A week and a half into July and Tracy tells me that she has to go out of town for the weekend for work (she is a photographer). Now I’m really freak...ng out; what would people think of a 24, almost 25, year old spending a weekend with a 16 year old girl….alone.The morning after Tracy left, I walk into the living room and I’m just floored. Lily had been sleeping on the couch, only this time she wasn’t wearing pajamas like she had been. She was lying on her stomach, wearing nothing but a short. After I had orgasm a few times I pulled of his fist, and licked his arm clean of cum, he turned me around and fucked my ass, refilling it for me, as John sat watching, I half stood in front of him with cum running out of my ass, before sitting back down. John was quite, but then said, it looks the same as fucking a girls ass, I told him over the years me and Lyn had got guys into bi sex, by them thinking it was Lyn's ass they were fucking, but it was mine, and then after they had cum in me,. God they are beautiful Betty but they should not be covered up with a bra. Grandpa unhooked mom’s bra and took it off of her. Mom really did have nice tits. That will be a hundred bucks please, mom said.Grandpa reached into his pocket and pulled out a hundred dollar bill and gave it to mom. I was just k**ding dad, she said. Not so, he told her, a deal is a deal.He downed his drink and asked mom for another one.Dressed like this, mom said. Oh yes, I want to watch you walk around with those. "'Morning!" she smiled at me happily. I went over and gave her a big hug and a kiss."Hey baby," I whispered in her ear as my hands roamed across her back, then squeezed her ass. "Have you two been naughty this morning?" No, we were just teasing you. I didn't want to fuck without you being able to join," she said sweetly."That was nice of you." I'm a nice girl!" she giggled."Yes, you are. Very, very nice," I teased, letting my eyes roam over her body slowly and deliberately, marveling again at.
