Let's get educational.

"Actually," Kat said before Dani could answer, "I think I want to show you both the ropes."

"You want me to forget about sex?" Dani asked. Kat nodded and she did a double take, then looked down at Eric's boner. "Whoa, what the hell is that? Do they all do that?"

"I have no idea," Eric said anxiously. "It's never done this before. I- you were letting me touch your breasts a second ago and it made it harder."

"My breasts?" Dani asked with surprise. "What about them? Why did you want to touch them?"

"Maybe try again," Kat suggested.

The couple shrugged and Eric brought his hands to Dani's chest. As his hands covered her supple flesh, a blush came to her cheeks. "Oh, wow," she said in a strange voice. "What's that feeling?"

"Is she having sex too?" Eric asked Kat, who giggled.

"Not yet," Kat replied. "I want to see if you can figure it out."

Dani put her hands over Eric's. "I think it has something to do with my tits," she exhaled.

"They certainly feel amazing. But what about this thing?" Eric gestured to his penis and Dani looked it over. "It seems related to your breasts. But why would they make my penis harden?"

Her eyes were still fixed on his member. "I don't know, but it's kind of appealing."

"My dick?" Eric said with mild disgust. "I piss out of that. How is it appealing?"

"It just is," Dani told him. She took her left hand off of his and reached out. "Can I touch it?"

"Sure, I gue-Whoa, Dani, that's- Ah!"

Dani was tapping along the side of it with her fingernails. As she lightly ran her index fingernail along his urethra, Eric cried out. She looked up with concern.

"Everything ok?" They made eye contact and Dani saw something completely unfamiliar spark in his eyes. It was like he was starving and she was a hamburger.

"Don't stop."
