Do whatever you want with the best mistress I've trained to make my girlfriend a double affair, a secret hot spring date

A secret hot spring trip... a double affair that no one should know about. A sex friend that can be enjoyed without any worries about her sexual preferences being matched. Aika, a new wife with a masochistic attitude that wants to be bound by her heart and body, has no stimulation in her life with her husband, so she has begun to seek a relationship with me. She begs for restraint, and is so lewd that she is intoxicated by the intense thrusts, deep throating, spanking, and choking. Her fine white skin, her small, delicate body, and beautiful H-cup breasts...don't you get even more excited when you think of her as someone else's woman?
