Magical Sex Potion

"Oh, Bridget," he moaned.

"I'm Brenda, not Bridget. Why settle for one of these girls when you can have two Briswells? Double the pleasure, double the fun. Double the orgasms when you fuck a Briswell in the bum!" she replied. Her short blonde hair fell over her face as she flung her head forward and back, gnashing her teeth and squealing as she tensed before cumming on him.

Melvin shut his eyes and said, "Oh, yes, Brenda."

"I'm Bridget, not Brenda," the reply came, and Melvin opened his eyes to see Bridget pushing away her twin while she plunged herself on Melvin's cock. "My turn to get off on you. Now, did she already give you the rhyme about double the fun and the bum stuff? I mean, duh! Choose us!"

She held Melvin tighter than the others while she made love to him, her breaths shivery gasps of joy as she slowly slid up and down on his cock, her pussy tight and moist over his rock hard manhood. Melvin appreciated the change of pace and thought he might even be close to cumming when Bridget came with a muffled gasp, her head buried in his shoulder. Melvin blinked, and Bridget was suddenly replaced by Shelly Stone.

"Sorry, just had to give you a try. Watching isn't all I'm good at," Shelly explained as she started to fuck him, much faster than Bridget. The new pace completely threw off Melvin's impending orgasm, and he had to begin from scratch. Shelly's brown pigtails bounced up and down, and she buried Melvin's face in her small but perky breasts. Melvin latched onto Shelly's pigtails as if they were handlebars on a bike and steered her at a suitable speed by pulling them up and down.

It didn't seem Shelly had been on for very long when Red took her place. Red was skinner, as thin as a rain, and her pussy was the tightest of the bunch, almost painful for Melvin to enter. Once he was in, he was sure he wouldn't be able to last very long, her pussy milking him and his face covered in a bundle of Red's dyed hair.

"Fuck, fuck, fuck, fuck," Red simply repeated in sharp, jagged breaths.

The next moment, Red was gone, and then came Courtney.

Perfect Courtney, dimples forming at the corners of her smile, her face flushed, her freckles peppering her nose and cheeks, her naturally red hair shimmering in the light.
