Of course!

"You want to test that theory?" Dean asked, running his hand across Marina's ass.

"Come share my tube," Marina said. Dean let go of his own tube and swam to her. "Get behind me, put your arms around me to hold on to the tube. Or you can hold on to me, instead."

Dean didn't need to be told twice, and immediately wrapped his arms around Marina, groping her tits through her swimsuit, under the water. He leaned forward and kissed her neck, making her moan softly.

"I've wanted you since we first met, you know. You were just so cute," Marina said quietly.

"I've wanted you too, baby." Dean continued to kiss Marina's neck, while holding her tight and grinding his hard cock against her soft, ample ass.

Marina let go of the tube with one hand in order to reach behind her and start stroking Dean's cock. Even though it was an awkward angle, Dean couldn't believe how amazing it felt. Her hands were tiny and soft, but she gripped him firmly without holding on too hard, as if she was determined to gently squeeze all of the cum out of him. If that's what her intentions were, she was doing a good job of it. Dean didn't take long to get to the edge.

"Marina, I'm gonna cum soon."

Marina dipped under the water, coming back up in the center of the tube, and leaving Dean on the outside, facing her. She wrapped her legs around him and pulled him close, before reaching down with one hand and sliding her swimsuit to the side, revealing her trimmed pussy.

"Put the head of your cock in my pussy, and jerk off into me."

Dean was dumbfounded for a moment. He never dreamed of getting a request like that, which made it even hotter. He obeyed her orders, sliding his cock out of his trunks, clumsily holding on to the tube with one hand. Marina kept her legs tightly around him so he could push into her. If he hadn't been so close to cumming, he wouldn't have been able to resist fucking her - she was incredibly tight and wet. He then quickly and firmly stroked his shaft, until he finally finished, blowing a warm load into Marina's pussy, where it soon started dripping back out. Dean made a mental note to do this again when he could get a good look at the results.

Marina let her swimsuit go, and unwrapped her legs from around Dean's body. She grinned. "Go catch your tube, now," She said to him. It had floated a good distance away, and Dean had to swim quickly to get it and bring it back to where Marina was now lounging on top of her tube in the sun.
