[Youkandou (Youkan)] Majo Minarai (♂) to Sakusei Slime {Chin²}

A witch's apprentice serves his voluptuous mistress by day—studying magic, performing house chores, and offering his body for her ongoing 'fluid collection' research. Dressed in a frilly maid outfit and stockings, the delicate crossdressing tomgirl is handed over to a ravenous slime that invades both his tight ass and small penis simultaneously, milking multiple sobbing orgasms from him while his mistress coaches the creature deeper. Between breathless pleas of 'don't go into my butt too' and a deep fisting that has her cooing 'there it is,' this crying apprentice discovers his training demands far more than spellwork.
