As I laid there on top of her, I let my cock soak in her wet pussy, we heard our mom yell up, "Dorene, Betty's here."
"Oh shit, I forgot she was coming over to go out for her birthday," she sighed as she pushed me off her, "go tell her I'm getting ready," she told me as she ran out of my room.
Betty is her best friend and a bit on the hot side. We all are friendly with each other but that's as far as it went. So, I go down and see Betty sitting on the couch, "She told me to tell you she is getting ready and will be right down."
"Oh, that's alright, I can go up and make sure she is ready for tonight."
"Damn, Girl, looking pretty hot tonight."
"Only turn twenty-one once," she declared as she stood and headed up the stairs. I don't know what her plans were for tonight but the dress she had on was a micro mini dress, and I mean short. Damn!
They were up there for a while and then came down. She had my sister dress as slutty as she was. She was giving me a funny look but didn't say anything as they walked out the door.
It got to be later and my mom went to bed hours ago, while I was up watching some tv, when they came walking back in. I could tell they both had a few drinks but it seemed Sis had a bit more then Betty. They both came in and flopped into chairs and Dorene pushed her recliner back. I looked over and her legs were apart enough and her dress was high enough, to know what her thong looked like.
I turned and looked at Betty and I knew, she knew, where I was looking. She just smiled at me, as she took one finger and slowly ran it up and down her body, as if she was tracing it.
"Me and Dorene have been talking tonight."
"Well, that's nice."
"Want to know what we talked about?"
"I don't know, but go ahead and tell me."
"Well, when I went up to get her, I walked in on her, just as she got out of the shower, and still in her birthday suit."
"Lucky you."
"Yes, it was! She tried to cover up something but she was too late."
"Okay, so what was it?"
"Well, on her body it said Jim Slut!"
"I wonder who the hell that is?"
"After a couple of drinks, I found out it's you!"
"Wow, that's crazy story."
She stood, went into the bathroom, and was in there for a bit of time. I was wondering if she was okay, when she came back out and sat back down across from me. She went back to running her finger and tracing her body again.
