It was one of those drunken shags when we'd got home from a night's drinking and flirtation and couldn't even make it to the bedroom.
We were going at it on the velour sofa (this was a few years back!) and I thought the wife's pussy felt unusually soft going in but a bit rough on the back stroke.
She suddenly stopped me and asked me what the hell I was doing cos I wasn't shagging her pussy. We looked down - I'd been happily screwing the gap between the seat cushions for 5 minutes!
Actually, it didn't feel that bad when I come to think of it.....
