Making Do update

Last year my sister Suzie moved in with me and we started fucking Suzie got pregnant. Since then we had a baby daughter named after our mother Clare. Clare 53 divorced 20 years ago and our father Donald fucked off and we haven't anything from him since. Clare on hearing of Suzie being pregnant moved to live with us, she wasn't all that frilled that her son had gotten her daughter pregnant. But with all tests showing the baby was healthy and as the pregnancy progressed, she accepted our relationship. Leading to her sleeping with me on the night baby Clare was born after a few drinks in celebration and me taking advantage of her. Since then however she regularly joins Suzie and me in our bed for sex. Suzie wants more children and we are planning to have more and don't take any precautions, but it's unlikely she will get pregnant before baby Clare is weened.
