Magical Sex Potion

"You're going to get caught in here," the logical portion of Melvin's mind said out loud. Tina's pink lips split open in a wide smile, and she shook her head.

"No, I got our waitress to lock the door. I told her she could watch," Tina replied and pushed the stall door open farther. Sitting on the bathroom counter with a look of anxious anticipation sat the waitress with the brown pigtails. The waitress shrugged, her hands outstretched as if to say, "I like to watch. What can I say?"

"Well, my head does kind of hurt. I'm not sure you can help that though," Melvin said, rubbing the bridge of his nose. It was a true statement; a lingering headache throbbed behind his eyes. Tina continued to stroke his hair. She stepped forward, her legs now straddling him. Her thighs were deliciously tanned, and Melvin could see a bit of pale white skin from where her shorts had pulled up her legs. Melvin was now close enough to Tina's white shorts to see her pink thong through them.

"Want me to kiss it, Uncle Melvin?" she offered. She licked her lips, her tongue poking through, spreading a trail of moist saliva along her mouth. She looked hungry and more than a little horny.

"You don't have to call me uncle. Technically, I'm not you're uncle anymore," Melvin said. His eyes were parallel to Tina's perky breasts, and he was having trouble keeping eye contact with her. His eyes kept wanting to dart down and examine the pink fabric of the tank top straining against Tina's mouthwatering mounds.

"Well, can I pretty please call ya uncle anyway?" Tina said, pulling the pencil out of her hair. Her blonde curls unspooled to her shoulders, bobbing cutely, and she shook her head, her hair twirling from side to side. She was gorgeous, no doubt about it. This kid had broken so many hearts in high school you couldn't count them all, and she was represented everything Abigail thought she saw in herself. Melvin felt the crotch of his pants tightening around him.

"Sure," Melvin said, the word coming out like a croak from his dry throat. Tina held him captivated with her dark blue eyes and bent over to kiss his forehead, strategically rubbing her tits in Melvin's face. Hot desire breathed fire into Melvin's stomach, but he still didn't feel right taking advantage of this bright young woman in the men's bathroom. He had baby-sat this girl for Christ's sake.

"Tina, you don't have to do this," Melvin said, pushing her just far enough away that his face wasn't being crushed by her boobs. He wanted to give her one last chance to back out if she wanted if only to put his own conscience at ease. His hands were on her tummy, and he was surprised at how hard her abs felt. Tina looked down at him with her dark blue eyes and giggled like a schoolgirl.

"Uncle Melvin, I'm a freshman in college now. Suckin' and fuckin' is kinda what I do," she said and sat her firm ass on Melvin's thighs, looking him straight in the eyes. She squirmed a little, enjoying the hardness that crept down one side of Melvin's leg. A quiet moan passed through his lips.

"Let me show you," she said, wrapped her hands around his head and pulled Melvin's mouth to hers.
