While his parents are away, a virgin stays with his adult childhood friend Misuzu. Seeing her lounge around with her ass exposed leaves him rock hard, and he pulls aside her panties and pushes inside. Overwhelmed by his first pussy, he accidentally comes inside almost immediately. Hoping to hide it, he keeps pounding as Misuzu orgasms with a dazed expression, then loses control and fills her with load after load until an unexpected miracle occurs.
