As with other couples, we had a pair of friends that we regularly socialised with. Often we would discuss sex and, over time, the conversations got more and more daring, pushing back the boundaries. During one meal with Richard and Michelle, Michelle and I had discussed wanking. As a sort of standing joke, we talked about me wanking in the garage while she watched. The conversation moved on and nothing more was said. We finished the meal and got a cab home. Richard and Michelle were staying the night, so the drinking continued. Eventually, the Michelle reminded me about wanking for her in the garage. I said OK. Tracy and Michelle went to the garage while I went to the bathroom. By the time I got outside, Tracy and Michelle were standing in the empty garage with the garage door open
The garage is at the back of the house opening onto the service road. This road is T-shaped and the house was pretty much at the cross of the T. The garage therefore faced straight down the service road. There was no electricity in the garage, the only illumination therefore being from the streetlight immediately outside the garage.
As soon as I got to the garage I stripped naked, and revealed a substantial erection. Michelle noticed my hard cock, giggled and pointed it out to Tracy. I was naked, in full view of anyone coming down the service road, faced with two women. The two women were against a wall, so I leant against the other, took my cock in my hand and began wanking.
