Make her give you a blowjob

"Let's go to the girl's bathroom down here. It has stalls, we shouldn't have to worry about getting caught there." As I said that I led Kate towards the bathroom. We entered and to our luck it was empty. We quickly went into one of the stalls.
Kate looked at me. "What now?" She seemed very nervous, she most likely never did something like this before.
"Now, you are going to give me a blowjob."
"I haven't done that before. You have to tell me what to do, sorry."
"It's okay." I unbuckled my pants and dropped them to the ground, together with my boxers. My cock was at full attention.
Kate gasped. "Oh wow. I've actually never seen one before. I'm supposed to touch it with my hands first, right?" She moved her hands towards my cock and touched it. That alone made my cock stir and get even harder. Kate grabbed it with both hands and began slowly caressing it, moving her hands up and down.
"That's pretty good", I reassured her. "You can start licking it. Just move your tongue up and down, like you did with your hands, but focus on the top." And that's exactly what she did. She was hesitant at first, but started licking my dick anyways.
Then she did someting I didn't expect: She engulfed the tip of my penis with her lips. As my dick entered her mouth, I let out a small moan. Kate moved further down and that's when I took over. I grabbed her head and pushed her up and down on my cock, basically face fucking her, though not too rough, since she was still new to this. I moaned more and Kate made her tongue go crazy on my dick. This drove me over the edge.
"I'm....gonna cum...." And so I did. I let go of Kate's head and came in her mouth, which surprised her and made her head jump back. My dick left her mouth and my cum flew all over Kate's face and some even landed on her clothing. I quickly grabbed on to her head again and moved her face closer to my cock, so that most of my cum would land on her face.

After finishing and leaving my cum all over Kate, I slumped down onto the toilet seat.
"Wow, that was pretty good for a newbie", I told her.
"I should have swallowed that, right? Sorry about that." She looked at me, seemed sad at first, but then smiled. "That was nice, thank you."
"No need to be sorry. But we should probably get you cleaned up."
We both got out the stall, I put my pants back on and Kate cleaned herself as good as possible. Then we left the bathroom.
