There were times I would arrive home late after a college activity only to find him already there. Other times I'd get home early and find no one home... An hour or so later Mum's car would pull into the driveway where, surprise surprise, Mark would be with her. He'd get out and help her into the house with the bags of groceries or shopping where she'd weakly explain Mark had kindly offered to help. Why someone usually so sensible would believe someone his age would want to help her out with her. Slowly I dragged my hands up her body, never touching her sensitive areas. She moaned slightly and began to turn to him. He caught her by the shoulders to prevent her from turning, a delicious idea just dropped into my head.I fingers trailed down her arms to catch her hands in me. I brought her arms up straight above her head. I took her arms and directed them forward to lean on the window and causing her to lean forward slightly.“don’t move honey. I won’t hurt you.”“I know,” she murmured.. I pulled off Guy's panties and stroked his hard, uncut cock. His cock was much bigger than mine. Neither of us had much pubic hair. I had never seen an uncircumsized penis before, and I was fascinated as I pulled his foreskin back and forth. I enjoyed sticking my tongue into the end of his cock; there were a few drops of pre-cum which I licked slowly.. We moved into a 69 position and slowly began to suck and lick each other. It was a tender exploration. It was our first real sexual experience. .Open up, hun!”I opened my mouth wide for dad, waiting for his load. A couple a strokes later, he did just that. Aiming his big pretty cock right at my mouth and filled me up with his sweet cum.“ARghh Yess...Fuck! Drink daddy's cum...Mmmm! My little girl is such a hot little bitch...AHH Mmmm!”“Mmm...thank you, daddy!”I loved that 2 men just had cummed for me. I stood up and wiped my mouth with some paper towels from the dinner table. My dad went to the fridge and got 2 beers and a glass of red.
