Following a prank by a cheerful classmate, I, an introverted girl who secretly touched her own breasts, finally fulfilled my wish and made love with the dormitory supervisor I had always admired. (Nan Yu Liu SNOS-308)

I'm Murata from the university's Ekiden (etiquette club). I live in this dorm with my fellow club members from the same university. There are about 10 of us in total. Although we get along well, to be honest, I know I can't really fit in. Simply put, everyone else is a cheerful, outgoing guy, while I'm a gloomy, introverted guy. But I'm happy living in this dorm. That's all thanks to our dorm mate, Minami. She's cheerful and kind, and she treats people like me with the same gentleness. She's very pretty, and her breasts are huge. To be honest, I've fantasized about her a few times. On the other hand, the cheerful guys always tease Minami and are very casual with her. They'll jokingly rub her breasts. I envy those big, soft breasts that everyone's rubbing, but I don't have the guts to do it myself. The most I can do is blend into the crowd of people rubbing her breasts and casually touch them. Those huge breasts I've always longed for, I'm enjoying their softness like a delicacy, trembling in their messy hands. Then, using the lingering sensation on my hands, I secretly masturbated alone. And that's the story of how, thanks to the "sharing" of the sunny boys, I finally got to have sex with the girl I admired, Ms. Nan.
