I am a convenient rental brother! My sister rents me to a female friend! we take a bath together, we sleep together in a futon... An older sister who enjoys a pseudo-brother experience. but we're both adults.

My sister rents me as a pseudo-brother to a female friend who has no younger brother! we take a bath together, we sleep together in a futon... Anyway, my role is to do everything I want if my sister has a younger brother. But each other's body is an adult ... as expected, it responds to various things in a bath or co-sleeping and super erections! But my sister and I seem to be very fond of such an initiation, and it is a momentum that will last only one night and two days after crossing the line! Honestly, it's 100 times better than my real sister! It's kind, it's erotic.
