, his tongue began to probe her lips and they opened for it, so it slipped into her warm mouth to feel the tip of hers. He felt his cock grow rock hard. Would he replace his tongue with his prick soon? The kiss lasted and lasted so his hand went down to the bow knot on the straps of her top. It came loose without protest as he slipped his hand under the fabric and felt her bare boob, crept up the slope to a hard nipple. She broke the kiss. "No boy has ever done this, Mason. You're the first." Lips barely touching, he said, "I'm glad. Is it okay." "Wonderful," she breathed. With that he fingered the top bow and it came loose and the top slid to her lap as they slowly lay down on her bed. He glanced at her bare breasts, smaller than Jenna's, larger than Paige's, with a very pale and small nipple area, making the erect nipple stand out. He moved his head and kissed her right nipple, then the left. "Oh," she said,. "That feels great." I've never undressed a girl, Mason thought as they kissed and he caressed her boobs for a few minutes, then his hand went again for a bow, one on her bottom. Here she would stop him, he was sure. But he was wrong. One bow came loose, then the other with a bit of a struggle, and he pushed the top onto the bed and lowered the front of the bottom and touched her. As he did, she opened her thighs for his inspection. His finger found her vertical lips, parted them, then slowly entered an already hot and wet, not damp, pussy. "You know what oral sex is, Grace? I think you will like it. " "Okay. It seems good now," she responded and he slid down her, kissing his way to her breasts, her stomach, her belly button, down until he saw the light red still thin patch of pubic hair and then he kissed her, parted her lips and let his tongue probe the tunnel and then find her clit so he could suck on it. "Oh, God!" she said. "Oh. Mason. That's wonderful. Oh!" Grace thrust her hips up as though she were trying to swallow his face with her young, virgin cunt and hot liquid filled his mouth. "OH!!!" Then they dropped back to the bed. "I can't believe that was so good, Mason. Kiss me!" So he kissed his way back up to her horizontal lips, not forgetting both nipples and kissed her, almost surprised as her tongue entered his mouth first. It was an awkward French kiss on her part, but he figured it was, if not her first, one of her first. It flashed through is mind that just about this time yesterday he had his best friend Larry's dick in his mouth while he sucked him off. Not anything to tell Grace. She broke the kiss. "I guess I should do the same for you," she said softly. "If you want to," Mason responded. "I don't really know how," she said. "Just treat it like a lollipop, but cover your teeth with your lips. I'll warn you before I cum." "What did the girls - what are their names - do when you did?" "Uh. They kept on doing it until I came. Then they swallowed it. They both said it didn't have a bad taste. Sort of sweet but sort of salty. Sometimes more sweet than salty, sometimes the other way around." Sort of like Larry's, he thought. "And they are Paige, who really loved to blow me and Jenna who really preferred to screw." "You must have love it. So I guess you lie on your back?" "Yeah," which he did, then raised his hips and began to tug his tight swim trunks down, from which is hard cock sprung on release. "It's big!" Grace gasped. Mason grinned and got his trunks down to his knees. With that Grace grabbed them and pulled them completely off. "If I'm naked; you're naked," she said. She reached out tenatively and touched it. "Gee. It's really hard." Then she ran a finger over the glistening rounded red head. "But that' so soft." She looked at him. "So what do I do?" "Take it in your hand and lower your mouth on it. Close your mouth but not real tight and then just go up and down." This was no time to teach her advanced sucking, for sure. So she took his hard cock in her right hand and brought her face to it, paused for a bit and then took the head in, closing it so he felt her lips on his shaft, then began to move down. "Take it easy. Go up, then down further. Go further each time until you can't any more." She did, slowly at first, then faster and faster until her red pony tail began to bob as it did when she rode her bike to her house. He reached out and rubbed her bare back, then slipped it under to feel her breast and the rock hard nipple. "That's nice, Grace. Nice. You are doing fine. Yes. Nice." Again, yesterday and Larry flashed through his mind. He'd sucked Larry first, like was normal with them after six session, then Larry had blown him. Then Larry suggested trying 69, and they did, lying on the bed, head to cock, cock to head. What would Grace think? He felt his cum coming. Yesterday