My name is Rachel and I I was waiting for my boyfriend to pick me up from work when I had to poo really badly. I hadn't been since the previous morning and my boyfriend was running late. I phoned him to ask where he was and while I was on the phone I started losing control and I pood in my knickers a bit. I managed to stop it before too much damage was done but it smelled. When he finally turned up he noticed by the smell I'd had an accident in my knickers and he said it was so hot to see a girl do that. I thought he was just trying to humour me so I wouldn't be so embarrassed but I noticed he was getting an erection and I found it quite a turn on as well. As we drove home he patted my knee and suggested I finished it in the car as I would feel better and I started rubbing his crotch as I pushed a huge poo into my knickers. My hand felt wet and sticky as I was finishing off and I realised he was cumming in his pants.
When we got home I went to the bathroom to get cleaned up and my boyfriend followed me in as he needed to use the toilet. He took my dirty knickers off me and put them on with all my poo in them. He was hard again and I masturbated while he added even more to the smelly pile and we cleaned each other up in the shower before making love for over an hour giving me four intense orgasms.
