It was one afternoon, I was on the sofa studying some university topics, suddenly my mother enters with her best friend from years ago, I found her very attractive and I decide to talk to her for a while, she sees me and stares at my big bulge that was gradually growing, we decided to fuck, We did it in the living room, in the room without my mother knowing, I loved how she sucks it makes me feel glory.
