I pulled and twisted Doreen's stiff nipples making her moan and grab at my stiff cock thru my pants. Sam had pulled off Colleen's tank top and was mas...saging her firm melons and twisting her nipples as he pulled her panties down.Peggy had Ruth moaning by now, Peggy's fingers were deeply stuffed up Ruth's hot wet twat while she licked her sisters stiff clit making Ruth's firm legs jump each time her tongue passed over Ruth's stiff pink clit. I unzipped Doreen's skirt and let it slide down her. Finally I looked up and immediately forgot my beer. A young lady (in my mind I never saw a girl or a woman; strange that!) stood there with a smirk on her face.I looked closer; there was something about her. Something... she wasn't beautiful, but yet she was. She had dishwater blond hair cut short. A pixie face with a cute upturned nose. Not really tall, maybe 5'6", slender but curvy, probably a little underweight for her height. She had a white blouse with a black skirt. The blouse was my. Christy informed me that “real spankings are harder than that.”So I swing harder, leaving big red marks across her bottom. I was growing the biggest woody of my life in my sweat pants. It was more than seeing her gorgeous young body. Being able to dominate it was a powerful aphrodisiac. After 20 strokes I stopped. When I finished, Christy turned and hugged me. It seemed that she pushed her hips firmly against my erection and held them there just an instant. It was probably just my imagination,. She acted like she hadnt seen anything, but you could tell she saw it because she was blushing quite bad. However, we began to discuss what she needed me to do and how much she was going to pay me. She asked me if I could trim the bushes, do some weeding and make a tree fort for her kids. She then told me that she would pay me $250. Of course I took the offer. The next day I came over and began by trimming the bushes and eventually ended up in the backyard starting the tree fort. A couple hours.
