Very.

Who would have thought that the sound of a bottle being snapped open could be so sexy? You certainly wouldn't have, before, but you are so worked up at this point that your body reacts to every little step towards what's about to happen with eager anticipation. Anticipation which is soon rewarded as copious amounts of cold, viscous lube are poured along your crack. You let out a small yelp at the cold sensation, but the fire raging within you warms it up pretty quickly. Sam's hands quickly get to work spreading the stuff out. Not just in and around your hole, but all over your ass. "Uh, Sam?" In the corner of your eye you see the bottle flying discarded across the room, and then Sam starts massaging your ass. "What? With an ass like this in front of me, you didn't think I was going to use my hands, did you?"

Sam lays his cock along the length of your ass and pushes it as deep as possible, then starts slowly humping you. "Thaaat's it. You'd better get it nice and slick. Or don't, if you prefer it that way." Your ass, while nothing to scoff at, thank you very much, is not nearly large enough to envelop his entire cock like this. "Come on, Sam. I swear, if you cum on my back before even having the decency to get me off, I'll cut you." He laughs. "Oh, don't you worry. I'll make sure you're well and truly stuffed." With that trunk of his, you don't doubt it. Briefly, Sam looms over you to get a new angle for his hands-free lube application, then he takes up his position right behind you. "You ready?" "Fuck me, already!"

That's surely enough of a hint for any man to get. And indeed, you soon feel a spongy warmth press against your thoroughly lubed hole. A worryingly large spongy warmth, that is. Oh, fuck, this is going to hurt. Despite the lube, when Sam slowly pushes into you, it does indeed hurt, though not as much as you'd feared. "Fuuuuck, Cindy! You sure you've done this before? So fucking tight..." You don't even dignify that with a response. Though in fairness, the pile that's now being driven inch by inch into your ass is definitely among the largest things ever to go in there. And it's been a fair while, too. With every push forward, you find yourself thinking "Surely that's it?" Only to gasp out loud as even more of it enters you. Finally, mercifully, you feel his hips make contact. He's so fucking deep!

Sam pauses for a moment. "You ok?" "Fuck! Yeah! Fine! Fuck!" Rather than immediately hammering you, which might have been a bit much even for you, he at first only gyrates his hips, which stirs you on multiple levels. "Are you sure?" "Yes, I'm sure! Get on with it!" Like a snake, Sam snaps forward. He pushes you down, seizes your wrists and pulls your arms apart while also pushing your knees wide with his own. Now that you are spread-eagle on the bed, Sam's cock somehow reaches even deeper into you. Then he begins to move. In this position, he can barely pull more than half his cock out of you before sinking it back in, but that's plenty to make you scream. You bury your face in the mattress as he thrusts faster and faster. You can not so much as twitch a muscle held down like this, and somehow you find that intensely arousing. You've never been much of a sub before, but perhaps you should give it a try?

"Fuck, Sam! Fuck me!" He doesn't speak, he just leans down and growls. As he pounds you mercilessly, all capacity for speech escapes you. Not that he needs any encouragement. How long can he even keep this up? Sure, he's athletic, but still...

Now that the smouldering embers of your lust are being rather thoroughly stoked, the fire is soon reaching new heights. You cum, hard. Perhaps Sam notices you squirming even more, perhaps he doesn't. The result is the same: he just keeps going. And going. As minutes pass, repeated orgasms send you into a near delirium. You just barely notice when Sam speaks. "Fuck, I'm going to cum! I own you, bitch! You are mine!" He slams himself all the way into you as you feel his cock twitch deep inside. He pulls out, then thrusts forward again at the second twitch. You can't even keep count anymore. Was it six, in the end? Seven? All you know is that it ended with him laying on top of you, both of desperately panting for breath, a heaving mass of sweat and other bodily fluids.

Sam recovers faster than you do and pushes himself up, keeping his softening dick inside. "Damn, Cindy, " he says, bushing some hair out of your scarlet face, "We should do that again some time." "Uh-huh..." He sits up on his knees, letting all but the tip of his cock slide out of you. When he does pull it out completely, something else takes its place immediately. "There. Can't have you making a mess." He must have grabbed that butt plug. Wasn't that a little bigger, before? You feel a little woozy, and can't find it in you to object to what Sam is doing. His task complete, he lies down next to you and strokes your hair. He is whispering things into your ear, but you can't really make out the words. Exhausted, you fall into a deep sleep.
