Trapped

I'm 45 and live with my only child my daughter 26, my ex-husband never calls her or has tried to stay in touch either. We've a large dog called Buster as a pup he was always knocking things over, and so we called him Buster. I work from home mostly and have a small home office. It's an old Walkin closet and my desk just fits between the sidewalls at the back of the closet. One day last April I had to put the desk forward as I lost a folder down the back of the desk. The desk doesn't flush against the wall to skirting board, I had intended to have a shower and had completely undressed, but realized I should get the folder first or might have to shower again because dust at the back the desk. There are a set of shelves above the desk I put up for storing things. With the desk pulled forward and cleared of everything I was bending over the desk reaching for the folder and the shelves above slid down onto my back trapping me. My daughter was out and only buster was home with me. I could get out and I would have to wait for my daughter to get home about an hour till she got home usually. Anyway, Buster heard me calling out came sat near me, then got up and started sniffing my body. Before I knew it, he was trying to mount me. Finally succeeding and rode until he came inside me, then he sat down and rested. He was fucking me again when my daughter got home, she didn't laugh or anything, just waited until buster had got off and she got everything off me so I could get up. My daughter then asked how I enjoyed the fucking, adding he's good isn't he. I realized my daughter was letting Buster fuck her, I was a little shocked by his actions at first and had no choice but let him finish. I then asked how long, have you been fucking Buster since the during the lockdown she said he came while I was masturbating and satisfied me. I could lie and say that was the only time Buster fucked me. But I'm his willing Bitch now like my daughter is.
