Let's check in with Mark.

After pulling his little trick, Mark decided to go to the car and wait. He didn't know how quickly Grink and Jen would affect him and he wanted to stay himself as much as possible. He figured he'd already suffered a little bit of transformation just from their brief contact.

He waited twenty minutes in the car just to be certain that Grink's transformation was complete. He assumed that Grink's ideal Jen's ideal Grink would just be a more helpful version of the same guy but he couldn't be sure. He needed to be ready for anything, he decided. He walked around to the back, popped the trunk, and grabbed the tire iron.

Mark took the same route across the yard to the open bedroom window. Crouching beneath it, he strained to hear what was going on inside. He heard Jen talking to Grink.

"...don't get why you would even do it. The shit makes you sick as hell, and for what? Some kind of spiritual experience?" She giggled a little then continued. "I know, right? I'm not smoking the shit to learn, I'm smoking it to have fun. As far as I'm concerned the religious nuts can have their peyote. If I'm gonna trip balls I wanna enjoy it. Am I right?" She coughed harshly, which turned into a laugh.

Jen seemed to be talking to herself. "Correct as always. Man, this shit hits hard." Mark decided to risk a look through the window, and almost fell backwards in surprise. Jen lay sprawled out on the bed, smoking a joint. Perpendicular to her, with her head resting on Jen's chest was, well, Jen. At least someone like her. This Jen was definitely porn-ier, with cartoonishly large breasts, wide hips, and plump lips. It was like looking at Jen and a funhouse mirror reflection of her having a conversation.

The less sexed-up Jen noticed him. "Hey, it's Mark!" She broke out in a fit of giggling. "Oh, shit, Mark! You'll never believe what happened!"

The other Jen turned to look at him. She looked confused for a second, then smiled lazily. She tried very poorly to suppress a laugh. "Oh shit, is that the guy you were talking about? Why's he look like that?"

Jen number one snorted and turned to her. "Look like what?" They both had a belly laugh.

Mark climbed through the window, trying to process the scene before him. "Jen?" He turned to the other one. "Uh, Jen?" The Jens looked at each and broke out in giggles again. The Jen with the bigger tits spoke. "I'm not Jen, dude. I'm fucking Grink!" She snorted, suppressing another laugh. "Why do you think I'm Jen?"

The real Jen turned to her. "You look just fucking like me, you dumbass!" They laughed again. Mark was starting to get equal parts annoyed and aroused. He looked at Jen. "So that's your ideal partner right now?"

She grinned. "She's hot, right?" She took another drag on her joint and coughed harshly.

"Jesus, how much of this have you smoked?" He snatched the joint from her. She reacted way too slowly to keep it, then looked at her empty hand with bewilderment.

"Not much. Just that joint. Give it back!" She reached out her arm expectantly. Grink-Jen was watching this all play out with a vacant smile, clearly enjoying it.

"You smoked half a joint and it got you this stoned? Come on Jen, what's going on?" The girls side-eyed each other like they had a secret, then burst out in another belly laugh. Mark sighed in frustration.

As she caught her breath, Grink-Jen tried to explain. "That's not weed, dude. That's... that's fucking 2C-B!"

He stared at the joint in his hand. It had a really weird smell about it, and he noticed that the contents weren't the typical shade of green you'd get with bud. "What the hell is 2C-B?"

This of course caused another gale of laughter from the Jens. Original Jen finally managed to cough out a response. "Try it! It's awesome! Try it try it try it!"

He looked at the joint, feeling tempted. Wait, why was he tempted? That was ridiculous! Oh, shit.

He realized they had a triangle of influence. Everyone in the room was influencing each other. The only problem was that being roughly identical, the two girls had basically the same ideal image as each other. This was keeping his influence from really changing either of them, and they were both influencing him strongly. Hence him considering pretty strongly taking a pull off this tasty roach.

No! He gave the joint back to Jen (it'd be a shame to waste good 2C-B) and tried to concentrate. He needed to get the Jens somewhere where he could influence them one at a time. But to do that, he'd have to transport them. He didn't want to risk leaving either alone - who knows what might happen if they wandered away and fell under some stranger's influence. He had to think, dammit! The smell of weed was making his mouth water. He realized he had to get out of here before he got any less coherent.

"Ok, Jen, uh, Grink. Listen to me carefully. You need to stay in this house. You must absolutely not leave for any reason. I'm gonna go outside. Grink, where are your keys?" She grinned at him. "Where do you think?" This caused another belly laugh from original Jen.

"Just tell me where the fucking keys are!" She coughed and pointed to the living room. Good enough.

"Ok, girls, I'm gonna take the keys and I'm gonna lock you in this house. If you need something, you can call me or yell out the window. I'll be back very soon, and remember - do not go anywhere." Leaving them in a dazed stupor, Mark searched through the junk in the living room for the keys. Finding them on the coffee table, he went around the house and tried to make sure all of the exits were locked. They could be unlocked from the inside, of course, but he was hoping these two had smoked themselves stupid enough that trying to unlock the door would provide at least a minor obstacle.

He paused at the front door. Damn, he was really craving a smoke. He had to get out of here now. He left and locked the door behind him, and walked across the street to his Jeep. He was hoping a little time in there would reverse some of the changes and help clear his head.

Inside, Jen looked at Lady-Grink with a dopey smile. "What was that guy's problem?"
