My most embarrassing moment happened 3 years ago when I was 15. I was with my family and we had piled into the car to head home after driving to the beach for the day. I was in the hot sun all day and felt kinda dizzy.. felt wierd and kinda lazy. It’s a packed Car with 4 of us in the back and my lil sis wants to sit in my lap, so I let her not thinking at the time. I feel her wet bikini bottoms and her b** start to make me hard and I fight it.. but I start to dwell on it and can feel my c*** get warm and hard against my thigh. I push her b*** up and shift my c*** against my belly as she unknowingly grinds her cheeks around my now swollen c***. I feel dissy and lose control as her bathing suit is wedged up her b*** and her warm skin is beating against me. She laughs and plays with my cousins as she pushes her b*** back trapping my c*** between her tiny b*** cheeks. Lost in some sort of rhythmic motion I grab her hips and pull her b*** against me as I shoot huge streams of c** into my bathingsuit and melt into the guilt I now own.
