sistersfamilyaffair: After a day of swimming at my sister’s place I went to find a towel and accidentally barged in on her getting changed in the bathroom. “Oh geez, sorry sis,” I blushed, trying to avert my eyes from her half dressed form. She just chuckled, “Chill out kiddo, you just saw me twenty minutes ago wearing way less than this.” She gestured to the wet bathing suit hung over the curtain rod. I admit she had a point, after seeing her in a bikini this was fairly tame. “Check this out, I’ve been swimming every day while my fiancé is at the office. Check out my glutes, they’re rock hard!” She grinned at me through her reflection in the mirror and stuck her ass out invitingly. “Go on, give ‘em a feel. I didn’t do all this hard work for nothing ya know.” Sliding up behind her I pressed my palms into either side of her firm backside. A little gasp escaped her lips and she teasingly pushed her hips backwards against mine. Our eyes met though the mirror and my sister grabbed her top and pulled it up, flashing me her tits though her reflection. She laughed at my shocked reaction and I could feel my unwitting erection starting to tent my swim trunks. “Ooh, speaking of things that are rock hard…” She flipped around and, pressing her flesh against mine, slipped her tongue deep into my mouth. Suddenly, a knock at the door brought us both back to reality. It was my sister’s fiancé, coming to look for her. “Hey honey, are you nearly done in there?” he asked through the bathroom door. “Uhh.., mm yeah!” my sister replied, untangling her lips from mine. “Just need a few more minutes.” She pulled my cock free from my shorts and was stroking it as our mouths smacked together. “What’s that noise, babe?” “Oh, I uh, I’m just taking off this wet suit, you know? It’s alright, just head back downstairs. I’ll be finished soon.” “Did you see your brother around?” he asked. “He was here just a minute ago.” “Mmf mmm. No clue, baby!” my sister said, now slipping her panties down her naked thighs. “Look, I’m busy right now and need to get fucked…err focused!”“Alright, Sorry,” he said. “I’ll leave you alone.”“Thanks, baby. You’re so fucking good.” -- source link
