I know this sounds like we are bad parents, but man what a turn on!
We placed our son in his pack and play to have a "rest" (he was very fussy and wanted to climb ontop of everything) my husband was working on dinner and I was helping him. when all of the sudden I got a horny rush, we went into the bathroom for a quicky! We never had quickies and well it was one of my fantasies to be taken up against the bathroom sink. Our son never even noticed we were gone. We havent done it since but I was thinking about how much of a turn on it was having a quickie in the bathroom.