he couldn't warn Larry like Larry couldn't warn him, but he could Grace. "Grace. I'm about to. If you want to stop, you need to..." But she didn't and he came hard and she took it. The first blast, the second, the fourth, the dribble, then raised her face and smiled, a bit of cum on the right corner of her lips. He reached up and kissed her hard and deep to taste the his hot cum that had shot into her mouth. Wow. "Oh, God," he said. "Is it okay?" "Yes, Mason. It's fine. I sorta can't believe it. But it's fine. Fine." She rolled over onto her back. "So, now we do it?" Mason chuckled. "Give me a minute or so. But I do want to if you do. Don't worry. They did something to us. The girls can't get pregnant for at least two years and I can't get a girl pregnant for at least four. They told us that. I think they told the truth. I found a little patch. You don't want to know where it is. " "Oh." Grace sat up. "It's so small now." "That won't last Grace. With you right there all beautiful and nude, I'll be hard again real soon. " He chuckled. "For the first few days in the white rooms I stayed hard all the time. At first Jenna wanted to know if I could do something about it. Paige thought it was very interesting." He felt the familiar stirring. Yes, the beautiful nude Grace did the job. "Oh, my! That's weird." She giggled. "It's like a balloon!" "I guess so. Uh, Grace, you're a virgin, right?" "Right now I am," she said softly. "I guess that's gonna change." "Yeah. Look, why don't you get an old towel. We saw a film. There may be some blood." He paused. "They don't call it a cherry for nothing," and gave a weak grin. "Yeah," she said and rose from the bed. "Be right back," she said over her shoulder. He looked over at Grace's desk and saw her bra draped over the desk chair's back. He grinned, got up and picked it up, saw a tag hanging from the end of one strap and read "30B" on it. So that's her size, he thought, put it back where it had been and went back to her bed and sat down. He glanced at the two swim suits on the floor. Grace entered the room again with a large, but a bit ragged bath towel. "I guess I just spread this on the bed and lie down?" "Well, fold it a bit and put it on the bed. Look, one of the films we saw - it would be better if I lay down and then you just kneel on top of me and take your time. They say that's the best way for the girl's first time. And it's fun. " "Okay. I guess so. If you say so." So Grace folded the towel and Mason lay down on his back just like the first time he and Paige had given each other their virginity except this time there was a towel under his butt. Grace straddled him, her knees at his waist and her pussy poised to plunge down on his pecker. "Guide me with your hand," Mason coached and he felt her hand grasp his hard cock and set it between her pussy lips. She paused again and then slowly sank down until he could feel the head begin to enter her. She stopped, looked down at him, and smiled. His hands came to her waist to guide and support her and then she pushed down. "Ouch," she cried and then, "Oh," as she slid down, pushing his cock deep into her pussy. "Oh, Mason." "Grace. Yes. Now, easy, start going up and down. Start slow." She did, smiling at him, her pony tail beginning to swing again as she rocked up and down. "Oh," Mason groaned and began to match her, going up as she went down and down when she went up, each time his cock driving deeper into her wet warmth until her pussy touched his ball sack on each stroke. "Yes, Grace. Yes." "I think,,,, I think,,,,, I think,,,,, oh! yes, I'm gonna cum again. I am, OH!!!"and she shuddered, falling down, his cock still deep in her. As she kissed her once shunned neighbor, he came, too, another heavy cum spurting into her. Then he felt warm wetness spread on his crotch as she began to rise up off him. She looked down. "Mason!!" Her hands flew to her face. "There's blood all over you! And on me!" Mason rose up. "Uh. Yeah. Paige and Jenna said they lost theirs horseback riding. What are we going to do?" "You like there. I'm going to get a wash cloth. The shower is big. My older sister and I showered together until last year. We can rinse off there. But we gotta hurry." "Grace. Good idea. Uh, I think I love you!" "I know I love you. Be right back." Mason watched her walk out of the room, while he sat up, keeping the towel under him. Jenna and Paige and Larry were great. But why did I have to not speak to Grace for so many years? They arrived at morning swim practice the next day together, dropped their bikes and entered the pool gate hand in hand. The boy's assistant coach saw them, nudged the swimmer beside him, and soon the entire team looked at them. Mason and Grace holding hands. The world must be coming to an end.

