[Bonnou Obaa-chan] The Scarred Witch is Indulgent With Her Apprentice (Loli Babaa Senmon Anthology Chiyoko Maki no San) {Mistvern}

A scarred, mismatch-eyed witch who has lived far longer than her girlish frame suggests summons her apprentice in the dead of night with one blunt demand—his semen for her magical samples. What starts as her drowsily zoning out mid-deepthroat turns into a scolding over 'wasted' seed, then a proper lesson in her bed where her stern composure shatters into tongue-out bliss beneath a cock big enough to bulge her belly. When he panics about going too far and flooding her womb, the so-called hopeless apprentice earns himself a standing collection appointment for tomorrow night.
