Alaina rides

"I want it in me," Alaina breathes, pulling herself out from under you.

"What?" you ask. You know what she means; you want to hear her say it.

She presses her forehead against yours. "I want your dick," she says. "I want to ride your dick." Your neighbor from across the hall climbs on top of you, supporting herself on her knees, and pulls your pants down to your ankles. Your dick is already hard, pushing against the fabric of your boxers and making a furious tent. Alaina palms the tip of it, feeling the wet mark on your underwear that your pre-cum has made. "Warm," she says. "I like it."

"It likes you too," you say.

"I'm glad." Alaina reaches behind her back and undoes the clasp on her bra, throwing it back toward the door with her dress, her panties, and her heels. You've never seen her breasts before this moment. Like the rest of her toned, athletic body, they're perfect. Perfect perky teardrops. Perfect pinkish nipples. Perfect bounce as Alaina sits lightly on your knees. "You're so hot," she says. "Fuck."

You actually find yourself blushing a little. "Uh, thank you," you say.

Alaina laughs. "Don't sound so surprised. I wouldn't have let you eat me out if I didn't think you were cute."

"I said thank you," you say. You grab her by the hips and pull her closer to where your tool is poking through the gap in your boxers. "Now. I think you said something about wanting to ride my dick?"

"You know, I think I did," she says. "So why don't I do that?" She pulls your boxers off of your ass and down to your knees. The carpet feels strange rubbing against your bare ass cheeks, but considering the situation, you're hardly going to complain.

She pushes your torso onto the floor as she slowly lowers her pussy onto your dick. The warmth is unreal. The look on her face, unreal. The pleasure radiating from your genitals and through your whole body, just as unreal.

Even better is when she starts to bounce. Her mouth is open, her eyes are closed. The tips of her fingers are resting on your chest. You feel her ass against your thighs as she rides you. At first she's quiet. She doesn't make a sound, but she does move every time you thrust up into her. Minutes pass, completely quiet. You begin to make faint grunting sounds, and as if in response, Alaina begins to moan. Like your grunts, it's quiet, but more constant, like a flat bar of noise filling the stale air of Dr. Porter's office. Both your grunts and her moans climb in volume as she bounces on your dick, increasing slowly in intensity to match your noises. She's sweating, her brown hair falling over her face as her head lolls back in pleasure. She rocks, pressing her pussy against your pelvis, grinding in amazing circles. You have to tense every muscle in your body to keep from cumming inside her right then and there.

"Oh my God," Alaina groans. "It's so good!"

You can feel yourself mounting toward orgasm. You try to stop yourself, to preserve the sex, to keep fucking her, but it quickly becomes apparent that holding off much longer is completely impossible. You're going to blow, that's just a fact. And then...
