she gets fucked by other guys

I too love to watch my girlfriend get fucked by other men. We started doing it about 6 months into our relationship. It's been 4 years now. It's not a daily, weekly, or even monthly thing. We have never done the gangbang thing, but she has fucked up to 4 guys in one night while I watched. She gets off on being a slut, and having me watch her, and I enjoy it too. Plus, sloppy seconds sex is hot. Total turn on, and to be fucking her with his cum in her and hearing me telling her how she loved him fucking her is hot. She loves stranger sex. Loves black cock (we are a white couple). Loves getting cock bigger than mine. It's all in good fun. We have an understanding.
