Sister dating hot lesbian, getting turned on, help
My sister is bisexual, and right now she has a girlfriend. Due to property prices both me and my sis still live at home, and we share the second floor of our parents house and a bathroom. Our parents have been ok with boyfriends staying over and now girlfriends, but for me it's been hard. The sound of two people having sex is a turn on, but not when it's a guy nailing your sister, now though it's a girl. I have always been turned on by lesbians (see porn history) so now I get such a hard on when they have sex, and yes I have listened and jerked off, even though it's my sister.
What makes it so bad is this girl is so freaking hot, and when parents are not here she walks round the house in a t-shirt and panties. My sister just says to her "don't worry that's just my little brother" (I'm 19)
Anyway I think this girl knows I fancy her and plays up to it, making sure I get an eyeful. So here is my dilemma, super hot girl naked in the next room, I can spy on her but will see my sister naked to. So what did I do, I'm a guy, a spied and wanked off. It so easy to watch from the bathroom. Here's the thing, I used to try not to look at my sister, but one day I thought 'she's hot too' now I just enjoy my live sex shows and try not to think about it being my sister.
Am I a pervert, or just a guy? Anyone else experience d similar?
