[Shotaian (Aian)] Holic～Ojisama no Gokubuto Chuudoku ni Otosarechaimashita [mysterymeat3]

A delicate tomgirl falls deep under the spell of a bald, muscle-bound older man who swore from the start that all he wanted was to make him feel good—and now the boy wears a collar, feminized with a newly expanded chest and a body that aches for his master's touch. Teased with porn on a phone screen, his nipples pinched until his mind goes numb and his own boner stands rock hard, he whimpers that he wants dick, ahegao bliss washing over him as his resistance shatters into pure addiction. What begins as a seemingly harmless invitation becomes relentless anal training that leaves the sweet femboy unable to ever escape his craving for his ojisan's thick cock.