You're the first." Lips barely touching, he said, "I'm glad. Is it okay." "Wonderful," she breathed. With that he fingered the top bow and it came loose and the top slid to her lap as they slowly lay down on her bed. He glanced at her bare breasts, smaller than Jenna's, larger than Paige's, with a very pale and small nipple area, making the erect nipple stand out. He moved his head and kissed her right nipple, then the left. "Oh," she said,. "That feels great." I've never undressed a girl, Mason thought as they kissed and he caressed her boobs for a few minutes, then his hand went again for a bow, one on her bottom. Here she would stop him, he was sure.

"Oh, God!" she said. "Oh. Mason. That's wonderful. Oh!" Grace thrust her hips up as though she were trying to swallow his face with her young, virgin cunt and hot liquid filled his mouth. "OH!!!" Then they dropped back to the bed. "I can't believe that was so good, Mason. Kiss me!" So he kissed his way back up to her horizontal lips, not forgetting both nipples and kissed her, almost surprised as her tongue entered his mouth first. It was an awkward French kiss on her part, but he figured it was, if not her first, one of her first. It flashed through is mind that just about this time yesterday he had his best friend Larry's dick in his mouth while he sucked him off. Not anything to tell Grace. She broke the kiss. "I guess I should do the same for you," she said softly. "If you want to," Mason responded. "I don't really know how," she said. "Just treat it like a lollipop, but cover your teeth with your lips. I'll warn you before I cum." "What did the girls - what are their names - do when you did?" "Uh. They kept on doing it until I came. Then they swallowed it. They both said it didn't have a bad taste. Sort of sweet but sort of salty. Sometimes more sweet than salty, sometimes the other way around." Sort of like Larry's, he thought. "And they are Paige, who really loved to blow me and Jenna who really preferred to screw." "You must have love it. So I guess you lie on your back?" "Yeah," which he did, then raised his hips and began to tug his tight swim trunks down, from which is hard cock sprung on release. "It's big!" Grace gasped. Mason grinned and got his trunks down to his knees. With that Grace grabbed them and pulled them completely off. "If I'm naked; you're naked," she said. She reached out tenatively and touched it. "Gee. It's really hard." Then she ran a finger over the glistening rounded red head. "But that' so soft." She looked at him. "So what do I do?" "Take it in your hand and lower your mouth on it. Close your mouth but not real tight and then just go up and down." This was no time to teach her advanced sucking, for sure. So she took his hard cock in her right hand and brought her face to it, paused for a bit and then took the head in, closing it so he felt her lips on his shaft, then began to move down. "Take it easy. Go up, then down further. Go further each time until you can't any more." She did, slowly at first, then faster and faster until her red pony tail began to bob as it did when she rode her bike to her house. He reached out and rubbed her bare back, then slipped it under to feel her breast and the rock hard nipple. "That's nice, Grace. Nice. You are doing fine. Yes. Nice." Again, yesterday and Larry flashed through his mind. He'd sucked Larry first, like was normal with them after six session, then Larry had blown him. Then Larry suggested trying 69, and they did, lying on the bed, head to cock, cock to head. What would Grace think? He felt his cum coming. Yesterday he couldn't warn Larry like Larry couldn't warn him, but he could Grace. "Grace. I'm about to. If you want to stop, you need to..." But she didn't and he came hard and she took it. The first blast, the second, the fourth, the dribble, then raised her face and smiled, a bit of cum on the right corner of her lips. He reached up and kissed her hard and deep to taste the his hot cum that had shot into her mouth. Wow. "Oh, God," he said. "Is it okay?" "Yes, Mason. It's fine. I sorta can't believe it. But it's fine. Fine." She rolled over onto her back. "So, now we do it?" Mason chuckled. "Give