These stories are a development from the stories by rwxxx13 with the group title "Study bg3-17." He has approved my use of his original characters. Matt and Marsha and Mason by Larry Marion Marsha and Mason followed their third cousin Matthew, better known as Matt into his bedroom. Matt closed the door behind him and locked it. Brother and sister looked at each other. It had been at least five years since they had last seen Matt. He was no longer a scrawny 12 year old, but a very good looking, well built 17 year old senior, a year older than Marsha and two older than Mason. "So grab a chair," Matt said, sitting on his large bed. "I hear everybody's naked at that Jones Lab school you two go to. Not the same a swimming pool. I mean how do you learn when there's a good looking body next to you?" Mason laughed. "It's easier with so many public pools being suit optional. But new students at the beginning of the year have a slight problem. But for the guys it goes away after three or four days. For me, the girls just sort of blend in most of the time." "I thought that myself," Marsha said. "Now it doesn't bother me. It doesn't bother my boy friend. "I'm afraid I'd get swamped," Matt laughed.' "Oh. So you're a real ladies man?" Mason asked. "I guess you could say that. Shit. Guys hit on me, too. It's always been that way. Look, maybe I shouldn't say this, but we last saw each other five summers ago. I was 12. You guys left and four days later I got laid for the first time. That was Betsy. She was nine, but six days later she had a 10 year old friend, Florence. Yep. So two weeks later I had my first girl who actually had boobs. Eve. She was 12 and turned out to be in my 7th grade team." "Sure," Marsha said. "So you still robbing the cradle?" "Nah. Look freshman year my English teacher was just out of college. In fact she was still 20. A stunner. All the guys drooled over her. I mean she looked like a freshman herself. The juniors and seniors went ape. Well, I went in for some help. She helped me all right. The first time she sat on her desk with her skirt hiked up while we did it. After that it was once a week, but from then on in her car or her apartment. "Look, I've even nailed one of mom's best friends. She's still good looking at 41." "Come on, Matt. I mean you're good looking. But you sound like you've made it with ten or so in the last five years," Mason said. "Ten or so? How about over sixty?" Both Mason and Marsha laughed at that but Marsha felt herself getting a bit tingly. He had to be exaggerating - but how much? "Nah. You don't believe me. Look, Mason, under my bed is a thin box. It's not real heavy. Pull it out for me, would you?" "Sure," Mason said as Marsha watched him with a quizzical look on her face. Matt got off his bed, took the box from Mason, laid it at the foot and worked the small combination lock and opened it. Inside was the first of several sheets of paper. Stapled to the paper were underwear, mostly panties or thongs with a few sets of boxer or jockey shorts. The top sheet only had three panties, two thongs, and a pair of boxers. Matt turned the top sheets over to reveal the bottom sheet. Marsha quickly counted twenty pair, 16 panties, two thongs, and one each boxer and jockey. The first five appeared in size to be a little girl's panty. "Marsha, the first pair, the yellow ones with the daisies on it. Lift it up, please. What do you see?" "Uh. A picture of you at 12, I guess and a younger girl. You're both naked. The picture has `Betsy, 9, V, 1' under it." "Okay. See those two pair together, second row, one pink, one pale blue?" Marsha looked and lifted them up. "Amy, Ann, 12, V,V, 9,10." "They're identical twins, Amy and Ann. Amy came first. They're the only identical twins I had the same day. They finally had to do `guess the number closest' to see who screwed me first. She was Ann - I think. "Okay, Not the second sheet, but the third. The black thong top row." "Uh. "Veronica, 20, E, 43. That would be your English teacher?" "Yes. I have to avoid her husband now, but we still seem to make it at least twice a month. Her baby doesn't help." "Oh. I see there's a picture of you and your partner. Did you do that for each first time?" Mason asked. "Mostly. For Veronica, no. She just didn't want it in the classroom. That was taken in her apartment before she met her husband. But the thong was either the one she wore the first time or one just like it. So? Am I full of it? Leaf through them if you want." Marsha looked at him and suddenly saw the raw sexuality in him. He looked her dead in the eye, smiled and winked. She watched him turn to Mason with the same look. Mason turned away, and then swung back again. Marsha slowly smiled at Matt. Matt closed the panty box, and slid it to the floor. He sat back down on the bed and looked at Mason. "So. You ready, Mason?" "I, I don't know." "Sure you are. Marsha do me a favor would you?" "What, Matt?" "Could you come here and unbutton my shirt?" "Uh. Okay. " Marsha smiled again, stepped forward, and quickly unbuttoned Matt's shirt. He didn't have on an undershirt but he flexed his muscles under the open shirt. "Ah. Would you take it off?" Marsha took the shoulders and slid the short sleeve shirt off Matt and let it slip to the bed. He flexed his muscles again. "Thanks, Marsha. Now, could you make way for Mason?" She stepped to the side and back. "Mason. Your sister is so sweet. Have to love her. Now, be a good brother and come and kneel down." Marsha watched as Mason did just that, kneeling directly in front of Mason. She