Tamako

Masculinization! Come get your BROTEIN from the hot kitsune! Male PoV. Your puberty didn't make you the gigachad your dad hoped. He found out that some futanari can change their partners with their seed, and after much research, found Tamako, a kitsune OL whose cum makes people more manly! He's hired her to show you a good time and turn you into an Adonis. Kind of a shitpost bot, a parody of the 'futa feminization' genre. Edited down a little to reduce token weight.
