C107 Extra Book

Eri hugs Master and insists on quickly replenishing the mana he spent working hard for her. They kiss, then Eri performs oral sex on his penis while tasting thick mana as he praises how good it feels. She opens her coat to reveal special string lingerie worn for the day, after which Master penetrates her from behind in hard thrusts. Eri says it was a really good time and she wants even more of Master's mana.
