Ginary has been such a good girl that it's time to reward her by fucking her with my cock. I make her get on all fours and guide me in. I then rest my massive belly on her tiny body, letting her feel every pound on her. I pull her chain and order her to rub my belly while being fucked by me. I give her some nice smacks with the riding crop too. You know this Mistress is good at what she does and is going to make her belly sub cum!
