While moving up and down, Nokko tries lowering her head as far as she can, taking it into her throat, then raising her head up to the glans while tightening her lips to prevent drool from dripping.
During this, her soft tongue flicks around. Ah, it feels good.
"Amazing, Nokko, you might be a genius."
The girl shakes her head as if to say "not at all" and starts to pick up the pace.
"Ah- good, good, but that's enough."
Nokko looks at me with eyes that seem to ask "why?" She looks a bit sad.
"It's good, but if you do more than that, the semen will come out."
The girl who had been holding the penis in her mouth swallows the saliva that had accumulated and opens her mouth.
"Why isn't it okay for the semen to come out?"
Well, that's a good question.
"The premise is that customers come here to put their penis in a pussy and ejaculate. In places like this, it's a certain amount per ejaculation, so if you make it come out in your mouth, it ends before putting it in the pussy."
"But I was told to make it come out in my mouth and get a tip."
The black-haired girl looks unconvinced.
"Well, that's true, but once it comes out, it takes time for the penis to get hard again, so if you make it come out in your mouth, most people will just end it there."
"So what should I do?"
"My recommendation is..."
Here I am, lecturing about the sex industry in front of a naked young girl.
"First, start with fellatio while being sexy and flirty, and when it gets hard, insert it. But it won't go in if Nokko isn't wet, so somehow get them to lick your pussy. Insert it and ejaculate, then do a cleanup fellatio. Usually it ends there, but if you keep licking and it starts getting hard again, ask if they want to finish in your mouth. Most people will probably pay a tip and ask for it."
I speak rapidly, sounding a bit nerdy. The naked Nokko asks a question, looking puzzled.
"Why can't we do it in the reverse order?"
"That's a good question," I nod, also naked.
"Nokko, you're small so your pussy is tight and probably can't take it a second time. But your mouth can adapt flexibly, and you can naturally aim for a second round following the cleanup fellatio."
The naked young girl nods repeatedly.
"The customer's payment only increases from three or four silver coins, which honestly isn't much of a concern, but Nokko's share doubles from one silver coin to two, so actively aiming for a second round in the mouth is the right move here. Your interests align with the customer's."
After I finish speaking in one breath, Nokko asks a question.
"Shouldn't we aim for a third time?"
"Well, it depends on the case, but men have something called a refractory period, so it probably won't get hard for a while after ejaculation and time will run out. If time runs out in the middle, it leaves a feeling of incompleteness. You need to send them home feeling satisfied for them to become repeat customers."
"I see."
Nokko nodded as if she understood. While naked.
"By the way, this is advanced, but if you have a long time and the setup is to ejaculate multiple times from the start, it's also possible to finish in the mouth first and take it slow for the second round. But Nokko, you're basically doing short sessions, so I think it's better to aim for one silver coin tip at a time."
"I understand."
Nokko suddenly took my now shrunken penis into her mouth.
"I'll twy it."
