When the four of us recovered from our orgasmic bliss, Melody told Terry that she was very good at eating pussy. Terry replied, "Thanks, I get a bit of practice now and again, Kevin and I have a friend that joins us sometimes."
Sherry looked surprised, "You never told me about that." she exclaimed. "Who is it?"
Terry said, "I won't tell, but if you are around next time she comes to vist, maybe we can all play."
I was listening to all this and learning new things about my sisters, and my girlfriend.
Mel spun around and snuggled up to me kissing my cheek, then my ear. She whispered a question that I thought I'd never hear, "Would it be ok if I fuck your sisters?"
I looked at her, and whispered back to her that it was a bit late for asking. She said, "I know, but that was a heat of the moment kinda thing, and I didn't really do anything but lay there. I want to be more involved."
I looked at her and said that this was all kind of weird. She asked if she let me do more, could she do more. I was trying as hard as I could to not seem too eager. From the moment I saw Sherry sucking my cock, there was nothing I wanted more than to lick her, and her twin. To slide my prick into thier wet cunts, and have them take turns fucking me till I died or my cock fell off.
Sherry and Terry had been talking to each other in much the same was as Mel and I had been, I asked what they were talking about, and Terry replied, "I think the same thing you guys were, and yes, we want to spend the rest of the weekend fucking both of you, each of you, and each other."
Melody actually squealed in delight. She got up onto her knees, went to the girls, and kissed each one, a bit more than just a peck. She looked at Terry asd said, "Show me how." while looking at Sherry's pussy.
Sherry smiled and spread her legs, inviting her sister and my girlfriend to lick her already very wet pussy. Mel and Terry leaned in, Terry in the more prominent position. She kissed the inside of Sherry's thigh, then turned to Mel nodding to Sherry's other thigh. Mel leaned in and kissed her and slid her tongue down towards her pussy.
