” What a trooper, most chicks would have given up by now; she really wanted to please her man. She was now on all fours and she opened her mouth and... my cock slid into her mouth again. I leaned forward and smacked her ass real hard and as she moaned in pain my cock slid all the way balls deep into her mouth. She came up gagging almost throwing up all over the floor. She smiled and said, “Go ahead baby smack your cousin’s ass treat me like that bad girl that I am.”I shoved my cock back in her. I tickled her bush a little bit, then worked my way up her sides and across her chest. I gripped her breasts and squeezed her nipples until she leaned down and offered them to me for sucking. I was up for the task and sucked first one then the other. As I sucked her nipples, I reached behind her and caressed her back. Chris kept grinding her hips into mine as I thrust up into her. My hands made their way down and I gripped that tight ass of hers. Chris moaned and kissed me. I thrust harder into. " Ok we won't count that," I said with a straight face.The evening broke up and I took my sister home."Shit I can't wait to get out of this dress," she said."Do it now then," I suggested."What here?" she turned to stare at me, "in the car five miles from home?" Yeah, get naked now," I said with a big smile on my face."What if we get stopped or something," she gasped."Then you'll have to give the policemen a nice time and just hope there are two of them," I said."Yeah right, well I'm not taking. Man does she look good in a bikini! Huge tits, great legs and a beautiful ass! I begin to apply lotion to her shoulders and back. I have to stop just above her ass and admire it for just a second! I have to think of something else, because my cock is becoming hard! I move south of her ass and rub it on her legs. Then, she turns around and I apply it to her face and neck. I proceed to rub it on her ample cleavage and again my cock stiffens! So, I rub it over her smooth belly and down the front.
