I confessed to my college friend's older sister, but she said she already had a boyfriend, so I was disappointed... Still, I couldn't just leave it at that. I begged her just for a kiss, and she agreed—only a little. I felt embarrassed, especially as a virgin, but I was excited to see her body for the first time. She let me undress her, and her soft, big tits felt amazing. She asked if I could look, then took off my pants and said my cock was super hard. She gently gave me a handjob, and it felt incredible. She told me to undress her too, and I was amazed by her pussy. When I asked if I could touch it, I got so nervous my pre-cum leaked out. Sorry. When I inserted a finger, it was slippery and made wet, squishy sounds. She asked if I'd ever licked it before, then begged me to go easy on her clit—though I was nervous about doing it right. But seeing her twitch and shiver drove me wild. Then she said she'd lick me next, took my rock-hard cock in her mouth, and gave me an amazing blowjob. I couldn't hold back anymore. When I asked if I could fuck her, she happily agreed—guess she'd wanted my cock all along. Her tight, warm pussy squeezed me perfectly. She took the lead, switching from missionary to doggystyle and cowgirl—she was absolutely perfect. I was losing control, about to cum. She asked if I could hold back, then told me to thrust harder. I finished with a massive load. Thanks, big sister.
