[HUNTB-528] I'm a convenient rental brother! My sister rents me to her female friend! Take a bath together, sleep on a futon together... A sister friend who enjoys a pseudo-brother experience. But both bodies are adults (Censored)

My Sister Rent Me As A Pseudo-Brother To A Female Friend Who Has No Brother! Take a bath together, sleep on a futon together... Anyway, if my sister and friend have a brother, it's my role to fulfill all the things I want to do. But each other's body is an adult ... As expected, it reacts variously in the bath and co-sleeping and gets a super erection! However, my sister friend seems to love such an erection, and it seems that it is overdue and it is supposed to be only one night and two days, but it is likely to be overdue! ! Honestly, 100 times better than my real sister! Gentle, erotic...
