Plus I had plenty of room for expansion.The day after our meeting I went out to see my sister. She greeted me and asked if I was there for a friendly ...isit or if I wanted to fuck her. I wanted to fuck her.Sheila was twenty-five, divorced for two years, and had a four-year-old daughter. I was almost ten years older than she was.She took her daughter into her bedroom and returned to me naked.What to fuck! She knew why I was there and she was not going to slow me down any. She stood before me in. We started making out for the guys as a show for friends at parties after everyone was pretty drunk. The boys would chant for us (and a few of the girls). Phones would come up and record us sucking each other's tongues into our mouths and grabbing each other's butts. But, it was just a party trick, something we did to be provocative. I mean, I liked it. But, we'd both go back to our boyfriends, who thought it was hot, and let them fuck our brains out and we were cool. Then one afternoon at her. A group of schoolboys came round the corner and passed the letterbox coming toward me. I gulped. They were laughing amongst themselves. They didn't notice me at first. They almost trampled right over me. I gripped my envelope to my chest and whimpered. One of them said, "Watch where you're going," sullenly. I kept my mouth shut and my eyes down until I got to the letterbox. Then I realized the next problem. I couldn't reach the slot to post the envelope. I jumped up toward it over and over. She wiggles her hips as she spreads her legs trying to get more of me to touch her. I drop to my knees, pulling my hand from her wetness. I can smell her lust from this position and feel my already hard cock grow another inch. I grasp the sides of her shorts and panties and tug them down. I lean forward kissing the smooth skin of her pussy.She spreads her legs and my tongue slides through her slit and over her clit. She moans again as she kicks her shorts and panties off her feet. I turn.
