Follow her into the shower.

Rebecca appears startled by your presence, covering her naked form with a towel.

“W-what are you doing?” she asks, confused.

“What do you think I’m doing?” you say, ripping the towel away from her body. “Get in the fucking shower.”

You push her into the shower and begin to shed your clothes, tossing them into a pile in the corner before you’re standing completely nude in front of her, your dick already standing at attention. You turn on the taps until steam starts to fill the room from the hot water spraying on top of the two of you. You turn her around and press her hands and tits up against the glass door of the shower, holding her arms above her head by her wrists.

"What are you doing?" she asks again, "S-stop!"

She struggles against you, but can barely fight against your strength. She begins to shiver at the coldness of the glass, contrasting with the scalding hot water spraying her body from behind. You force her legs open with your knees, and she grimaces as you slide your cock into her pussy. It’s incredibly tight, even more so as she clenches as you push your way in. You start fucking her, slowly at first, but increasing in speed once she’s all warmed up.

“Stop..." she says through gritted teeth, her face pressed up against the glass. "Why are you doing this?”

“Your lips say one thing, but your body says another,” you laugh, noticing as her ass and hips start rhythmically grinding against you as you fuck her from behind.

Your cock starts gliding effortlessly in and out of her as she gets progressively wetter and wetter and her breaths get deeper and deeper. Try as she might, she can't help but gurgle some pleasured moans as you smash her tits against the glass, making sure that your cock hits every single sweet spot inside of her pussy. You reach up and pull the shower head off its holder, maneuvering it around her hips to the front of her and firing the stream of hot water in between her legs. The pressure of the pulsating surge of water spraying against her groin begins to set off her orgasm, as she presses her hand up against the glass for balance. You start to fuck her faster, as her moans get louder and louder, despite her best efforts, echoing off the tiled walls of the bathroom.

"No..." she groans hoarsely, subconsciously rubbing her groin against the shower head. "Stop... I don't want to..."

"Ah... Ah... AHHH!!"

You flick the shower head back and forth across her clit as she cums violently, collapsing back on top of you and throwing her arm over your shoulder for support. You wrap your arm around her torso, practically lifting her off the ground each time you thrust yourself inside of her, as she bites the back of her hand to try and stifle her cries. As her orgasm begins to subside, you push her onto her knees and turn her around, affixing the shower head back onto its holder.
