Due to my parents' remarriage, I gained two stepsisters, so to deepen family bonds, we went on a hot spring trip! When I was sleeping in the same room as them in a river-like formation, both of their sleeping habits were terrible—their yukata was disheveled, exposing everything! Unable to resist, as I touched them, they seemed almost awake, reacting intensely! Excited, one of them turned the tables and attacked me! The other sister joined in, leading to a miraculous threesome! It turned out both were very sexually active, and we went at it exhaustively! I even ended up ejaculating inside both of them!
