Nellie had finished stripping when she realized there was a second bed in the room, and it was occupied.
They'd kept the lights off as they entered, so she hadn't noticed anything at first. Jim, her date to the party, had kissed her in the hallway. She'd bit his ear and pulled him into the first dark room she'd found, closing and locking the door behind them. In the darkness, she'd whispered that she was going to fuck him senseless. He had hastily stripped, and she'd pushed him onto the twin bed. But now, as she'd finished shedding her black lace bra, her hand bumped first into the edge of a mattress, and then, as she felt around, into someone's foot.
"Are you okay?" Jim whispered.
"There's someone here," Nellie whispered back.
"Shit," he said. "Should we leave?"
"Hold your horses," Nellie said. She paused for a moment. The person on the bed was breathing evenly, despite the interruptions. Nellie reached out gently. She felt a smooth leg, and she shook it. The girl's breathing stayed even.
"Let's turn on the lights," Nellie said.
"Are you sure?" Jim asked, but Nellie was already standing and walking to the switch.
In the light, Nellie could see that the girl on the bed was Yoriko, another member of Nellie's research program. She was sprawled facedown across the bed, with her limbs splayed out. Her shoes were still on and her skirt riding up her bare legs a bit. In her right hand, stretched up above her head, she held a pill bottle. Nellie leaned in close and examined it.
"Bad girl," Nellie said. "These pills are Xenipha. I had to take it for a while when I was stressed out during exams. You're not supposed to mix it with alcohol, or it knocks you out cold for hours."
"Ah," Jim said. "So...we could fuck next to her and she wouldn't wake up?"
Nellie found herself staring up Yoriko's skirt. Yoriko was demure and polite, with long black hair, and Nellie found herself wondering if her pussy reflected any of those characteristics. She could just make out the unconscious girl's leopard print panties. Yoriko's legs were spread wide, and Nellie could see the shape of her pussy and just a bit of her pubic hair peeking out.
She looked back at Jim. Obviously, he was distracted. Nellie's curly red hair flowed down over her shoulders, covering the tops of her full breasts. Her nipples peeked through, wantonly erect. Surrounding her pert nipples were a smattering of freckles. The freckles continued down her chest and belly, spilling out onto her hips and thighs. Her legs were slightly spread, revealing her coppery red bush and her open pussy lips. Jim's kisses, and her own wandering thoughts, had left her very wet. Either Jim could tell, or the sight of her was enough, because Jim's cock was ready for action. She looked at his frame - strong but not muscle-bound, with his cock jutting forth - standing next to Yoriko. A devious smile spread across her face.
"We could," Nellie said. "But I think we need to consider what's fair."
Jim frowned. "Yeah?"
"For example," Nellie said, "we're naked, but Yoriko here is still in her clothes. Is it fair for her to see us naked when we can't do the same?"
Jim raised an eyebrow. "She can't see us, though. You said she's out cold."
"Right," Nellie said, "but she has the opportunity to see us naked. I think we should have the same opportunity. Help me out."
Nellie pushed Yoriko onto her back and began stripping her. She began by sliding off Yoriko's boots and dropping them on the floor. Next, she peeled off her socks. After a moment of hesitation, Jim lifted Yoriko up. Nellie grabbed both her skirt and panties and slid them off smoothly.
Nellie positioned Yoriko's legs apart. Her legs were pale and shapely. She had a small bush, and her outer lips covered almost all of the rest of her pussy. Nellie glanced over at Jim, who was also staring as if mesmerized.
"Now her top," Nellie said. Nellie lifted Yoriko's hands up above her head, and Jim slid her shirt off. Her bra clasped in the front, and Nellie unfastened it and slipped it off as well.
Fully exposed, Yoriko was a beautiful sight. She was slender, her pale skin contrasted by her straight black hair. Her small breasts were capped by petite dark nipples. Despite the jostling, her pretty face remained expressionless, and her breathing stayed even.
"Oh, she's a cutie," Nellie said. She glanced at Jim, whose cock seemed to agree. "Don't you think so?"
Jim hesitated for a moment. "Yes," he said.
"You can touch her," Nellie said. "That would be fair. After all, she can touch you too if she likes."
Jim delicately placed a hand on Yoriko's side. He ran it across her smooth stomach, then up to her chest and onto her breast. Gently, he traced his finger around her nipple. Yoriko moaned quietly, and Jim took a step back.
"It's alright," Nellie said. "That was involuntary. She won't wake up, but she can't help but react when something feels good. Here, watch."
She leaned forward and took one of Yoriko's nipples into her mouth. She began sucking, and ran her tongue around Yoriko's dark areola. Then, when the nipple was hard, Nellie began to nibble. Yoriko moaned again, more loudly.
"You see?" Nellie said. She leaned across Yoriko, her breasts rubbing against the unconscious girl, and took Yoriko's other nipple into her mouth. It, too, began to respond. She lifted her head for a moment. "Why don't you try it?" she said, before continuing to lick. "We can both take care of her. That would be fair."
Jim hesitated for a moment, as if at war with himself. His eyes shifted between Nellie, who was awake and willing, and Yoriko, passed out on the bed. Nellie narrowed her eyes, as if daring Jim to join her. He stepped forward and leaned over the bed.
"You're blocking her breasts, though," Jim said.
Nellie smiled. "I bet she needs attention somewhere else."
Jim needed no further prompting. Nellie watched as he lowered himself between Yoriko's legs. He kissed her thighs, one and then the other, moving ever closer to her exposed pussy. He pressed his lips against hers, and she moaned again.
Jim began to explore, his tongue venturing between Yoriko's lips and inside her. He licked up and down, flicking her clitoris with his tongue. He sucked on her lips, drawing them into his mouth. She moaned with each breath, a slow rhythm that began to pick up speed.
"Look at him," Nellie whispered in Yoriko's ear. "Well, you can't. But you can feel him, can't you. As oblivious as you are, your body loves this."
Yoriko moaned.
"And you can't do anything about it, can you," Nellie went on. She began to gently stroke herself. "I can make him do whatever I want to you. And you will just moan and take it."
"Ohhhh..." Yoriko said.
Jim was moving faster now, his head moving in little circles as he licked and sucked at Yoriko's pussy. Her wetness was dripping out of her.
"Oh," Yoriko said.
"Yes?" Nellie said.
"Oh," Yoriko went on. "Oh...oh...OH...OHHHHHH!"
Yoriko's limbs twitched slightly. Jim could feel her pussy contracting against his tongue, clutching down and releasing over and over again.
"Ohhhhhhh..." Yoriko moaned as her orgasm finished.
"Oh, that was lovely," Nellie said with an earnest smile.
Jim finally pulled his face away from Yoriko's pussy. It was wet from her climax.
"Well, that was nice," Nellie said, "but I don't think it was fair."
"How so?" Jim asked.
"Well, you gave her an orgasm," Nelly reasoned, "but she hasn't given you an orgasm." She pointed at his cock. "Clearly, you need one too."
Jim nodded. "I could cum on her boobs," he said, "or rub up against her."
