I was targeted by a double-sex sister I met in the men's bath at a super sento. I straddled my cock that I had erected through teasing pranks and was forced to insert myself raw.

Little sisters met in the men's bath at a super sento. I grinned as I saw myself changing clothes in the changing room. They chase after them both in the washing area and in the bathtub...the innocent girls unconsciously show off their breasts and pussy, touch and tease them without their consent, and then have fun seeing them grow bigger. Even after evacuating to the sauna, he still chases after her, instead of her erect cock, she straddles her pussy and inserts her raw! A nymphomaniac harem experience where she is squeezed out by her sister's pussy, which is amusing when she comes to sperm coming out!
