[HUNTB-528] I'm a convenient rental brother! My sister rented me to a female friend! Take a bath together, sleep on a futon together... A sister friend who enjoys the pseudo-brother experience. But we're both adults

My sister rents me as a pseudo-brother to a female friend who doesn't have a brother! Take a bath together, sleep on a futon together... Anyway, my role is to make everything I want to do if my sister and friend have a younger brother. But both of them are adults ... As expected, I reacted in various ways in the bath and co-sleeping, and I got a super erection! But my sister friend seems to love such an erection, and it crosses the line and it seems that it should be only one night and two days is overdue! !! Honestly, it's 100 times better than my real sister! It's gentle, erotic...
