Jump right in!

"Alright, you're the boss, Liz," you tell her as you move up to her and grab the throbbing cock. It oozes precum after only a few rubs. You spread it around her shaft with your other hand. You manage to keep it flowing as you sneak some away behind you and inside your sweat shorts. She really keeps it flowing, and soon you realize you don't need to apply it to your crack directly as it has the ass of your shorts soaked with the slimey substance.

You jump forward onto her without warning. Your arms barely reach past her jutting chest to her shoulders, but you get your legs around her waist easily. She stumbles a second but regains her balance as you thought she would. She has gotta have some strong muscles to hold up that weight in the front. She smiles wider as she holds you without visible effort. You lower yourself a bit until her shaft rests in your precum-soaked cotton-clad buttcrack. Then you slide back and forth on it easily. She half giggles and half moans at your game. Her knees get a little wobbly.

"Are you alright?" you ask her.

"Yeah, it's just really kinky is all. I'm afraid I'm making a mess of your hardwood floor, a-and it's gonna get worse...!" Liz tenses up as you continue to rub her shaft with your asscleavage. You hear splishing sounds from behind you. She slowly lowers you two to the floor after you hear the wet sounds stop. You look to see a rather large fan-shaped puddle behind you.

You turn your attention to the now wrinkled watermellons resting under you. You rub one lightly as you dismount Liz, and rub the other until they soon regain their smooth taut appearance. They are not hard like yours, but more like waterballoons.

"See, they refill in under 15 minutes," Liz tells you. She stands upright again and strikes a pose. "Sex Captain Liz, ready for action again!"
