Yes, she is

"Good," you answer. Even though the massage is erotic, you're still in control of yourself. "So, after massage, what else you can do?"

" Have sex?"

"Yes, but you can also do something else, " you say as an idea comes to mind.

"What do you mean, My Lord?"

You look at your erect dick, begging for a release. "Slowly masturbate me until I climax or if you're willing to, suck it,"

Gretha looks at you and then at your dick. Then she slowly takes your dick into your mouth until the whole length. Slowly, she sucks your dick until you cum inside her mouth. Gretha gags but quickly control her mouth so swallow your full cum.

"Tell your customer up front, you'll charge 1 gorschen for a massage, 2 grorschen for massage and masturbation. 3 if they want a blow job. If they want to suck you until you cum, after you suck them, it's 4 grorschen."

"They pay to pleasure me?"

"Yes. Remember, experience. Maybe 2 grorschen if they're only here to suck on you."

"But then I will get fewer."

"True, but how often you have sex each time, compared to how often you can get men off by masturbating them? Besides, not all has to do with sex. For example, if this becomes a tavern, you can persuade people to drink a lot of mead and get paid by how many you sell. For example, if your customer buy certain amount of drinks, you can give him a free service."

"You're right, My Lord,"

"There's a lot of things you can do besides having sex. Unless you really like sex."
