[Chinese]VEC-524 A secret between me and my friend's mother. The thing about being forced to have sex with her and cum inside... Umi Osikawa.

His first love was his friend's mother, Umi. Noguchi, who has come to visit her friend's house, can't help but wonder about the beautiful and kind Hami. But the other party is her friend's mother. She knew from the beginning that love would never come true. Still, I can't give up on Umi. If it's a love that won't come true anyway, whatever happens! Unable to turn back, Noguchi frantically pushes down Hami and attacks her with her desires.
