Engie had to diplomacise in order to reduce her libido as low as she would let it, and her stamina, too. Additionally, he recommended that they tune her fine memory down a bit, that she would be able to find interest in the same thing twice, or as many times as she chose. By the end, Engineer was reasonably sure she was a more balanced individual, and, while maybe not any better a person, certainly better at being a person.
Later that night, Scout and Mina had another round. She didn't feel the same about it. She knew Scout was happy, but she wanted more satisfaction than she was getting. After Scout went to bed, she got to modifying her files again.
Mina liked the fine memory loss, it preserved the interest in everyday life. But she decided that her libido had been too low. It was measured as a scale of decimals in between 0 and 1. She decided to add 5 on the 3rd decimal place. She tuned her rough memory just a smidge lower, all the better for doing it again. And lastly, she made her butt, nipples, lips, and tongue all erogenous zones.
Mina was already masturbating minutes after she was done, but found her hand to no longer be any use but for teasing. She looked around for something to pleasure herself with, and her eyes settled on the wrench.
She tried it slowly at first, not knowing what could happen if she tried to shove it all the way in. But the further in she put it, the better it felt, and she found herself putting it in deeper and deeper.
Its handle was just underneath two feet long, but she fit more than a foot of it inside, and kept trying to shove it deeper until it hurt.
Mina knew her systems wouldn't send off pain signals until something was threatened with damage, but she kept ramming the wrench in there, right through the pain. She dripped lubricant all down the wrench's handle, and was satisfied, if only for the moment.
She decided to change up some hardware. When she cut open some of the stitching, and removed the soft false flesh packs, she noticed that due to well-organized wires, there was some room for addition. Mina grinned.
By the end of the night, she had added some appendages, and lengthed her vaginal hole until it reached her stomach, and made sure it could take some punishment before even starting to hurt. She smiled at her handiwork, and this time made sure to pick up the missing parts from the hardware store, so Engie didn't have to know a thing. Besides, he wouldn't count them again until the next day after tomorrow, so there wasn't any harm there. She put everything back, stitched herself up, and headed to the bunks.
Scout woke up to the greatest blowjob of his life. Mina looked at at him with a cute, innocuous expression. Down behind her, she had gotten the entirity of one of Scout's bats into her sopping cunt, which now leaked nontoxic, edible, slightly salty and sweet liquid lubricant.
She went up and down, very glad that she had made her mouth an erogenous zone. Scout sat up and held the back of her head, pushing her back and forth, up and down his dick, as she moved the bat faster than he could hump her mouth.
Scout came in her mouth, more than her mouth could hold, so she opened her mouth to show him, and swallowed, wiping a bit of it off of her chin. Scout sighed. "Wow. You're right.. damn, that is really hot." Mina smiled and lied down in Scout's bed to hold him until he fell asleep.
Once she was done there, it was time to go scout out new terrain. She had left a couple clean, well-secured holes in her stitching, so as to let her extra appendages out. She flicked it out. It looked like a silver snake that was belly on all sides, and whose head was stuck in the snake-hole.
Mina had made 4 of them, and there were 5 stitched holes, each inlaid with a large washer to help their shape, two on the backs of her shoulders, two above, and on either side of, her vagina, and one larger, stronger one just below her tailbone.
She snaked the two lower silver serpents out, and positioned them to spread her pussy lips. Her two upper snakes bound her hands together behind her back, and the largest snake went all the way into her cunt dry, drawing a sharp breath out of her. Mina moaned in joy as the ribbed thing went in and out.
Spy was watching. He wasn't surprised, after all, once she had been given a taste, she would never want to hold back. However, the tentacles, did startle him. He hadn't expected there to be enough room for that, let alone 5 of them. But there she was, hands bound behind her, ribbed snake inside of her. Mina came, screaming into the lab she thought was empty. Spy wanted a piece of her badly. Of course, he accomplished this the way only he would: He disguised as Scout, making sure it was red, and opened the doors to the lab.
When Mina heard the door open, she thought of who could have just walked in, and moaned louder over that. Spy put on his best Scout impression, a very good one, and asked "Hey, who's having fun without me?"
Mina looked over, and pulled the larger snake downward, so Scout would have some room above it. "Do you want to join?" Mina asked him in a sultry tone. "Aw man, now do I!"
Spy fit his dick into her vagina, pressing against the tentacle below him, and found it very pleasurable. His dick was rubbed from above and around by her still very tight vagina, and below, the ribbed tentacle did something to his dick that Spy had never done to it before.
Mina's shoulder tentacles grabbed Spy by the waist, and they kissed one another very closely. Their tongues danced in one another's mouthes, and Mina knew that this was a much better kiss than Scout had ever given her.
She reached for the back of his head while they kissed and fucked, and when she felt the string on the back of the mask, she pulled on a loose end, undoing the mask completely. She broke off the kiss and whispered to him, "If you don't tell, I won't tell. Deal?" Spy immediately knew he could be in trouble. However, he couldn't stand the thought of tarnishing his reputation as a professional man of professional interests.
"Deal." Spy felt something cold around his ankle. It snaked upwards, twisting twice under his pants about his calf and his thigh.
"I won't tell if you don't tell~" Mina singsonged as Spy was handled by the tentacles. They were already covered in lube from Mina, but the two lower ones wrapped about his cock, while his hands are bound by the top two, and his leg is lifted from him by the largest one, which was now far too close to Spy's ass.
Spy found himself helpless to get away as he received a bound handjob. They stroked in such a way that Spy was sure he would cum any moment.
One of them then secured itself around his dick, squeezing it tight. The other continued to pleasure his penis, while the larger one pulled his leg up so as to place him on his knees. It went into his ass. Mina fucked him doggystyle while keeping his dick red and swollen.
She pulled on it backward, making Spy tense up in pain. Letting her ribbed tentacle tail do the work in his anus, she climbed up on him, pulled him by the jaw towards her, and used what she had learned kissing already against him.
Spy had never felt so useless. Fucked in the ass by something larger than his own dick, forced into chastity, kissed by someonewho was taking the charge over him. Mina sucked on his ear, and whispered closely into it, in a breathy tone. "Do you want to cum? Go ahead. Tell me if you want to. Be honest." Mina giggled over his shoulder, and whispered into his other ear. "If you want to cum, promise you won't tell anyone. And if you do~.." The tentacle in his ass rams a little harder for emphasis.
Spy shouts in astonishment as the tentacle goes even deeper than before. "I want to cum! Let me g-OHGH!" Mina giggles again. "If you want to go, if you want to come.. Promise me." Spy curses under his breath, and shouts again, as the tentacle around his dick squeezes even harder. "Agh.. I promise! I promise, you fiend! I'll tell no-one, not a sould, just let go!"
Immediately, Mina slides down off his back, and climbs under him, to place her cunt over his dick. She lets go of it, and takes every bit of it into her pussy. The tentacle in his ass fills him up with lubricant, until he is leaking, and then all the serpent slink back into their holes. Mina gets up, stands over him, and speaks in a clear voice, "And you can't tell anyone. Good job in me, spook.. If you want, come back here sometime, we'll do it again!"
Spy immediately went to the bathroom and spilled out all the artificial cum she had left in there. After he was done, he had a long cry, and went back to sleep.
