HUNTB-528 I'm a convenient rental guy! My sister rented me out to her female friend! We showered together, slept on the same futon... a female friend enjoying the experience of being a fake guy. But both of us are adults.

My sister rents me out as a fake younger brother to her female friends who don't have brothers! We shower together, sleep on the same futon... Basically, if my sister and her friend have a younger brother, my job is to do everything I want. But their bodies are adults... so naturally, their reactions are different when showering and sleeping together—super erections! However, my sister seems to love this kind of erection, and it seems she's crossed the line, maybe only two days and one night overdue!! Honestly, 100 times better than my own sister! Gentle, erotic...
