PPP-3523 I became fully aroused while surrounded by my mother-in-law and her younger sister at a mixed-gender hot spring. A secret overnight trip where I was thoroughly exhausted by the frustrated sisters until morning

A one-night trip with my beloved mother-in-law, and her younger sister is coming too, so we head to a hot spring inn with mixed bathing. Sightseeing and meals are nice, but what we really want is that kind of fun. After dinner, while I’m in the bath, my aunt suddenly barges in, notices my arousal, and things get heated in the bath. The three of us enjoy a private open-air bath together and the mood becomes increasingly intimate. Back in the room, while we’re drinking, the atmosphere turns suggestive. You want to be with your mother-in-law, don’t you? my aunt says, and I finally get my long-awaited chance with my mother-in-law. When I wake up in the morning, my mother-in-law and aunt discover my morning arousal and tease me nonstop.
