She spy her twin sister while he fucks his boy

it May seem a little strange, but I like to see my sister fuck. Yes, I know. It is not a normal thing to do, but I cause a lot of morbidity. Is my twin sister, so it’s like watching me fucking. Every once in a while, the spio when the guy stays at home. Today was one of those nights. They were both in the bathroom, and when I heard they were fucking, I went into the bathroom in silence. They were in the shower. So I have hidden behind the curtain and I started to watch them. I was so excited, I could not live without it, and I slipped her hand into my pussy. While my sister moaned with pleasure, I infilavo the fingers. I had like three orgasms before exiting the bathroom.
