Over the last three months I've been having an affair with a guy from work. He's everything my husband used to be before he found drink was a substitute for a relationship. With my husband away fishing with a mate of his a week ago, I invited my work colleague home at lunch time for sex. We didn't make it up to the bedroom as I was that horny and with his cock rock hard from twenty minutes of me sucking on his dick, I had him fuck me in the arsehole as I was bent naked over one of the kitchen bar stools. I was almost to the point of orgasming when the back door opened and in walked my fourteen year old daughter. She'd come home from school for lunch and saw everything from outside first, as the back door is clear glazed. From what she said later she'd stood and wacthed me being fucked up my rear for couple of minutes, before deciding to open the door and then confronting us. To top it all off my colleague came inside me moments after the door opened, and when he pulled out of my arse his cum leaked out all over the floor. Lots of very loud shouting and screaming later, I calmed her down and tried to explain with colleague having been sent on his way, my daughter doing that. She told me yesterday she's deciding whether to tell her father or not. The deciding factor will be if I finish the affair with my collegue and look for another job.
