Since my dad is the volleyball team coach, our house has become a lodging place for athletic girls from out of the prefecture. I hadn't really paid attention to it before, but now I've realized that living under the same roof with teenage girls is an environment that's way too erotic! Seeing them wandering around carelessly and defenselessly in sexy outfits every day makes me fully erect! When the girls found out, I thought they'd tell my dad, but it turns out these teenage girls are also very interested in dirty things. They want to relieve their stress built up from strict Spartan training with my dick!
