Des:My sister rents me out as a fake younger brother to a female friend who has no younger brother! Take showers together, sleep on futons together... Anyway, if my sister and her friend had a brother, it would be my job to do all the things I wanted to do. But the other persons body is that of an adult... Sure enough, he had different reactions when bathing and sleeping together, and he had a super erection! But my sister seems to really like this kind of erection, and it seems to have expired. Its supposed to be only for one night or two, but its probably expired! ! To be honest, she is 100 times better than her own sister! Tender, erotic...
