Date: Fri, 17 Jan 2014 14:33:41 +1100 From: Paul Hart Subject: Let's do it Part 4. Let's do it. Part 4 As arranged, Mark arrived, trotting quietly at his heels was a magnificent German Shepherd. With him Mark carried various bottles of lotion - and what looked like a couple of wet suit tops. Setting the lotion to one side he explained the purpose, it seemed that although 'Rastus' the dog had his nails clipped, these could still scratch particularly since he tended to use his front legs to clasp his partner...Marina for example with her breasts hanging down would be particularly vulnerable. We were of course intrigued, Rastus seemed a docile fellow and discussion followed....eventually Marina and I agreed that it should be me to go first. Meanwhile Mark said we needed to check on something - would Marina mind removing her pants for him? She looked bland and said "OK but I thought that the agreement was for AFTER we'd done this...?" Anxiously she was reassured "No, no, this is a safety thing sort of!" and as she settled back, he made his excuses as ever so gently he felt between her thighs....she parted them wider for him as his fingers thrust up...pausing for a second he considered then nodded - reassured. "Yes she'll be able to take him!" Next we were lectured on the business of "Dog knotting" why it happened and it's likely consequences...fascinated Marina and I exchanged glances, meanwhile Mark continued "Now I want you to know that, just in case...for instance Rastus gets stuck too long...I have this anaesthetic spray, I prefer not to use it on him since he'll be actually enjoying the process...yes, he is rather fond of fucking humans...male or female, usually all I have to do is sort of guide him to the right spot...and leave him to it. Now, if you're ready, lets prepare you?" So saying he handed me the jacket, stripping off I put it on and stood there feeling rather exposed....I find that being half naked - from the waist down that is - always makes me feel extra randy and this occasion was no exception for I came erect. Marina giggled and muttered "Can't wait to get it can he?" and she could equally have been referring to the dog...Rastus sensing my arousal immediately sauntered over and began to lick my penis - wow! Mark however called him off, obediently the dog turned and stood back though I could already see something pink and shiny emerge beneath him, "well he's doing the job for me announced" Mark "I usually have to get him ready by hand but here, bend over like so...could you...and I'll apply some of this stuff, just where we need it..." Expert fingers rubbed something around my rim, briefly thrusting inside. Now I was truly aroused and glancing behind I could see, so was Rastus - my God! Not wasting any time, the huge beast mounted me, wrapping paws around to clasp my chest he began jabbing away. Here Mark intervened, grapping the huge slippery penis he guided it to my hole. I gasped, tried to relax, then felt my body being rocked back and forth, the dog was humped up and into me like a piston...God it was going in a long way...the feeling was fantastic, no human lover had ever pleasured me like this, the frenzied energy...well, I'd watched two dogs at it before and been mighty impressed...but this, well he just went on and on...soon I was bucking and whimpering then suddenly, he withdrew and stood beside me panting...quietly Mark explained that this was usually what happened, to just wait a bit and then...suddenly, Rastus mounted me once more this time finding my opening without Mark's help...on and on he went, again he'd take a break only to resume, meanwhile Mark applied some sort of lubricant for soon the obscene sounds emerged - they left no doubt as to what the dog was doing to me...and then I began to cum.....but he kept on....helpless and lost in the enjoyment I released some more....above me the dog panted, beneath him I gasped...this was pure pleasure...almost painful, glancing at Marina I saw her standing wide eyed...I thought I heard her mutter "me next, me next..." and noticed something else too, Mark - he had his hand inside her top and from the movement, he was fondling her breast. I didn't care and then I felt the change in motion....Rastus was unloading...again and again. By now I was in near collapse...I could feel his warm fluids draining down my thighs and then his motion ceased - still clasping me he shoved his penis in as for as he could and then, waited. I felt something swell within me...startled until I remembered, 'Dog Knotting'. Rastus and I were literally tied together, I tried to move but could not, the thing inside felt huge - would I burst? Mark had said not to worry but now I had to wait it out...I felt all wobbly too, how many times had I cum? Marks hands were again busy, he'd helped Marina to undress and now they began to explore her body, she stood there, lips parted and a little smile on her face as she returned my gaze "My God that must feel good, he's HUGE and, and he's all the way up you....yes Mark, just there, that's nice....and her eyes closed as his fingers plunged into her.....he can't move yet can he?" Mark answered her "No, not yet, he'll be exhausted too, on the other hand Rastus will be ready to go again once he gets out...would you like me to get you ready know...we can do it while he watches if you like?" Marina's eyes widened in delicious horror "You mean, you want to fuck me while he watches - helpless? No, let's fool around first, get your stuff off too" I watched as Mark obliged and stood beside me naked....Marina knelt before him, taking his penis in her sweet mouth, she began to suck until "Here, my jaw's starting to ache...let's do it now shall we...make sure he can see though". Mark had her bent backward, smooth flat tummy and the swell of her mound exposed, deliberately he sauntered between her legs...and I saw his buttocks thrust into her...then they began to rise and fall, next her arms appeared to reach behind him, fingers digging into his back. When next he spoke it was with an husky voice....oh God, she's lovely, Rastus is going to be one very lucky dog....as if recognising his name, the dog reared up and sideways, all four paws now on the ground, inside me the knot twisted, something happened with my prostate and I began to shudder helplessly while our arses remained joined. I nearly fainted. Meanwhile other sounds were emerging, Mark was certainly enjoying Marina, that was obvious, his gasps and her little moans told the story...meanwhile I waited, weak and with senses overwhelmed....Mark was finishing off in Marina and I saw her arms withdrawfrom clasping round his waist..panting slightly and wet with his sperm, she leaned back, Mark announced "Timing's good....Rastus should be ready soon" and sure enough, the pressure was easing, in another minute I pulled forward...to feel something slipping from my insides. I fell flat and lay there briefly "Mark...don't tell me, he'll be ready for her now? I can't believe it...and I'm literally swimming in his stuff, he's used me like a bitch...and he's ready again you reckon?" Mark assured me all would be well, adding that as far as he was concerned, the remainder of our contract had been discharged, though of course if either of us felt like adding a 'tip' at some stage...then that would be quite another matter? Hmmm, now there was food for thought!
