I still live with my mother but my sister lives alone but some times she shows up, most of the times when she knows I'm on my day off at work and our mother is not at home. She says she likes to have sex with me because it's all that she needs. She needs a fuck from time to time and doesn't want any type of relationship with a guy. She just wants a fuck without anything or anyone attached, and that's what she gets with her older brother, me.
