Female Teacher 1

Busty lesbian teacher Ayano has to keep her relationship with cute student Yui a secret. One day at school, Ayano finds a stash of pictures of women who've somehow grown big hard dicks, and she can't stop thinking about becoming one of them so she can fuck Yui! Ayano learns that if she wants a penis of her own, she must ask Kouki Morizumi, president of the high school's Black Magic club. Kouki agrees to perform the ritual to give his teacher a cock, but for the magic to work, she has to ingest his semen at least 100 times! Even worse, Kouki seems to know about Ayano and Yui's affair...
