Rail her against the railing

As the ship slowly steamed away from the harbour, still connected to the tug boats, Mike kept fucking Grace from behind, her body bend over the railing. Here and there there was a whistle from below and he was certain the cheating slut would feel super embarrassed but he didn't care right now. As he enjoyed pounding her pussy, he reached around her body and gave both tits a good squeeze.

Grace groaned as he pulled a bit on her tits as if they were just toys. Then, Mike was still fucking her, the tug boats seemed to have done their jobs and departed from the ship.

"Hey," Mike told Grace, "don't be shy. Give the guys a wave as a goodbye." He gave her pale ass a slap and Grace gave them a little wave. Mike slapped her a bit more. "A bit more drive, slut. And throw them some kisses."

Grave finally waved and a moment later the captain of the tug boat responded with a blow of the ship's whistle, before pulling away from the cruise ship.

Mike returned to groping Grace's tits, using them as a handle as he kept fucking her. He had noticed that some of the other guests stopped for a moment to get a good look at Grace being bent over the railing. "Seems you catching some attention," he told her and pulled her close, before shooting a load of cum into her hot pussy. "Bet you gonna be popular."

Then he pulled his cock out and grabbed Grace's hand, pulling her over to some of the sun chairs. "Put those tits into use," he said and laid down. Grace hesitated a moment. "Or do you want to be fucked like her?" he said and pointed over to Freya, who by now was in a face-down, ass-up position on the desk chair. Her face was coated in cum and her eyes looked a bit vacant while some guys had fun fucking double fucking her ass. Only a few groaning sounds from the young Brit showed that she hadn't fully passed out.

Grace also looked at Freya and quickly pressed her big tits around Mike's cock, sliding them up and down.
