As I leaned in, I could smell her musk, running my lips across the slick head of her cock, and down the shaft, she squealed, so I started running my t...ngue around the head, and lightly down the shaft, savoring the taste of her precum. It tasted so sweet, slowly I took her into my mouth, working my tongue in circles, sucking her in and out. God it was heaven, I wrapped my arms around her hips and pulled her to the edge of the couch so I could take her all. Still working it slowly in and out of. I told him it was ok and he lay still as my hand slid up and down his 7 and fat cock. I got under the sheet with him and pressed my young body to his as I cupped his very large balls and kissed his earlobe. Dad repeated that we can not do this and he started getting up pulling his cock from my grip. I followed him out of the bed and he stood up allowing me the first view I ever had of his fully naked body. His cock was standing out straight fully rigid and looking large. He was about an inch. Sis agrees. After 50 + years, I am not sure how it happened but somehow, I am sitting up, sis ends up sitting between my legs and I am massaging her neck and back. She has on a "baby girl" nightie (short) and a "puffy" bottom. My pecker is jammed into her bottom. At first I am massaging her over the nightie, then with common sense gone, I slid my hands under the material and rub her neck and back, skin to skin. Sis is content with this. My mind is racing and i begin to massage her stomach.. K it’s just that me and my step mom are going away in the morning and won’t be back until Sunday night”. I left a pause, I didn’t want Angela to know that I had seen their relationship blossom on my secret cameras. “Oh, I didn’t think you got on?” I replied, “And what about Bruiser?” I enquired. “Karen is going to pop in on Friday daytime… er are you back Friday night?” Angela responded. Again I paused before replying, “Well I don’t think I’ll be back until Saturday lunch, do you think Karen.
