Spying on my little sister while she’s in the shower

I crouched behind the bathroom door, breath hitchin’ as the steam rolled out—her skinny body glistened, fingers teasing her panochita slow, moanin’ like she didn’t know I was watchin’. She leaned forward, ass jigglin’, legs spread wide—fuck, she didn’t even know I was here. I bit my lip so hard it bled. She started sentones on the shower wall, back arched, cryin’ out my name like she felt me inside her. I didn’t move. I didn’t breathe. I just watched. And I’ll do it again tomorrow.
