Why would she?

Dani continued to gently stroke Eric's member and tried not to laugh at the faces he was making. She turned to Kat with confusion.

"Is this sex? Why's Eric acting like this?"

Kat shook her head with a smirk. "You're getting warmer, but I wouldn't call it sex yet. You have one piece of the puzzle."

They were interrupted as Eric let out a sickly groan and a strange-smelling goop shop out of his penis. Dani jumped back, but it splashed her face and shirt. Eric collapsed back onto the bed, panting and sweaty. "Oh my GOD, babe," he said. "Is that sex? How have we not done that before? That was unreal!"

Dani had scraped some of the fluid off of her forehead and was looking at it with concern. "Uh, Eric, something... uh, this stuff came out of you. Fast."

"Fast?" he said, his voice edged with a note of anxiety.

"Yeah, it shot out. It got all over me. Kat, is this ok?"

"Don't worry, Eric's safe," Kat reassured them.

"Thank God," Dani said. "I was worried if he died or was seriously hurt we wouldn't be able to keep playing this game."

"Fuck," Eric said. "I didn't even think about that. I was just worried I left a stain somewhere in her room."

"Alright, back to the task at hand. Kat said that what happened was safe, right? But since neither of us has ever heard of that happening, it must be related to this missing concept. She said that we figured out one piece of the puzzle-"

"She did?" Eric asked, still catching his breath.

"Yeah, you were distracted," Dani smirked. "Or you were just moaning so loud you didn't hear her. I think that this thing with your penis was part of sex. Since it's apparently something we do together, maybe other puzzle pieces involve my body?"

"Your boobs?" he suggested. "Touching them seemed to have an effect on you."

Dani blushed again as she recalled the feeling. "It sure did. But I don't know how your penis relates to my breasts."

Eric sat up. He was still naked on the bed, and they both noticed that he had gone soft again. "Uh-oh. It shrank again. It hurts just a little bit, but still feels kinda good. Here, can you touch it again?"

"Ok, but if it starts erupting again I'm out of here," she joked as she reached out. When she touched it, there was a tiny twitch, but it didn't stiffen. "It, uh, is still responding kinda..."

"It feels like the hardness is coming back slowly. But we still don't know how it works with your tits. Maybe we try touching it to them?"

Dani shrugged. "Couldn't hurt. Here, you climb on top- there we go- now just lay it right between them, I guess. How does that feel?"

"Great! And I think it's coming back to life now. How does this feel for you?"

"Ok," she said. She grunted and fidgeted. "You're heavy. This doesn't seem like the right way to do it. Should we try something else?"
