僕は大学の駅伝部に所属する村田です。同じ大学の部員たちとこの寮で暮らしています。部員は全員で10人くらい。仲が悪いわけではないけど、正直みんなと馴染めてないことは分かっています。簡単にいえばみんなは陽キャで、僕は陰キャ。でもこの寮での暮らしは楽しいです。それは寮母のみなみさんの存在のおかげです。朗らかで、気さくで、僕なんかにも分け隔てなく接してくれる。キレイだし、胸もすっごく大きくて、正直何度もオカズにしたこともあります。一方で陽キャのみんなはみなみさんのことをいじったり雑に扱ったりしています。軽いノリでおっぱいを揉んだりしています。みんなに揉みしだかれる大きくて柔らかそうな胸がとても羨ましいですが、僕から自発的にそんなことをする度胸はないです。せいぜい僕にできるのは、みんなが囲んで揉むのに交ざって、さりげなくおっぱいを触ることくらいです。ずっと密かに憧れていたあの爆乳を、みんなの乱雑な手に紛れて、震えながらも味わうように柔らかさを堪能するんです。その手に残った感触で、ひとりこっそりオナニーをします。そんな僕が、陽キャのみんなのおこぼれで憧れのみなみさんとおこぼれSEXできた日の話。
I'm Murata, and I'm a member of the university's track and field team. I live in this dorm with other members of the team from the same university. There are about 10 of us in total. It's not that we don't get along, but to be honest, I know I don't really fit in with everyone. To put it simply, everyone else is outgoing, and I'm an introvert. But I enjoy living in this dorm. That's all thanks to Minami, the dorm mother. She's cheerful, friendly, and treats everyone equally. She's beautiful, and her breasts are huge, and to be honest, I've fantasized about them many times. On the other hand, the outgoing members tease Minami and treat her roughly. They casually grope her breasts. I'm really jealous of her big, soft-looking breasts that everyone gets to fondle, but I don't have the guts to do something like that spontaneously. At best, all I can do is casually touch her breasts when everyone else is surrounding her and groping them. I finally got to touch those massive breasts I'd secretly longed for, amidst everyone's rough hands, trembling but savoring their softness. I secretly masturbated to the feeling that lingered in my hands. This is the story of the day I got to have sex with my beloved Minami, thanks to the leftovers from the popular kids.
