I fingered myself again and got the vibrator out of the tool bag and used it on myself. Trying not to moan. “Big D... Big D... have you put that vib...ator on…Big D.”Fuck. A part of me still wanted to keep up the pretence of the situation. I liked her thinking I was big D. It may not have been the humiliation I wanted to serve but it was in many ways. I reached for the tickle feather and stretched out my spare hand and tickled her nipples. How Julia giggled and giggled. Wiggling around and. I worked towards my task of always leaving lipstick marks on the guys groin I sucking it deeper as he fucked my mouth. Gagging a few times till my lips met his groin I pushed and shook my head leaving bright lipstick marks. Pulled off it holding it looking up at him with a smile as the drool and saliva hung from my lips. He grabbed the back of my head yelling out “fucking slut” and rammed his cock down my throat and I did what I do best sucking and making love to a hard cock. In a few minutes. Normal things. Until I asked an innocent question.“Mom, what is Dad getting you for Christmas?”Mom look startled, and her eyes locked onto Dad. Tension flooded from them.“I already have your father’s present,” she said, never looking away from him.“Show us, Mom. Come on,” Abby chirped.“Please, Mom,” Betty chipped in.“Oh, I couldn’t.”“Of course you can, Mom. Show us your present,” I said. I did not think about it being a command to a kitten, but it was.Mom’s eyes moved around the room, looking. While lying on the sofa and staring at his perfect body he caught me staring….He smiled lightly and continued training…After a few minutes I saw him rubbing his dick…He stood up and came next to me…He just put out his dick in front of me and I was amazed…It was huge…I had seen some porn before that but I had never seen something bigger than that piece of meat… He asked me if I wanted to do him a blow job and saying nothing I just grabbed his beautiful dick and started licking it…It felt so.
