"Do it."

"Please fuck me," Alex says. "I need it."

Nathan grins and pushes into Alex. Each inch feels like it'll split him apart. When he's finally all the way in, he pauses for a moment, then pulls back. Almost instantly, Alex feels a yearning for the fullness that Nathan provided. Fortunately, he didn't have to wait long for it to return. Nathan starts thrusting into Alex over and over again, each thrust accompanied by a moan and the sound of his balls slapping against her ass cheeks.

"Oh fuck, it's so good," Alex says, hands flying up to play with her tits, which jiggle with each thrust, through the fabric of her shirt. The pleasure that she was able to pull from them is added to the sensation of being filled and brings her to a screaming orgasm almost instantly. Her back arches, as much as it can in the strange position she finds herself in, and her vision goes dark. It seems to last for ages, and when she comes back she realizes that she's still moaning with each thrust. "Oh God..." she whimpers.

"You like that, slut?" Nathan asks. "You like my dick inside you? Filling you up?"

"Oh fuck..." Alex says, her eyes squeezing shut. "I do. Please keep fucking me, never stop."

"You got it, babe," Nathan says. He keeps plowing her, and she keeps trying to milk as much pleasure from the experience as she can. Her hands move from her tits to her clit and back over and over. She cums again and again, her whole body quivering.

After her 6th orgasm, Nathan grunts. "I'm gonna nut..." he says,

Alex moans, her pussy squeezing Nathan's dick as she hears the words. She wants it inside her and she wants him to pull out, but she can't verbalize either request.
