SONE-439 My kind and tall girlfriend was seduced by the swimming coach's sex ed. Mitsu Asuka

No matter what I did, it was all for naught. It was my senior from the swim team, Mitsuha Asuna, whom I admired, who saved me from being bullied. Just having her acknowledge my existence made me happy. Even just exchanging a few words with her made me happy. Words are free. If you don't convey your feelings... Gathering my courage to confess my love, she replied with something I never expected: "Sure, with you." I had resigned myself to being single for life, but now I had a girlfriend. Would we be doing things like kissing or sex? That would be fine anytime. Someday... that's what I thought, but unbeknownst to me, the coach's evil hand was creeping closer.
