I moan, then say, "I thought you were gay?"
"I'm bi, actually," he replies, "Now sush, before I decide to gag you."
He quickly moves from two fingers, to three, to four. It's not long before I'm crying out and shuddering with orgasm. The orgasm is barely over when he removes his hands, drops his trousers, lifts my legs onto his shoulders and buries his penis deep inside my pussy. I lay there, helpless, as his balls repeatedly smack onto my butt, and he soon has me squealing again as I spasm round him in another orgasm. He continues to pound my pussy for another two orasms. Finally, as I spasm and shake yet again, he squirts his seed deep inside my pussy. He pulls out and goes to sit down, but at this David stands up, undresses and lies on the bed beside me.
"You have no idea how much it turns me on, watching Barrowman there fuck you while your tied up." He says.
He then turns me onto my side, buries his own cock in me, and rolls onto his back, so that I'm laying on top of him, impaled on his cock, my hands still tied to the head board. He manages to fuck me very successfully from underneath me, for two orgasms. I am just starting to get back into rhythm, when I freeze because I feel a finger being pushed into my butthole. I have never had anything in my bumhole before, and I'm not sure I like it, but there's little I can do about it. John slowly increases the number of fingers inside my bum, stretching out my hole. All the while David is still fucking me. John then removes his fingers, and pushes his dick into my widened bumhole, stretching it further. John moans in delight at the tightness, I moan a little at the unexpectedness and slight pain of the intrusion, and try to pull away from him, but only succeed in trusting myself further onto David instead, making David groan a little with pleasure. I lay there, perfectly still, feeling uncomfortably full, with one cock buried in my pussy and another cock buried in my arse, my hands still secured above my head.
Once again, I don't have any choice in the matter, with David and John finding the perfect rhythm between them, really going at it as they fuck my pussy and arse together. I yell out with each thrust, initially at the pain of John's intrusion, but very soon that changes as I orgasm again. And again, and again, losing track of how many times I cum. Finally, David spurts his load in my pussy, causing me to shudder again with orgasm, which in turn causes John to shoot his load inside my bumhole. John pulls out fairly soon, disappearing into what turns out to be an en suite bathroom to clean up. I have zero energy, so I just lay there on top of David, with his shrinking willy still inside me. After a long while, David rolls us over, and climbs off me, walking into the bathroom as John walks out of it. I just lay there, my legs wide open, my bits covered in sticky mess, my hands still tied. When David has cleaned himself up, they manage to clean me up and change the sheets without freeing my hands, but they don't cover me up again.
"So how did you like that?" Asks John.
"That was amazing." I reply, "I have never felt anything like it before."
"We're glad you enjoyed it." Says David. They both climb on the bed then, and cuddle into me. John pulls my left leg casually between his, wrapping both of his around it, and rests his hand on my breast. David drapes his right leg on top of my right leg, rests his top hand on John's hand on my breast, and puts his bottom hand between my legs, cupping my pussy. They both fall asleep like this, but my hands are still tied up, so I wonder if they have more activities planned for later.
