Insidious! Seduced my sister's boyfriend!

My sister Sarah recently got a super cute boyfriend!! Every time we see each other, my head goes crazy and I imagine how he fucks me really horny.. Today I came up with a good excuse to invite him to my place all by myself, but supposedly I have a problem with a lamp In reality, I'm expecting him in hot underwear, because Sarah told me that he's really into nylons! Apparently my little sister has already revealed that I'm a little bitch because I once stole a boyfriend from her, but then he got even hornier and the joy grew with it ;) Wow little sister, respect, the best guy you've caught so far !
