Stumbling upon SweetieSluty in the gym, I found her yoga pants hiding nothing but her eager, tight ass. My cock, already stiff from her big boobs bouncing in her sports bra, demanded entrance. She gasped as I slid into her wet, virgin pussy, but her cries soon turned to moans. I pounded her hard, her big ass slapping against my thighs, her tight cunt gripping my cock. When I realized she'd never been fucked in the ass, I lubed up and pushed in. She squealed, but her body betrayed her, juicing up as I fucked her tight little asshole. I filled her with my hot cum, both holes leaking as we collapsed, panting.
