As we waiting for the bus to go back to Ibiza Town we both sat on the step outside the café eating an ice cream. Anyone who looked would have been ab...e to see both my pussy and Jon’s dick and balls, though we never saw anyone staring at us. We had to stand up on that bus because of the number of people on it and at one point my sarong came un-done and started to fall down on its own. I let it get down to my waist before pulling it back up. The bus to San Antonio was better; I did what Jon. "You're such a slut, Sam!" I exclaimed sitting down on the couch next to her."Not as big of one as you, slut," Sam moaned out while still playing with herself."Ya, you're right, I am a pretty big slut," I said while I grabbed her hand out of her skirt and sucked off all the juices off of her finger."Mmm," was all she said, as she leaned in and gave me a kiss. We made out for another five minutes, undressed each other, and explored each others body with our hands like we had done so many times. Debra rolled into me and cuddled as she said, “Oh my God, Jane has the best pussy that I’ve ever had.”I said, “I thought the same thing earlier when her pussy fucked me with neither one of us even moving.”Debra asked, “So what’s the deal with you and Jane?”I told her all about my girlfriend Denise, her request for me to have sex with her sister, and how wonderful I found Jane to be in bed and the way that she obeyed my desires.I said, “Maybe I’m marrying the wrong sister.”Just then Jane sat up. .it ok Randy, we’ll just ’pretend we are boyfriend and girlfriend while we’re down here. No one will know and there’s nothing to see…go ahead and feel me, like a girlfriend…”)I gulped. Our ages were not that far apart and it was no problem to think of her as a girlfriend. I had only felt up a couple a girls so far, so I was getting as horny as mom was. I kept saying to my self that nobody could see us and would never know….she was like a girlfriend I was making out with. I started feeling her.
