When Miku finds out that her son's friend is a virgin, she seduces him on a whim and takes his virginity. Miku is satisfied with the sex with the cute virgin, but... "I can't forget what happened the other day. Can we do it again?" Miku continues to cum endlessly as the young, strong, monkey-like, insatiable cock continues to pressure her into sex, regardless of whether her son is there or not.
