Note: This story was dynamically reformatted for online reading convenience. Karl and I got dressed. I left my thong and bra on the floor, only pulling on my t-shirt and shorts. Karl saw this and gave me a huge grin. We went out to work on the weeds in the backyard. I let him go first and kneel down to get started. I got down next to him and pinched his ass, making him jump. I gave him a wink before turning to start pulling weeds. A minute later I felt his hand slap my ass. I turned and gave him a grin before he went back to pulling weeds. A few minutes later I reached over and pinched him again. He turned and spanked me again. I moaned and said, "I'm a bad girl, Karl. I sucked a sixteen year old boy's cock and I liked it. Do you think I need another spanking?" He grinned and spanked me again, making me moan louder. The houses one each side of me were empty right then, with only the one behind me having anyone living in it, so I wasn't too worried about being heard or seen but it was still a risk. A risk that had me very turned on. Karl went back to pulling weeds and I waited a minute before I made my next move. I crawled over behind him and, grabbing his hips, I pulled his ass against me. I slid my hands up and under his shirt, feeling the heat of his skin on mine. I slid my hands down and rubbed the hard bulge in the front of his shorts. "Do you want me, Karl?" I asked. "Do you want to fuck me?" "Yes," he breathed. I crawled back and turned around. I got on my hands and knees and looked back at him over my shoulder. He came over and knelt between my legs, looking at me for what to do next. I told him what I wanted and he obeyed. He took my hips and pulled my ass back so I could feel his hard cock through our shorts. He rubbed it against my ass, making both of us moan. I couldn't wait any longer, between the thrill of him being so young and us doing this outside, I needed him badly. "Get your shorts off," I said. I undid min and slipped out of them. He hurried to follow my lead. I knelt in front of him again and felt him slide his cock between my ass cheeks, rubbing its length against me and making me hotter. "I want you inside me," I told him. He put the head of his cock against my wet pussy lips and eased himself into me. Both of us moaned as his length filled my pussy. I clenched my hands, tearing up chucks of grass, as he pushed himself all the way into me. He slid back and then in again and again. He took my hips in his hands and thrust himself into me. I whimpered as he slid his hard cock deep inside me. "Wait," I said. He stopped and I slid off of his cock and turned around. I brought my lips to his and kissed him hungrily. I opened my mouth and licked my tongue on his lips. His lips pared and his tongue shot into my mouth. I broke the kiss and said, "Not so fast. Feel how I do it and then try." I kissed him again, my tongue sliding into his mouth and rubbing against his. It didn't take too long for him to get the feel of how to kiss me back. His teeth bumped against mine a couple of times but I couldn't fault him for his enthusiasm. I kissed him softly and then pulled back. I took off my shirt and laid on my back in the grass. He got between my legs and slid himself back into me. I pulled him tight against me as he slid his cock deep into my pussy. I pulled his face to mine and kissed him again. He returned the kiss eagerly. He pushed himself up and looked down at my body as he fucked me. His eyes watched my breasts bounce as he thrust himself into me. "Touch them," I told him. He brought his hand up and cupped it against my breast. He let out a low moan and I felt his cock twitch inside me as he touched my breast. He caressed my breasts, listening to everything I was telling him to do, very eager to please. He pinched my nipple and I let out a whimper. I looked up and saw him grinning at me as he pinched me again. I whimpered again and he laughed and teased me some more. "Tell me when you're getting close," I said. He nodded and kept driving his cock in and out of me. I pulled his face down to my breasts and had him kiss them. He kissed across and between my breasts, his lips just barely touching my burning skin. He kissed my nipple and then touched his tongue to it, making me moan for him again. He sucked my nipples and little shots of intense pleasure raced through my body at his touch. He lifted his head from my breast and said, "I'm getting close." "How do you want to finish?" I asked. "Do you want to be on top, me on top, or you behind?" I saw his eyes widen on the word behind and knew what he wanted. He slid off of me and I got on my hands and knees from him. He got behind me and slid his cock into me again. He grabbed my hips and thrust, harder and harder, into me. A he rammed his cock into me I felt like I was on fire. I'm bit my lip to keep from screaming as he fucked me. When I came, I couldn't hold back my cries of pleasure. Long, shrill whimpers erupted from my mouth as I felt his cock throb inside me. Karl let out a loud moan and shoved his cock deep inside me as he came. His cock pulsed again and again as he came in me. When his orgasm ended, he pulled out of me and laid on the grass next to me. I looked over at him and I knew I had the same silly grin on my face as he did. We laid there, catching our breath, before I said, "Maybe we should go inside and get cleaned up." He nodded and we gathered out clothes and went inside. We put on our clothes in the kitchen and Karl said, "That was amazing." I laughed and said, "Yeah, it was." "And we did it outside too!" He said. "We could have been seen and everything." "It made it more fun, didn't it?" I asked. "Yes!" He agreed. "So you like kinky, do you?" I asked. He grinned and nodded. "Well, let's see what else we can do."
