I dumped my stuff in their guest room and Grandma served up lunch. We chit chatted. I took a quick nap. When I got up, we had dinner. Then, grandma suggested we go out. She and grandpa played bingo every Saturday night. Bingo? I told them I'd drive them and drop them off. While they played bingo, I headed to a nearby tavern and had a couple of cold ones. Boy, did that beer taste good. At nine, I drove over to pick up the old folks. Gramps was tired. Grandma suggested we all squeeze into the front seat so she slid in next to me, with grandpa against the door. The whole drive home, gramma's thigh and upper body were pressed against me. Every once in a while, she'd grab my arm as she talked. I noticed that she'd squeeze my bicep and just leave her hand there. Pretty soon, I could swear I felt her pressing even closer against me. I thought I was imagining things and swore at myself to cut it out.
We got home and gramps said he was heading to bed. He headed into the bedroom. Granma and I opened up beers and talked. After about an hour, granma started talking about her "modelling career." About how pretty she had felt, and how good she had looked. I kidded her that she still looked great and she could probably still model. She laughed, but I insisted she could. I told her she should go change into something and model it for me. She laughed and said she'd just bought some nice clothes. Finally, she agreed.
I opened another beer while granma was in the bedroom changing. After about ten minutes she came back out and my jaw practically dropped. Grandma was wearing a really short, tight black skirt, high heels, and a blouse that was unbuttoned to show off her very impressive cleavage. She had put on a pearl necklace and some make up. I could smell her sweet perfume. She looked so good, I could feel my cock starting to crawl down by pants leg.
I complimented grandma and she laughed. Go on, I said, do your model stuff. She laughed again, but started pretending she was on the runway, prancing up and down the living room, striking poses. I just grinned and felt my nuts tighten in pleasure. She started twitching her ass a bit, and I encouraged her to "work it out." Pretty soon, she really started swinging her hips and shaking her ample ass. Then, she walked over to where I was sitting on the couch and leaned down, giving me a spectacular view of her cleavage. I laughed and pulled out a ten dollar bill from my pocket. "Lap dance?" I joked. Grandma snatched the bill out of my hand and turned around and shook her ass about six inches from my face. I was in shock. What the hell was going on? Then, she turned around and started unbuttoning her blouse down to her waist. She leaned down and stuck her tits about six inches from my eyes. Now, I was in shock. But I was also incredibly turned on. Instinctively, I reached out and grabbed her tits in my hand. Grandma gasped, and I dived into her cleavage. I could hear her moan and then I felt her hands wrap around my head and pull me closer into her warm, luscious tits.
By now, my cock was ready tear a whole in my jeans. I dropped my hands to grandma's ass and started feeling up her wide cheeks. Then, I pulled her closer to me until she had to fall onto my lap. With a gasp, I felt her settle her crotch into mine. I raised my head, panting. Granny was flushed and panting too. I reached up and ripped her bra off her tits. Wow. Suddenly two huge fleshy breasts were bouncing up and down in front of me. I latched my lips onto a nipple and begain sucking and biting. I could feel grandma's fingers clenching and unclenching in my hair. I reached down and pulled her skirt up over her thighs and then raised my hips to unzip my pants and release my cock. Grandma kept her hips raised while I fumbled with my erect dick. I slipped my dick against here cunt lips and with a little grunt, Grandma lowered herself onto my cock.
