After I finished cumming and was laying there breathing heavily with my cum all over the place, she was still sitting there not saying much with her hand over her mouth. Then she just burst out laughing. The conversation went something like this (paraphrased, because I don't exactly remember it, but I remember the gist. I put a * next to lines I'm 100% sure that's how they were said):

*Her: "Was that an orgasm?"

*Me: "Yes, that was definitely an orgasm."

Her: (laughing again) "I learned about it, but I never knew it was so messy. I thought it just kind of dripped out."

Me: "Well, normally you should hold the penis so it all goes in one place. Also the orgasm feels better if you keep stroking while it's happening."

*Her: "Oh...." (looking kind of sad) "It didn't feel good?"

Me: "No, no, it felt good, just... Maybe next time you can try to hold it and keep stroking instead of letting go."

Her: "Next time, huh? Are you sure there's going to be a next time?"

Me: "I think there will be. So, uh... Can you give me some tissues or something? I need to clean up."

She went to the bathroom and came back, and by that time my penis was pretty much flacid. She helped wipe me down on my chest and stomach and cleaned up some spots on my bed. Then:

*Her: "So that's what your penis normally looks like?"

*Me: "Yeah, pretty much."

*Her: (giggling) "It's a lot smaller."

*Me: "Yeah, guess so."

(I was actually kind of hurt by her saying that, but didn't take it too personally.)

We finished cleaning me up then just hung out for a bit in bed just talking and holding each other. After an hour things got hot and heavy again and she was eager to try her second handjob. She did much better the second time. I also gave her an orgasm by rubbing her clit and fingering her while sucking on her nipples. We didn't get to oral until several sessions later, but that's a whole other story.
