I (M) walked into our bedroom. There my gf was, lying on her stomach across the bed. The first thing that caught my eye was her beautiful bubble butt, looking extra peachy in her leggings.
I walked over to her and, as I quite often do, gave her ass a gentle slap. I love the way it feels and wobbles. She turned back and looked at me in the eyes, wearing a full face of make-up, and smiled. I knew that look. She wanted me to do it again. So I did, a little bit harder this time, so it wobbled that little bit more. She shook her ass gently, a sight I love, and is our universal sign for slap and feel me.
So I smacked her ass harder, and gave it a grab. A sure fire way to make my cock rock hard. I slowly start massaging her ass checks, smacking them every so often and watching them jiggle.
