We went to a restaurant and sat in a booth. They were on one side and I was on the other. They were very handsy. He even got her off right there in ...he booth. I was a third wheel. And I was okay with that. Barb was having guilt free incestual sex with Mark, Mark was cumming more than a guy had a right to. And I knew Barb and I would get back to a normal life in time. At least that was my hope.Eventually Mark finished the basement and it looked great. And he headed back to his real life. The flight took four and a half hours and ended in a gut wrenching landing on a runway that had been built in the sea, but there was no splash, no shouts of alarm, we'd made it!As the stewardess opened the doors the hot air hit us and we grinned at each other, we had four months of this to enjoy and we intended to enjoy every day of it.It was an hours taxi ride to the villa in Puerta Rica, a beautiful little holiday town built around a man made, horse shoe shaped beach, as we unloaded our cases. "Oh Yes" "Don't Stop" "YES!" "YES!" "YESSSSSSSSSS!" As she came I felt her nails dig into my back. I continued to thrust for a couple minutes before, "I'm going to cum." "Cum on my stomach, sweety." I pulled out and shot my load onto her stomach and bush. I took a deep breath and then leaned in and kissed her. We made out for a few more minutes. "That was amazing, Mrs. Williams." "I second that, sweety. I haven't been fucked like that in years." "I'm sorry to hear that." We sat next to each. Then they came near me and one grabbed my left boob and groped it tightly. i got up and said that's enough and started to go, one hugged me from behind and said please baby show us ur lovely soft boob. they implored, they held me tightly and kissed. they didnt let me go, so i said ok just once and said dont spit it out to any body. they promised and i undone 2 buttons from my uniform shirt and pulled out one boob from the bra and got it out and showed them, they gazed and praised. as i am fair.
