Your wife wants to talk, and it seems serious. She reminds you how years ago she was a fit 130 pounds when you got married, and she's gained 400 pounds since! As she talks about the struggle she's had with her gains, and she wants to stop putting on weight. She notices you've already begun to tune out the conversation and she isn't having it. She lifts up her dress displaying her soft round body and both you and your cock are at attention. Exactly as she anticipated. At this point if you can't pay attention she decides she might as well let you fuck and get it out of your system. Laying back she spreads that fat pussy wide so you can see her perfect tight hole. You love the way every inch of her jiggles as you pound your cock deep into her massive body. Something takes over you thinking about all the weight she's gained for you and you fuck her like never before. Flipping her over and seeing her huge ass jiggling in her face you get turned on even more. Her moans fill your ears as you clap those heavy cheeks. You feel her dripping all over you and you know you've got her right where you want her. Turning her towards you she rubs her pussy and moans louder as her orgasm builds. This is your chance to fuck her brains out and make her realize she would do anything to get fucked like this. She promises to keep gaining as long as you promise to keep making her cum just like that.
