here's a story that was only on AFF, until now. basically a collection of oneshots with Ben and different girls as either himself or one of his aliens.

As the last of Charmcaster's rock monsters were destroyed by Ben Kevin and her rival Gwen, she knew the only option was to escape. However, she decided to take a prize with her, Ben Tennyson. She used a magic spell to teleport herself and Ben to an isolated location. As they landed, Ben broke free. He tried to use the Omnitrix, but it was stuck in recharge mode.

"Oh, now of all times?" Ben screamed at his watch.

However, before he could bang it, Charmcaster used her energy rope to bind his arms and legs to the ground.

"Now, your cousin and her boyfriend are gonna be here any minute," she said. "So how about you just sit back, and let me have some fun with you before you go?"

She didn't give him time to answer before she slammed her lips against his. He hadn't even gotten past holding hands with Julie yet. He jerked his head, making her look at him confused.

"I've got a girlfriend," he stated.

"Oh, I see. Well, don't worry. I'm just looking for some release. Now, just pretend I'm your girlfriend and enjoy this."

Charmcaster started licking him into the crook of his neck, and slowly got to his groin. She took the zipper in her mouth, and pulled his pants down. Then she grabbed the elastic of his Sumo Slammers boxers, and pulled them down. The 10" hard meat stick between his legs surprised her.

"Wow, Ben 10 has a 10" long cock. Jackpot."

She then took Ben's huge cock into her mouth, and started blowing him. She made him moan in pleasure, causing him to unconsciously buck his hips. This continued for four minutes before he came down her throat. She kept it up, drinking up all his semen.

The two of them would've continued, but they heard trees falling down.

"Oh, you have got to be kidding me. I'll be sure to finish things with you some other time."

She flashed away, and the energy shackles disappear. Moments later, Ben saw Kevin and Gwen.

"Yo, Tennyson, what-?" Kevin started until he saw Ben's cock. "Might wanna pull your pants and boxers up."

Ben looked down, and pulled his pants up. They went with Gwen, and Ben thought about those last words she said to him.

"I hope it's not too soon," he whispered to himself just enough so no one heard him.
