Shared a hotel room with my 19yo stepsister and things got out of control fast. She was masturbating right next to me, my dick was rock hard watching her change. We started touching, fucking like crazy, then she yanked the condom off mid-stroke. We went raw, got too caught up in how good her tight pussy felt, and I blew a massive load deep inside her. Filled her cunt with cum and now she might get knocked up. We're so fucked.
