Slowly, hepushes forward and my mouth opens as he opens my pussy. I can FEEL himin me. His dick is pressing on things inside of me and it's the most...onderful feeling in my life. Indescribably good. And further he pushes.I feel like I can't breathe. He's filling me up and I want more. Ido... something and my muscles grip at his hot, thick cock. "More," I gasp. "Oh god, more." I can't help it. I shove back andthen scream as his knot nearly splits me open. I'd forgotten about it.Oh fucking. It subsides momentarily as I hear him press down to my ears and hiss, "Suck harder!" Maybe if I do, he won't push my head down so far onto his cock so I endeavour to suck as hard as possible, ignoring the pain at the back of my throat caused by over-stretching to accommodate this hot fleshy organ. Wanking the stem whilst sucking the head seems to have the desired effect of releasing the back of my head, so gratefully I suck and try to mimic my friend's head bobbing up and down the shaft of his. “Yah, but that is also exciting. It's more exciting when you control your moans, biting your lips when I make you cum,” Dad said looking at me. Kissing more, I started undoing the buttons of his shirt and then took it off. I brushed my fingers on his broad chest and abs. His one hand was squeezing my boobs slowly and the other hand was on my thigh. “Give me your cock, Dad,” I whispered even though there was no one in the house who could hear us. Dad got up and undid his pants. I pulled them. I think Lori was more interested than the kids. She wanted to keep tabs on them and had set up parental content blocks. I stayed clear, not wanting to get blamed for breaking anything!Late summer 2009. Robby would be heading off to college soon. He graduated with honors and earned a scholarship to help with his engineering degree. I guess he acutely was paying attention all those times he helped me work on the cars and lawn tractors. Jane was starting her senior year and wasn't sure what.
