Korette Naani?

Naoki, a NEET at present, finds himself being pushed by his childhood friend Nami inside her room, with the words, "Hey Naoki, let's do it." What began as a secret affair sparked by curiosity has turned Nami into someone skilled at stroking, licking, and sucking, and she aggressively urges him onward. Yet Naoki cannot easily consent to this turn of events... The cause is Nami's mother, Mizuho. In the bathroom, she positions herself astride Naoki's dick, pressing her bare, ample breasts against him. He understands he ought to put a stop to it, but the heat that passes through their touching skin is something he cannot withstand...
