After that pleasurable and blissful night with one another Lube and Reuben became near inseparable. Always hanging out, talking with one another, going out on date/shopping runs. Teasing one another (mainly Lube's doing), and most importantly having sex with one another every night. With Lube looking up every known fetish and sex toy in the galaxy (Earth included) to ensure that him and Reuben would never run out of ideas or new thing to try. The only time the two experiments did decide to separate from one another is when they wanted to get gifts or toys for one another that they wished to be a surprise.

And as the two experiments began to test the waters with one another they started to get more ambitious and open with their sexual escapades. With all is this having started off a week after Lube and Reuben managed to reconcile with one another, it was midday, and Gantu had left in order capture a new experiment.

"Aw kitten~!" 625 cried out, as he could feel his lovers tails tighten around his twin gentalia. As they both sat in the super computer chair, close enough to the control panel for Reuben to dig his claws into it with unbridled love and lust.

"Close, beefcake?" Experiment 438 teased with a squeeze of his tails.

"Y-Yes! Keep it up!" Reuben confirmed,

"Of course dear." Lube replied with a coo. But before he could put his love out of his pent-up misery, both experiments suddenly saw the computer screen change as Hämsterviel showed up on the monitor. This caused Reuben and Lube to freeze for a moment, but as Lube says the desperate look in his lovers eyes he decided to continue.

Not wanting to deprive 625 of the release he so richly deserved, but at the same time experiment 438 wanted to watch his beloved squirm.

"Hello Gant—What are you doing here!?" Hämsterviel said, staring at Lube in disgust and hatred,

"Making people happy." Experiment 438 replied with a wag of his eyebrows despite the hurt feelings he got when the fuzzy criminal stared down at him like that.

"N-Not that you would know anything about it." Reuben added, holding back moans and whimpers, as he glared at Hämsterviel knowing exactly what he was thinking about Lube.

"As if I would need to do anything so….unsanitary. Now where's Gantu?" Hämsterviel said, looking as if he would gag at the thought of doing such things. However, his attention was soon garnered back towards the experiments as he heard Reuben let out a loud groan as his grip on the computer control panel tightened. "What's going on with—"

"Gantu is off catching an experiment, you might want to call him before he does something stupid." Lube said, interrupting the rodent alien before he could finish the sentence,

"Your right about that...he could be doing something stupid right now." The rodent alien said before the transmission came to an end and Reuben was finally given the relief he deserved. Without fear of Hämsterviel overhearing them 625 practically screamed until his orgasm faded and he collapsed onto the computers control panel.

"You feel better?" Lube asked,

"Very, we need to do that again sometime." Reuben tiredly said as he began to recover.

"Really you liked it that much?" Experiment 438 questioned, his eyes going wide in surprise,

"Yes….it made me feel dirty." Experiment 625 replied and Lube chuckled making a mental not of this.

And after about another week since that incident, Reuben and Lube finally received the results from their tests and saw that the tests had essentially been something to test their fertility and refractory period. Basically the test had said that Reuben and Lube were very fertile who their refractory period was very small allowing them to bounce back very quickly after sex. This resulted in Lube trying to test both his and Reuben's limits in order to see how much they could take before they had to stop. But Lube could never reach either of their limits, causing a lot more ideas and pleasurable nights to follow the couple into the years. So as the two grew up happy with one another, having to deal with more experiments, not getting involved in Gantu's job unless needed, and the Leroy incident.

Reuben and Lube eventually got engaged and followed Gantu as he finally got his original job and career back appearing to have his anger issues mellow out as a result. And as a means to celebrate Gantu's return and rise back to his preferred career Lube and Reuben of course had sex.

Forever lustful, happy, devoted and loving to one another no matter whoever or whatever got in their way.
