Ren fought against the flood of students pouring out of the university's chemistry department. After a short walk, he stepped into the materials engineering lab.
"Hey Sally," he called out.
A woman in a pristine lab coat looked up from the laptop sitting on her workbench and smiled at him. Her black hair and slightly darker skin belied her mixed heritage. Her American father fell in love with Sally's mother during a business trip to India. He brought her mother back to the States, and their daughter arrived about a year later. Sally wasn't her real name. Her mother insisted on naming her after her great-grandmother. Unfortunately, Americans had a hard time pronouncing it correctly. By middle school, she almost exclusively went by her nickname.
Ren discovered all of this while tutoring Sally for her computer sciences class. With his new experience under his belt, he now realized she had dropped some less-than-subtle hints that she might be interested in more than just tutoring. Sadly, they went right over his head at the time, and they settled into a companionable friendship.
The smile on his face faltered for a moment as he realized those romantic thoughts would make her susceptible to Xaal's blessing. He would have to make this quick.
That was going to be a problem, though. Sally's lab coat hid a shapely body, firm, apple-shaped ass, and perfectly sized breasts for her frame. Ren spent many nights after those tutoring sessions imagining her bent over as he pounded his cock into her from behind.
Now he was kicking himself for realizing that could have been a memory and not a fantasy.
"Everything okay, Ren?" she asked, giving him a worried look.
"It's all good, Sal. Some things in my life have changed recently, and I'm discovering how completely oblivious I was when it came to women."
Sally smirked, "Yes... yes, you were. Got yourself a girlfriend, I take it?" Ren didn't miss the hint of disappointment in her voice and mentally kicked himself again.
"Not quite. At least, I'm not sure if she wants to be my girlfriend."
"Friends with benefits?"
"No, we haven't slept together though she's made it clear she wants to. Wait, that's not what I came here for."
"Oh? So this isn't just you stopping in to say 'hi'?" asked Sally as she leaned back against the lab bench. The simple movement let her labcoat fall open making it framed her breasts nicely.
Ren glanced down and noted the two hard bumps poking against the inside of her shirt before wrenching his eyes back to hers. "Only partially, I met a woman who has an interesting condition. Her tongue is super rough, as in, cat tongue rough."
"That's weird," said Sally, standing up a little straighter.
"Very, but it has made it impossible for her to give... um... oral sex without hurting her partner."
Sally gave him a sidelong glance. "Are you just being a good wingman, or are you hoping she tests it out on you."
Ren blushed, "Uh... no comment."
Chuckling, Sally turned and bent over her computer. "So, what are your requirements?" she asked as her fingers flew over the keyboard. "Durable, since it needs to stand up to friction. Non-toxic and flexible since it goes on the tongue. Has she ever tried a dental dam like they use at the dentist's office? I heard sex workers use them to avoid direct contact during oral sex."
"I don't know, but that seems like such an obvious solution I imagine she has and it didn't work. She did mention that her tongue shreds condoms if that's any help."
"That means we need to add puncture and tear resistance." Sally tapped at her computer for a few seconds. "Any other requirements?"
"She mentioned that she wanted to taste her lover."
"Hmmm... That will be difficult with all the other conditions. Porosity doesn't play well with durability. However, I think I can get something to work. I'm guessing she wants it textured?" After a moment of silence, she looked back. "Ren?"
"Yes, what?" he said, blushing bright red. As Sally talked, Ren noticed her hips swaying back and forth as she typed away and quietly moved behind her for a better view of her luscious bottom. Unfortunately, her lab coat blocked most of his view, but he could still make out most of its shape. He quickly found himself entranced by the image in front of him.
Sally smiled. "About damn time you noticed my ass, but I need an answer. Does she want it textured?"
"I'm sure she does. Probably something a lot closer to a normal tongue."
"I'd be curious to meet this woman and see for myself just how rough her tongue is," she said before going back to tapping at her computer but not before flipping her labcoat up onto her back and giving Ren an unhindered view of her jean-clad rear.
The movement also wafted the scent of her arousal in his direction. While he had hardened slightly watching her ass sway, the smell of her excitement made his cock strain against the front of his pants.
After a bit more tapping while simultaneously teasing him and rubbing her thighs together, Sally stood up and turned around. Ren resisted the urge to hide his erection, and she rewarded him with a glance downward and a smile.
