Might as well.

Eric nodded and Dani grunted and pushed him off. They looked to Kat, who shook her head. "No hints," she told them. "You've got to figure this one out yourselves."

The couple turned back to one another. "I still think your tits have to be involved," Eric said as he openly ogled them. "They're just so... good."

Dani blushed. "Stop staring! It's making me feel weird. So what do we do with them?"

"No idea," Eric replied. He was exercising all of his willpower to look her in the eye.

"Well, since it apparently involves your penis, maybe my vagina's part of it?"

"Eww!" Eric said, his eyes briefly dipping downward. "You pee out of that!"

She had started to massage his penis again. It was slowly returning to full mast. "And you pee out of this. Maybe you're supposed to... touch it? Like, touch it to my pussy?"

Eric frowned. He studied her bare snatch, thinking. "Do you think it would fit inside of it?"

Now Dani was grossed out. "What? Even if it did, why would I want your whole dick in there? That can't possibly be right."

Kat snickered and they both noticed. "Ok, that made Kat laugh. We're either on the right track or super wrong. Wanna give it a shot?"

She eyed his now-tumescent member doubtfully. "I guess..."

Dani positioned herself awkwardly across his midsection. Eric coughed and chuckled a little bit. "This is- oh! Oh shit!"

Dani had expressed a similar sentiment when her organ made contact with his. "Oh shit, is that- AAH ahhh, oh God I think this is it!"

Eric nodded, pumping away. At the crest of each pump, he would touch the tip of his penis to her vulva. It felt unreal. But why was he doing it? And why was she writhing?

"Ohh shit, is this a mind control thing?" Eric asked.

"What?" Kat's eyes widened.

"You know, you say phrase and I start pumping the air with my penis and she starts writhing around? Our bodies just seem to be... doing this."

Kat burst out laughing at the misunderstanding. Dani looked puzzled. "What?"

"You two are so close! You're gonna love this when I let you remember sex. Although you're gonna love everything I do, right?"

Eric was working too hard to answer. "Of course," Dani said with a smile.

"I could get used to that," she said. "Oh, Eric, you can stop."

Eric collapsed, sucking in air. He was too overexerted to talk, his face red and shiny. "You guys were so close! Why don't you rest a minute and take it easy. Any guesses as to what sex is?"

"Probably involves our penis and vagina," Eric panted. "And probably that stuff that shot out of Eric," his girlfriend added. "Oooh, this is nice too. Thank you, that feels very good!"

Kat had was applying lube to their prospective genitals. Eric was soaked in sweat and still panting lightly. Dani's eyes were wide with shock, filled with a sort of awe. Her mouth opened and closed once before she spoke.

"Oh, that's... oh, my, that's oh God, there it is that's- that's it! Ahhh..." Dani was crying softly, overwhelmed by the brand-new experience. "Can we- I think..."

She trailed off as she stared at Eric's erect penis. Kat giggled with glee at seeing her friend discover how useful penises could be. Dani surged forward, pinning Eric to the bed by the wrists. Her face inches from his, she growled out an order.

"Put that thing inside of me now."
