My wife wore a very short red Miss Claus dress that barely covered her peachy ass, a pair of black hold up stockings with a sparkly red seam up the ba...k, high red heels and a Santa hat; she looked HOT.I had my orders as to what chores I was expected to carry out. These would not take me all day so by lunch time I was in the shower and ready to sit down in front of the TV with a glass of wine, in my boxer shorts and t-shirt. I was also looking forward to her return and seeing her in that outfit. My god! It was such a turn on! I started massaging her ass crack….she jerked! Before I could do anything, she changed her position & slept on her back. I was freaking out. My hand was stuck beneath her plumpy ass! I gently pulled out. I took a clean look at my beautiful sis. My room was lit by moonlight, her beautiful face, pink lips,her round boobs, flat belly, curvy hips, then I noticed that due to my activities, her pant had slid down a bit & I was able to see her panty. I tried my luck &. It just occurred to me he was going to find out the truth about me."I promise I don't have anything. Please can't i just pay a fine or something." Oh that's what they all say, and yet I always find something else."He walked over and began frisking me, very methodically. He ran his hands up and down my chest, making sure to pass over my nipples a couple time in the process, making them hard. Then my sides and down my back. He flipped up my skirt and exposed my panties, running one fingers along. We’d fuck like there was no tomorrow. One day, when Donna and I were naked in bed, having sex, I heard, ‘Dad, I’m ashamed of you!’ I’d forgotten Tiffany always had a key to our house, she’d come to visit over the three-day Labor Day weekend and didn’t call because she wanted to surprise me. Now it was my turn to be mortified. Donna and I must have looked pretty embarrassed trying to cover ourselves with Tiffany looking on. I was at a loss for words. I don’t recall exactly what I said, but it.
