Look in at her

Nick gently cracked open the door, and watched through the gap between the wall and the shower curtain. She hadn't bothered to close it all the way, and he wondered if she had been thinking about being watched. Jessie reached back, and pressed a finger against her asshole. Nick drew a quick breath, and felt himself grow hard again. He placed his hand on his cock, and held his breath. A few seconds passed, and then, before his eyes, she pushed her finger inside of her ass, and he stroked his dick.

Jessie sighed. Why did it feel so fucking good? It was embarrassing, shameful even, and she had a faint prickle on the back of her neck, as if she was being watched. She slipped two fingers inside of her pussy. It didn't feel the same with her finger, more narrow than any of Nick's. A second finger would be bigger, though not as big as his dick.

She tried it, and found her backdoor greedily accepted the second finger. She quickly fell into a rhythm, alternating the thrusts into her pussy and ass. Her knees felt weak, and she leaned forward, pressing her cheek against the cool tiles as warm water fell onto her butt. She felt as though she could hear the sound of rhythmic skin on skin, imagining that she could hear someone masturbating behind her, by the door, but that was impossible.

Nick was about to cum. Without a doubt, this was the hottest thing he'd ever seen. He realized that if he came here, he'd make a mess, and she'd probably notice. He could just go in there, and cum on her ass. Or maybe he could just fuck her again, even potentially take that anal virginity she seemed to be begging to lose. Or he could just cum, and then sneak out and pretend he'd been gone the whole time.
