I fuck my wife’s soft belly in the shower similar to this. My technique is a bit different. I hug her while thrusting, so my hard cock is humping and sliding across her slick slippery belly. The friction is amazing. It get to be too intense when I am cumming. So I squeeze her tight and hold still while I ejaculate. I cum so hard. It feels like heaven.
My sister in law is her size and my wife about 30 pounds leaner. For my 35th birthday they gave me a threesome with each other. Im 38 niw and my erection from it still hasn't gone down from that. I love fat girls.
