They were all fucking in the same position. Missionary.I started checking out who the participants were and received my second shock. The first couple was my Uncle Harold and my sister Tracy. They were fucking slowly and leisurely. The second - my brother John and our neighbor,. Now you gonna do as I say or am I gonna have to tell mom what you’ve been up to?” She said sounding pissed off and very honest about her threat to tell mom.Of course I was afraid she would tell mom and I wanted not to get in trouble with mom so I took off my hands off my cock and looked up so as not to make eye contact.
