As you run your hand up Molly's fluke it accidentally brushes against her moist vagina. You can feel her shiver against you, her breath rapidly becoming shallow and deep.
"Don't stop..." she pants, looking behind her into your eyes "Please don't stop."
Grabbing your hand from where it was frozen she guides it up to her clitoris rubbing your finger across it up and down up and down.
Shocked you take a deep breath, her scent filling your nostrils a distinctive tent in your trousers. "Molly, stop its the drugs they are doing something to you..."
Flipping around Molly pushes you onto your back her nipples peaking out of her soaking shirt. "It sure is." she says before locking you in a deep and passionate kiss.
Suddenly you don't feel as if any of this was wrong. reaching up you slide off her shirt revealing a pair of heavy heaving breasts. Taking one in your hand you gently squeeze an erect nipple between your thumb and forefinger, enticing a gasp of pleasure and a shiver of anticipation to course through Molly's body. Your other hand travels down, gently caressing her soft skin, finding her moist vagina again, where the fluke meets her torso. Thrusting your fingers into her she begins to buckle, eagerly rubbing herself against you.
Sliding out from beneath the mermaid you quickly strip off your pants revealing your large hard erection pulsing with desire. Your penis has never been this hard, stretching a good eight inches long. Leaning down you take one of her breasts into your mouth sucking on a nipple as you plunge your shaft into her waiting cleft.
You gasp in pleasure as you feel an electric energy course up from the wiggling and moaning Molly below you. Her vaginal muscles stroke and massage your penis as you thrust in and out of her, each thrust sending another jolt of energy into you. You feel your climax building, higher and higher your motions becoming faster and frantic as every fiber of your being begs for release.
Finally you can feel your climax shoot like lightning through your body, as you spill your seed into Molly. collapsing you nuzzle against her neck gently kissing her cheek.
