It features elastic ladies as well as breast, butt, clit, hip, penis, and vulva expansion, women's muscle growth, and some very intense facesitting. If any of that sounds like somethin...

This is sort of a follow up to Chosen By Passion, but stands alone I feel. As The Goddess of Passion is only tangentally involved in a man becoming a swole altersex mini-giantess.
