I just found out my families biggest secret, my sister was born with a pens. They kept us a part growing up so no one would find out as a result she hasn't ever lost here virginity.

All I can think of now is that I want to see her cock and touch it,suck it and let her fuck me hard til she cum up my aching arse.

I can't look at her without getting a hard on.

How can I ask her if she'd like to sex with me??
