I pulled back slowly. Then I pressed in again hard. I felt her body trembled slightly as she tried to handle my girth. Then she pushed back hard and I...bottomed out in her ass. She reached back and grabbed my blanket. As I slowly pulled back, her death grip on my blanket caused her to pull it off me.I scrambled to grab it. Too late! She turned to help with the blanket. Her eyes widened first in surprise, and then horror as she realized it was he son buried balls deep in her ass. She tried to. Over time he played with it more and more, slipping his fingers into me, especially when he went down on me. I wasn't stupid. I knew what he wanted, but I was even more afraid. I screwed my courage up on Valentine's Day, lubed my virgin butt-hole with half a tube of KY, and waited for him naked in our bed, a big bow wrapped across my ass cheeks. He took me up on the offer. And you know what? I liked it. No, I loved it. After that, I'd let him fuck me in the butt at least once a week. Sometimes. He leant forward putting one hand on Fay’s back for support while inspecting as closely as he dared the insertion of quite a sizeable organ into his wife’s fanny. With my legs across his prick I could feel the arousing effect it was having on him. Pete was seeing for the first time, his wife of twenty plus years, take the penis of another man into her fanny and was not only accepting but calling to “go hard”. Pete never explained to me at least, but maybe to Fay, whether he thought she’d. There was no time, or need for whispers of names, or love, or tenderness. The only sounds were the wet smacks of their flesh colliding as they rutted and the occasional, "Oh, yeah," and "Fuck me, harder!" flew from Margie's hot little mouth.His hands mauled her breasts continuously, pinching at hard nipples and using her breasts as grips to slam her light body ever harder against his steel-like member.Margie started to growl with pleasure as they both neared the finish line. Then Vince's hips.
