“So I’ve been working on a spell…” Maddie began, looking up at him from their snuggled position on the couch.

“Oh no,” her tall and lanky friend-with-benefits teased. “I’m assuming you want to cast it on me.”

Madeline’s eyes lit up. “It’s supposed to make your cum even better.”

“As if you dislike it now,” Scott replied, laughing.

“Shhhhh. What’s the harm? I get an even better end to sucking you off, you get a hot and sexy witch that’s even more inclined to give you head. We both win.”

Scott smiled, and contemplated for a bit. “Alright, sure.”

She grinned like a cheshire cat. Sliding from the sofa, Maddie dragged her tits down Scott’s legs, making certain he was hard. She quickly undid the button and zipper on his jeans and pulled those down with his boxers. Scott’s fat dick flopped hot, hard and thick, and Maddie deftly caught the head in her mouth.The witch pumped her thick lips up and down the shaft for a second and ran her tongue under the head.

“Maddie..?” Scott asked. “The spell?”

She let him out with a faint pop. “Sorry,” she said, giggling. “I just get into it sometimes…” Madeline pulled his cock and balls free of his clothes, then put a hand on either one of his testicles. She pulled one hand back and snapped her fingers, then replaced it. The magic flowed from her into him, and in seconds, his balls were expanding rapidly. Starting around the size of her fists, they engorged quickly into two grapefruit-sized cum-machines.

Maddie rubbed her hands over them, smiling from ear to ear. Scott looked down, eyes wide. “Jesus, Maddie, they’re huge!”

“Huh?” Maddie slowly came out of her reverie. “Oh, yeah, I guess. Too big? I can shrink them again, probably.”

“N-no, it’s okay,” he said.

“Well then,” Maddie purred. “Gotta find out if the main portion of the spell was a success.” She smirked before enveloping his cock head with her mouth again. Tiny gurgles sounded from her as Maddie bobbed her head and slowly worked herself further down on his shaft. She twisted around on him as she sucked him off, making sure to work her tongue in just the ways she knew drove him wild.

Precum dribbled into her mouth as Maddie came up to massage the head with her lips, and immediately she could tell it was different- better. The taste, only a slight tease compared to what was waiting for her at the end of this, was like every flavor she loved put together. It only made her redouble her efforts, and she grabbed the shaft in both hands to steady it as she picked up the pace. Most of Scott’s dick was covered in her saliva at this point, and she moved one hand from his length of cradle one of his balls, tenderly holding it.

If Scott’s pre tastes this good, Maddie thought, then I can’t wait for him to nut. These super-sized balls are gonna have so much…

Maddie braced herself and resolved to take him all into her mouth and throat, humming gently to ease him in and suppress any vestige of a gag reflex. Inch by exultant inch, Maddie was increasingly wrapped up in sucking him, even more than usual. The witch united her lips with his pelvis, and pressed her face against his skin. She could hear his balls churning, producing all that delicious, salty cum that she craved.

She stayed there for a second, mesmerized by the sounds of his testicles, and brought her hands up to massage them. Maddie wanted nothing more than for them to produce an absurd amount, more than she could swallow, so she could let some decorate her face and her sweater-clad boobs. She slowly, torturously, slid her lips back up his length, running her tongue around it and twisting again. Maddie moaned, and it was all he could take.

With just the head in her mouth, Scott’s floodgates opened and basted the back of Maddie’s throat in cum. The overpowering taste made her eyes roll back in her head, and she began to feel kinda dizzy, but she kept her seal on him, now not wanting to let a single drop go astray. More, more, she thought, using her hands to jerk him off. There was no end to his cum, and she couldn’t complain- it only seemed to get better the more she got.

Finally, his fountain of semen slowed, and Maddie could breathe again between blasts of cum. With the last ropes deposited down her throat, the witch leaned back, finally slipping his cock out of her mouth. The light-headedness only seemed to intensify as she stood, and Maddie stumbled and twirled onto the couch, dazedly looking up at the ceiling.

“You okay, Mads?” he asked, pulling his clothes back on.

Maddie giggled a little. “Yeah, that was just… really good. Really fucking good.”
