I was Horny

To satisfy my need for sexual release, I started to masturbate and was caught mid stroke by my sister. As it turned out she was also randy, we decided to take care of each other's need. This is where I lie and say I'm the greatest looking man alive and sister is drop dead gorgeous. Neither is true, both a little overweight and on the plain side in looks. But we've always gotten on very well and so us fucking each other wasn't a giant leap in our relationship. She is on a conceptive and so no problems with get pregnant and at the neither of us were in a relationship. But we've both since have found a partner, but that hasn't stopped us fucking each other. We don't do as often as before we got new partners, but we still do fuck on a semi regular basis.
