Yes, you're drained.

"Fuck, that was awesome," you said completely truthfully, "you did so much better that time."

"Really? Oh, yay! I have learned so much from you, thank you so much!"

"I... uh... I'm glad I could help."

"Yeah, I think my boyfriend will... wait, what time is it? Everybody is going to be wondering where I am!"

As great as the afternoon had been, you were beat and there was no way you couldn't give any more "lessons" any time soon. "Oh okay... you should go then," and you exchanged contact info with Emma.

Just before she walked out, you quickly added, "I think we may have some more problems to work through. We can figure out a time to meet tomorrow."

"Really, John? You're so sweet to take so much time from your vacation for me!"

Your selflessness truly knows no bounds.

After Emma left, you realized you hadn't actually had lunch and the whole afternoon had slipped past. You decided dinner was the next thing to deal with. The combination of blowjobs and pushing suggestions into Emma's head all afternoon left you exhausted. You could barely handle complex concepts like a restaurant menu, but you managed to get some food.

On the walk back to the hotel, you texted Emma, "You made a lot of progress today. I'm very proud of you."

A few minutes later, the reply, "☺️ there's so much i wouldn't have know without u!"

"There's more we should talk about. I think we should meet at 11 tomorrow." Wait, you didn't feel any...

"I'm busy in the morning. 1?"

Shit... commands don't work by text message. Good thing you planted the idea of meeting before she left. "Sure, come to my hotel when you can."