me a minute or so. But I do want to if you do. Don't worry. They did something to us. The girls can't get pregnant for at least two years and I can't get a girl pregnant for at least four. They told us that. I think they told the truth. I found a little patch. You don't want to know where it is. " "Oh." Grace sat up. "It's so small now." "That won't last Grace. With you right there all beautiful and nude, I'll be hard again real soon. " He chuckled. "For the first few days in the white rooms I stayed hard all the time. At first Jenna wanted to know if I could do something about it. Paige thought it was very interesting." He felt the familiar stirring. Yes, the beautiful nude Grace did the job. "Oh, my! That's weird." She giggled. "It's like a balloon!" "I guess so. Uh, Grace, you're a virgin, right?" "Right now I am," she said softly. "I guess that's gonna change." "Yeah. Look, why don't you get an old towel. We saw a film. There may be some blood." He paused. "They don't call it a cherry for nothing," and gave a weak grin. "Yeah," she said and rose from the bed. "Be right back," she said over her shoulder. He looked over at Grace's desk and saw her bra draped over the desk chair's back. He grinned, got up and picked it up, saw a tag hanging from the end of one strap and read "30B" on it. So that's her size, he thought, put it back where it had been and went back to her bed and sat down. He glanced at the two swim suits on the floor. Grace entered the room again with a large, but a bit ragged bath towel. "I guess I just spread this on the bed and lie down?" "Well, fold it a bit and put it on the bed. Look, one of the films we saw - it would be better if I lay down and then you just kneel on top of me and take your time. They say that's the best way for the girl's first time. And it's fun. " "Okay. I guess so. If you say so." So Grace folded the towel and Mason lay down on his back just like the first time he and Paige had given each other their virginity except this time there was a towel under his butt. Grace straddled him, her knees at his waist and her pussy poised to plunge down on his pecker. "Guide me with your hand," Mason coached and he felt her hand grasp his hard cock and set it between her pussy lips. She paused again and then slowly sank down until he could feel the head begin to enter her. She stopped, looked down at him, and smiled. His hands came to her waist to guide and support her and then she pushed down. "Ouch," she cried and then, "Oh," as she slid down, pushing his cock deep into her pussy. "Oh, Mason." "Grace. Yes. Now, easy, start going up and down. Start slow." She did, smiling at him, her pony tail beginning to swing again as she rocked up and down. "Oh," Mason groaned and began to match her, going up as she went down and down when she went up, each time his cock driving deeper into her wet warmth until her pussy touched his ball sack on each stroke. "Yes, Grace. Yes." "I think,,,, I think,,,,, I think,,,,, oh! yes, I'm gonna cum again. I am, OH!!!"and she shuddered, falling down, his cock still deep in her. As she kissed her once shunned neighbor, he came, too, another heavy cum spurting into her. Then he felt warm wetness spread on his crotch as she began to rise up off him. She looked down. "Mason!!" Her hands flew to her face. "There's blood all over you! And on me!" Mason rose up. "Uh. Yeah. Paige and Jenna said they lost theirs horseback riding. What are we going to do?" "You like there. I'm going to get a wash cloth. The shower is big. My older sister and I showered together until last year. We can rinse off there. But we gotta hurry." "Grace. Good idea. Uh, I think I love you!" "I know I love you. Be right back." Mason watched her walk out of the room, while he sat up, keeping the towel under him. Jenna and Paige and Larry were great. But why did I have to not speak to Grace for so many years? They arrived at morning swim practice the next day together, dropped their bikes and entered the pool gate hand in hand. The boy's assistant coach saw them, nudged the swimmer beside him, and soon the entire team looked at them. Mason and Grace holding hands. The world must be coming to an end.
