A Little Test for 18

Yamcha had an idea. Worst case, nothing would happen and he could just destroy the evidence, but 18 was here. The perfect first participant. And he needed proof that this thing worked.

"Once 18 sees Yamcha again, she will excuse herself and go to the restroom. Once there, she will masturbate to the thought of Yamcha" he wrote, giggling like a child the whole time.

"If this works it's gonna be awesome!" he boomed as he rushed back downstairs.

"So, when's everyone else supposed to show up?" he inquired. As he did, 18 immediately stood.

"No idea" she huffed "Keep an eye on Marron for me, alright Krillin?" she said, as she walked off towards where Yamcha had just came from.

Minutes passed, with Yamcha and Krillin making small talk as Roshi, presumably, was in the kitchen with his new bottle.

"Hm... 18's taking her time..." Krillin said, looking over the back of the couch towards the hall.

"Yeah. Weird. Want me to check on her?" Yamcha asked.

"Uh... you?"

"Well, you gotta watch Marron right?"

Krillin shrugged

"Yeah sure. Just make sure she's alive in there" he joked.

Yamcha made his way to the bathroom again, placing his ear against the door. And there, he heard a muffled voice.

"Oh.... oh.... oh... Y-Yamcha... oh.... ooooh...." 18 quietly moaned from the restroom, trying her best to keep quiet, it seemed.

Yamcha pumped his fist in victory. It worked!

So many options had just opened thanks to this book. The hot blonde Android on the other side of the door, his ex, Bulma, Goku's wife, Chi-Chi, and many many more girls could all be his!

"Ooooooh...." 18 moaned again, before he heard her clear her throat, and the rustling as she stood and put her pants back on.

He could take advantage of this and write something more for 18... or just wait until he had another, and possibly better, opportunity.
