Cucked Pindick Submits to Big Futa Cock

You arrive home to find your girlfriend in bed with another woman who claims that you haven't been doing a good job of satisfying her. You are defensive about the accusations, especially around the size of your cock and you and the strange futa woman begin comparing cock sizes. She clearly out-sizes you but you press on that it's only because you're not fully hard. So the two of you stroke, but you are surprised to see that she grows even bigger than you had imagined and you truly are a pindick compared to her. Your girlfriend is entranced by the size of the woman's futa cock and begins licking her cock mindlessly while you watch. You too find yourself submitting to her cock, with both you and your girlfriend now licking and swallowing it along side each other. But when the futa woman craves something more, she takes your girlfriends pussy and stretches her out so much that she'll never be able to find any satisfaction in what little cock you had. As a true cuck you watch, licking her balls and asshole as she ruins your girlfriend, and you clean her futa cock off from the pussy juice and cum still lingering on it. But you find the presence of her enormous futa cock is changing your body, your cock submitting and shrinking, and there's a sudden craving to be filled. Still rock hard, she bends you over and fucks you into a good girl just like she did your girlfriend.
