You're laid on your back, your large stomach sat down on top of you. Then her squirming starts anew, & it does not disappoint. She repeatedly kicks with both her legs in unison, each kick pushing out your gut by almost two feet. You grind into your gut to help you cum, not that you need it. Within moments of her kicking & begging & squirming you blast your load hard into the side of your gut. As you cum your gut tightens up, squeezing your prey & restricting their movements to little more than wriggling.
You look over to ralts who, despite themselves, is clearly enjoying the view. You ask her, "You wanna rub my gut?" She looks startled, but shyly walks over to you & rubs your tummy.
