Lexter's Lab Again...

Lexter had found out that the Mind Watch was working somewhat well, but currently required consistent use to properly work on someone. He had been testing frequently on Lina, who was currently giving him his first titjob. Finally, weeks of making her do increasingly lewd actions had paid off.

"Grk, cumming!" Lexter cried as Lina's boobs moved up and down his cock, cum splurted out from between her breasts as she milked him hard.

"Feel all better?" Lina asked, thinking that she was simply helping her stepson relieve some stress. Well technically she was, but his Mind Watch was making it seem a lot more safe for work from her perspective... despite the globs of cum now pooling between her massive breasts.

"Yep, thanks Lina!" Lexter stood up and cleaned his dick with a paper towel, before passing it over to Lina, "Clean yourself up will ya? Oh and by the way, you'll find yourself enjoying the smell of this more and more, and be curious what it tastes like. In a positive way of course."

"You got it!" Lina replied.

Lexter was making suggestions that would slowly work its way into Lina's mind. His mind control worked a lot differently from Director Groan's Hypnosis App, which rendered anyone with the right conditions into a mindless drone. Lexter's Mind Watch allowed him to implant suggestions that overrode a person's common sense, which would only trigger when the Mind Watch's effect was active around them. Once Lexter switched it off, Lina would forget everything that happened and any suggestions or whatnot wouldn't carry over to her normal state.

He had tested this extensively to make sure he wasn't mistaken, and now it was really paying off with the fun he was able to have. Ashley and her friends will being coming over soon, Lexter thought to himself excitedly. He couldn't wait to try the device properly on them now.

"Hey Lexter!!!" Sophie greeted.

The other two waved and said hi to Lexter as well.

"How is the progress looking on the watch?" Sarah asked.

"It's all finished! We're going to run some tests today!' Lexter exclaimed.

"That's great Lexter!" Ashley smiled. Lexter wanted to switch on the Mind Watch then and there... wait a minute, what was stopping him?

He switched it on and got to work immediately. The last few visits, Lexter had been suggesting to them that it was completely normal and not even a little bit out of the ordinary to make a friend cum, especially if it was to thank that friend. Stuff like kissing, groping, and all sorts of perverted stuff, were actually just things between friends.

"Before we test the device..." Lexter lied to the already hypnotized women, "Could you guys thank me properly for doing the work?"

"Oh, right... I almost forgot how to..." Ashley said, questioning her mind a bit. It was perfectly logical in this world to make your friend cum as thanks... but why did something feel a bit off?

"I'll go first!" Sophie chimed, running up to Lexter and giving him a sloppy kiss that evolved into a full wet making out involving their tongues.

"We really appreciate the help Lexter," Sarah added as she began massaging his crotch as she pulled up her shirt to offer him her tits to squeeze.

"Ashley, aren't you going to thank Lexter?" Sophie broke away from the kissing to ask, giving Sarah an opening to start making out with him.

"Ah! Right!" Ashley replied and knelt in front of his pants and pulled it down. She took his dick in her hand and begun stroking it slowly. It was strange that even though the logic made sense, everything about doing this felt foreign to her. There was zero muscle memory of her doing this, so it felt almost awkward stroking her friend's penis with her hand.

"Guys you didn't have to go this far for me," Lexter acted as a trail of saliva lingered between his and Sarah's lips, "I just made this device to help you guys out."

"Lexter, that was just the bare minimum!" Sophie jokingly chastised him, "We're not leaving till you cum today, and that's a promise!"

"Well, if you girls say so," Lexter shrugged, having the time of his life.

He resumed making out with Sophie, shuddering as he began to feel the hot tongue of Sarah and Ashley working together on two sides of his cock. He gripped Sophie's boobs for dear life as he could barely withstand the pleasure, and a while later he exploded.

"Gaaugh!" he cried as he shot ropes of cum all over his laboratory floor from the pleasure of Sarah and Ashley's tongues.

"Now we're even," Sarah grinned.

"Yes we are..." Lexter sighed happily.

...

Lexter handed Sarah the device that he called the "Anti-Mind Watch".

"You don't really have to be careful when using it," Lexter explained, "All it does it PREVENT mind control, so overusing it won't do anything. But you do have to keep an eye on the battery though."

"Gotcha," Sarah nodded as she took the watch and looked at it. She felt a weird taste in her mouth, but figured that might be just a piece of her breakfast that got stuck in her teeth.

"I feel a bit strange..." Ashley said, "Like I was doing something, but forgot what I was doing."

"Hah! Happens to me all the time!" Sophie acknowledged, "It's worse when I enter a room. One time I entered a room and forgot what I was doing, but thankfully Ralph reminded me it was to help him clean his pants! He made me rub it clean while he was still wearing it though..."

"Yeah... I'll go talk to Ralph about that later..." Sarah cracked her knuckles.

"It was probably just deja vu or something," Ashley said as the three left Lexter's lab.

Lexter watched the three leave, mostly fixated at their asses swaying as they walked, but also realizing that the effect didn't work as well on Ashley.

"I'll need to think of something for her specifically," Lexter thought aloud as he looked at his Mind Watch. He would think of a way to deal with any weaknesses in the design while he tested with Lina more. He turned back to his desk and started tinkering again.
