Bedtime.

"Oh wait," Hane blurted out, stopping in her tracks before pressing the elevator button to her floor.

"What's wrong?" Jonathan asked.

"Just hold the door while I go grab something!" she shouted while she jogged out.

Jonathan could not tear his eyes away from her ass while she hurriedly left the elevator car back to the medical bay. While he waited for her to return he wondered what her large cleavage would look like when she ran, however, he did not need to imagine when Hane jogged back with a portable handheld EEG machine and headband.

"Sorry, I forgot to get this for you," she panted with her breasts, which were barely covered by her low v-neck t-shirt, rising up and down with each breath.

"We need to get you into more cardio training," Jonathan noted.

"Yeah..." she blushed with a smile, finally noticing he was staring at her cleavage.

"So what's that for?" he wondered, averting his eyes to the devices in her hands.

"We should monitor you while you sleep," she replied. "The headband won't be as intrusive while you sleep like the electrodes would be."

"Sure," he nodded as he hit the elevator button for the ninth floor.

The trip down felt longer to Hane than it actually was. She tried to assure herself she was just being professional, going to Jonathan's quarters was part of monitoring the effects of lack of sleep, however, she could not get the thoughts out of her mind that she should take advantage of the situation of being alone with him, an opportunity she would not have very often with thirteen other women around in the enclosed space of the underground facility. She nervously glanced over at him while he stared up at the floor display, only to embarrassingly turn away when he felt her eyes on him and looked down at her with a warm smile.

The elevator stopped on the ninth floor and Jonathan held the door open for Hane to leave the elevator car first.

"Wow, you get the entire floor to yourself!" she said, looking around the empty floor.

"I guess it could be a bit lonely being the only one here," he shrugged while he led her to his quarters, "but I'm rarely down here."

"It's very spartan," Hane noted, looking around the room and noticing Jonathan did not have any personal memorabilia like photos.

"Like I said, I won't spend much time here since I barely sleep," he stated, pulling his t-shirt over his head to reveal his muscular torso.

"But you will tonight," Hane replied, unable to turn her eyes away from his body. "You should sleep at least eight hours."

"Doctor's orders?" he smirked as he removed his sweat pants. Hane could not avoid seeing the large bulge in his underwear.

"Yes," she nodded, motioning to him to lean forward so she could place the EEG headband around his head. She turned on the portable EEG and set it on the nightstand next to the bed.

"Good night, Hane," he smiled as he laid down on his bed.

"Good night, Jon," she smiled back, however, for a moment she hesitated to decide to do something that was against her professional and personal ethics and standards. Surprising even herself, Hane leaned down to kiss him.

Jonathan, despite all his Navy SEAL training, was caught off guard by her kiss. He had thought when she had "inadvertently" pressed her ample breasts against his face it was just a tease but the kiss was quite deliberate and seemingly out of Hane's character of remaining professional throughout the preparation for the project.

"Um, Hane..." he muttered when she finally broke their kiss.

She blushed and bit her lower lip, glancing over at the portable EEG machine. "I just wanted to test your reaction," she stammered, "...for the EEG test..."

"Okay..." Jonathan did not require his SEAL training to know she was lying.

Hane realized that he did not buy her explanation but since she had crossed the line she decided to completely step over it.

"Hane!" Jonathan gasped when she pulled her t-shirt over her head, freeing her huge braless tits. He could not tear eyes off of her magnificent breasts and their large areola and pencil eraser-like nipples, even while she pulled down her sweatpants and panties.

"This is for science," she grinned, staring down at the enormous tent pitched in his underwear.

"Hane..." he protested but did not stop her when she pulled down his boxer briefs to release his raging erection from its confines. He let out a low groan when he felt her delicate feminine hands grasp his thick veiny shaft.

The neuroscientist held his penis to curiously examine its girth and weight — it had been a long time she touched one let alone have one inside of her. For a brief moment she toyed with the idea of giving him a blowjob but she realized that she did not much experience doing so and she could not remember the last time she tried it.

"Hane, we shouldn't do this..." Jonathan warned while she climbed up onto the bed.

"We're both consenting adults, Jon," she purred, looking down at his hard cock, "and it looks like you are quite willing..."

He had barely gotten over his regret for having sex with the triplets earlier that morning but now he was about to have sex with a fourth member of the crew — the project co-lead no less! — before the first day of the project was over.

Hane sensed his hesitation. "Don't you want to have sex with me?"
