It was his final year of college, and he and his friends had decided to go on one last vacation to celebrate. They had booked a week long getaway at a...n all inclusive resort, and were ready to end the school year with a bang."Man, that is soooommme view" Kevin exclaimed from the seat next to Andy. Andy and Kevin had been friends since high school, and Andy couldn't imagine going on a trip like this without him. They were both on the school track and field team, and had the figures to show for. .."Kira purred, "mmm ... mmmm ... mmmmmm..." I could hear her slurping as she applied suction. Her lips were wet with drool, my son's cock slippery and pulsing."When he cums, Kira, you can keep him inside if you want ... that's what I enjoy. Just concentrate on breathing ... breathe ... that's it." Kira bobbed in long motions, my son's penis becoming over-engorged. "Do it, Dex," I told my son, "fill her mouth." Kira braced herself by making her movements more shallow and tightening her lips.. .I ran my hand along the rough wooden post. It was cemented into the ground, sturdy as my cock was. My fingers danced up the chain from the eye hook in the timber and onto her polished black leather collar.She was on her feet, but still doubled over due to the post's height. Usually they slept sitting against the beam.I tugged on her arms trying to part them from her ribs. As always they were secure. With a now liquid motion I checked all her bonds. Hammerlock? Tight. Head harness? Tight. Ring. I turned her back kissed at back of her neck and ear lobes and started licking it. She started to caressing which indicated that she is turned on. Then I turned her again then kissed her neck for which she moaned ahh ahh and then we went for smooching where we exchanged our saliva and had a deep tongue fight. We had cola nearby us, we had in our mouth and exchanged through our lips. This time she was very high.Then I encircled her erected nipple with my tongue and sucked it and pressed her.
