He kneeled in front of her and started to eat her out. He started by kissing her all over her wet pussy. When he finally found her erect clit, he latc...ed onto it and didn't let it go."OOOHHHHH MY GOD, CALEB! YOU'RE DRIVING ME FUCKING INSANE! I'M GONNA CUM!"When she came down from her orgasm, she brought his lips to hers in a passionate kiss.She whispered just barely enough for him to hear it, "Give me your cock NOW."Without a second of hesitation, he pushed into her. He was turned on beyond. I stood there for about ten seconds as I watched my mom shove her tongue into her sister's cunt. The same smooth, hairless cunt I had been eating and screwing all week. Carol made eye contact with me and asked “Aren't you going to fuck mommy?”. I nodded and went to stand behind my mom who was on her knees with her face buried between her sister's legs and her ass up in the air.I entered mother's pussy for the second time that night. It was still just as wet, warm and inviting as it was when. For the rest of the week I was not allowed to get within 10 feet of her and our sleeping arrangements were changed. Brenda stayed in the small back room and I was moved to the front where I shared a king size bed with my mum. This had certain advantages though as the adults didnt retire until 2 hours after us kids were packed off, so I now had time and space to have a wank. The following week we all returned home, I was grounded and the atmosphere was very frosty. Nothing much was said until. Mmmm…she looked like she would be fun. One day I came to the gym to play racquetball and I didn’t see her at the office. I didn’t think anything of it and went to the court. On my way I saw her working out , doing bent over rows and damn… her body wasn’t just tight, it was sculpted. I could feel my dick struggling to bust out my pants. There wasn’t anyone else there. She smiled when she saw me and …I don’t know what came over me, but smiled back and asked her if she wanted to join me for some.
