I grabbed a T-shirt and pulled in over my head. It wasan extra large T-shirt and I had cut it off so that itcame down an inch or two below my tits. Th... neck wasloose and the arm holes were open so that no matterwhich way I moved, I would be flashing skin in somedirection. I wet my short hair to get rid of thecowlick from my nap, and dragged a comb through itleaving it wet. For the final touch, I slipped on a pair of whitesandals that had a 2 inch heel. Not high enough to beuncomfortable, but. He sat on the floor with both legs stretched… laid me on the floor on my back…took my legs on his shoulder…..brought saliva from mouth…applied on my anus and his dick…positioned the dick on the anus and pushed in slowly & slowly till the penis entered upto its root….his hip started jumping on my butts while the dick getting in and out with the strokes.He started moaning uu … nnn …aa ..hh …oh …hh ….I felt hot fluid flowing inside the ass hole;When he left me I sat on the floor….curd like sticky. As I watched the first few fruitless jabs at Erika’s loins, I was reminded of the instinctive motions of a horny dog jabbing the air ... desperate to plant its cock in the needy cunt of his bitch. Although not an elegant comparison, Dad was that horny dog and my beautiful wife was his captured prey.As that raw image occupied my mind, suddenly, I heard Erika gasp and saw that the very tip of Dad’s ruddy cock, wise from years of carnal experience, was finally able to sniff out the opening to her. I tried to gently open them and was rewarded with A quick kiss and "I want to sleep. Good night." And she turned away from me.So there I was, just like Meatloaf wrote "all revved up with nowhere to go." I tried going back to sleep. On one side. On the other side. On my back. On my stomach. Nothing worked. Got up, went to the computer, played around and watched some porn, which didn't help either and only exacerbated the situation. Finally, went back to bed.The time: 2:30am. Still couldn't.