looked at the front of Matt's pants and the bulge in front. He has to have a big cock, she thought. "That's it, Mason. As thoughtful as Marsha. Now, Mason please undo my belt, then ease down my zipper and then undo my waist button. Okay? Marsha. You did a great job with my shirt. So how about taking off your top and bra? Mason, when my pants are undone, you can take off your shirt and we'll all be alike. Marsha began to unbutton her top while watching Mason's back as he obviously began to open up Matt's pants. The top came off so she reached behind and undid her bra, dropping it to the floor in front of her. "Nice Marsha. Nice tits. Real nice. Love those nipples. I want to suck them, Marsha. Suck them like Mason's going to suck my dick first. Ah. Mason. My pants are loose and your shirt is off. Okay. I'm going to rise up just a bit so you can pull my pants and boxers off, Mason. There. Yeah. Off they go. Hey move aside so your sister can see my cock." "That's huge, Marsha. That has to be bigger than Francois'!" "Who's Francois? Some French guy?" "No. From Africa. Paige's other boy friend." "Oh. Interesting. What do you think of sharing, Mason?" "Depends. Francois and I are brothers now. If you want, I share Paige and he shares Simone. But we don't share. We can't share what we don't own." "I may just have to come visit," Matt said with a laugh. "Okay. Brother and sister, let's you two join me and get naked. So stand up Mason and then get back on your knees." Marsha undid her waist button, pulled down the zipper and slid her shorts off, then her plain panties while Mason got out of his jeans and boxers. "My, Mason. That's quite a little boner you have there. I have to think you're looking forward to blowing me. So, if you would drop down and enjoy, my boy." Mason got back down. "That is some cock, Matt. Okay." He licked the bulbous cock head. "By the way, you can cum in my mouth and I swallow. But it's nice to warn me. Okay?" "Sure. And your cock is okay, too. But Marsha, I love that trimmed look. Okay, Mason, let's feel you do your stuff." Marsha only saw her younger brother's head go forward and lower a bit and his hands come up. Then she saw his head moving back and forth. "Yeah, Mason. Feeling good. Marsha could you come up here. Those titties just need some loving. I'm good at that. Yeah. Oh, they are nice. Yeah, bend down just a bit." Marsha did and Matt's tongue began to lick the closest nipple as a hand reached out and went between her thighs. She eased them apart. "Oh, Mason. And I mean this with the highest respect. You are a great cock sucker. Oh, yes! "Uh. Matt, you're doing a number on me. Yeah. I like the way you lick my nipple. And that finger is good." Matt stopped licking the nipple. "Wait until you feel my cock inside your cunt." He laughed and went back to licking the hard nipple. "Okay, Mason. I'm about to cum. Yeah. Get ready. OH, SHIT THAT FEELS GOOD!" Marsha felt Matt stop his licking and fingering as he shot cum into her brother's waiting mouth. When he was obviously finished, he pushed Mason's head away, stood up, and picked Marsha up in his arms to lower her onto the bed. He got in, easing her legs apart and then lowering his mouth to her pussy and clit. In a minute she rolled back and forth on the bed. "Yes," he said. "You're ready for Peter!" With that he eased himself on top of her to guide his cock in. She gasped as some eight inches slid into her tunnel of love. He began to pump her. "Hey, Mason. Come to where I can reach your cock. I have my cock in Marsha's snatch. You might as well have yours for my tongue to play with. Like that idea?" "Sure. And I give warning." "And I swallow." Matt shifted his body and took at least the head of Mason's cock inside his mouth. He continued to pump Marsha. "Matt. You're good," Marsha moaned. "You are." "Nice head, Matt. Feels good," Mason groaned. Matt gave out a moan. Mason had the first climax. Marsha felt her tension mount, from the physical and the mental, and then she had a massive cum, followed by Matt, which brought Marsha to a second one as his cum poured into her. The three wound up in the same bed until Matt said, "Hey, cousins. Why not spend the night here? Plenty of beds. We can share. We even have some virgin toothbrushes. But first, some pics and then let's get dressed and see what parents are doing." So about eleven that night Marsha smiled as the door opened and Matt slid in. "Do you like the picture of the three of us?" he asked as he pulled the covers over them after removing his bathrobe. "Yes. Have you already seen Mason?" "Of course. He's a real sport. I like him. So. It's just us. You want doggie style?" "Sure." She got on her hands and knees. "Where you going?" "Here, slowly," as she felt his cock begin to enter her rose bud. "Mason liked that." She moaned as he continued into her. "I see why you are so popular," she said as she began to rock back and forth. "Wait until morning," he said as he gained speed. "I'm good now," she said. "YES!!" Dear Reader, When I started "After the Experiment" I did not plan to have more than between three to five more stories. Like Topsy, this has grown. With growth came a few errors. For example, we have the line from the Teen Swim Party "... ranging from a bald, flat 11 year old..." when the invitation clearly states that the mandated ages are 12 to 17 so this line should read "... ranging from a bald, flat one who looked 11 . . ." Feel free to point out other errors. If I were to ever find a paper publisher, such errors will be corrected. Thanks.
