Back in senior year of I started dating one of the "Summer" twins (fictional name for privacy reasons). The summer twins were a year younger than me ... tall blondes cute and identical. One would keep her hair down the other in a pony tail and that's pretty much the only way to tell them apart physically. Personality wise Sarah was much more of a good girl ... dressed conservatively and had wholesome hobbies. Sabrina was the opposite a wild child who like to party.... Why did I try dating the good one? ... frankly Sabrina was a little scary... anyway we dated for about 2 months (ages in high school terms) we would make out and get a little handsy but she would want to go much further.... well it didnt last much longer than 2 months because there was a valley party one night and I went with a few friends. Sarah did not come with she was studying for exams ... we sat around drinking beers and hard lemonade getting pretty drunk when all of a sudden there she was.. Sarah appeared before me told me she had finished studying and wanted to have some fun .... she drags me away from the bonfire behind a set of bushes sits me on a bench and we start making out.... her hand moves down and pulls my cock out before she drops to her knees .... I look at her with my cock in my hand and ask "your ready?" she grins at me before taking my cock in her mouth she's going right at it and im loving every drunk second... a few mins in she stops and puts her hair up into a pony tail.... she keeps sucking and working my cock with her hand ..... she's brining me to climax and i look at her and say "Sarah ... im close " she doubles down and my balls explode in her mouth ...... she sucks every last drop and lets my cock go ... she stands up licking her lips grinning at me and say's "It's Sabrina ... and your welcome" ... My mind was blown ... I didn't know what to do and stayed quiet the next day ..... she didn't tell her sister and we started fucking around until Sarah caught us fucking in her bed one afternoon..... so needless to say we broke up after that ..... Live and you learn
