Quiet and nonchalant

You enter the bathroom, closing the door behind you. Teri stands in the shower, fiddling with the temperature. She's let her hair down, her straight blonde locks falling over her dripping breasts.

Entering the shower, you wrap your arms around her, letting the hot water flow over you as you fondle her breasts. She isn't pulling away from you, but she doesn't reciprocate or react either. Unlike April or your family, she's just some girl off the street; you're allowed to use her, of course, but it seems that she isn't very interested in what you're doing. Truth be told, you're turned on by this as much as you are by other sluts like April or your mother and sister actively engaging in sex with you—the idea of a woman finding sex so mundane and commonplace that she doesn't hold any regard for it has always fascinated you, and Teri is playing into that fantasy extremely well right now.

"Okay, beautiful," you say, turning her around and looking her up and down. "Make this the best shower of my life, and then you can get back to your jog." She nods, reaching around behind her back wrapping her hand around your cock. Pointing it downward, she sticks it between her thighs, squeezing them tightly around you.

“I hope you’re fast,” she says, beginning to rock back and forth. “My brothers must be missing me by now. Then again, maybe you’ll be gentler than them.” Shrugging her shoulders, she steps forward, bracing her arms on a wall handle as she sticks her behind out toward you. “Let’s get started.”

Not wasting a moment, you crouch slightly between her legs, thrusting up and into her soaking pussy. Her body tightens slightly as you enter her, but she makes no other movement, remaining silently bent over as you take her from behind. Just because you're allowed to fuck her at your leisure doesn't mean that she has to actually put any effort in on her part. For her, this is just another everyday thing, like breathing and sleeping. Her lack of interest doesn't deter you as you pound her faster and faster, just barely keeping your purchase on the slippery tiles. She’s having the same problem, but just before she falls you grab her hips, lifting her up off the ground. Her body suspended between you and the handle, she hangs limply while you shove your cock in and out of her tight hole.

Feeling your oncoming orgasm, you put her down gently, pulling out of her pussy only to shove yourself between her soft cheeks. Rubbing yourself frantically against her ass, you’re soon cumming, spraying your hot load onto her back where it’s washed away almost immediately. She waits patiently, presenting her ass to you as you coat it with your semen.

"Want another go? Or will that be everything?" she asks politely and courteously, almost as if she were conducting business with you. You're amused by her formality and how she treats being used.
