Finish him.

You catch your breath, stroking him with your off-hand. "..no...I'll finish you with...my mouth..."
"As you wish...get to it." His voice is neither harsh nor kind: it simply demands.
You bob and stroke and slurp with your best efforts. Within ten minutes, Matthias grunts, knocking on the wall a second before hot cum pours into your mouth.
"Ahh...that's good... I hope you understand... since my wife was taken by the imps three years ago, I've needed an easy way to sate my lusts. Can't let myself become lost to the corruption, you know?" Your mouth is full of his pungent seed, which leaks out over your lips and down your chin. "And my patrons? Being able to pay a small pittance to slake their lusts is certainly preferable to the alternative: becoming a corrupted highway predator or demon thrall..." Again, there is no malice, or cruelty, or mockery in his voice. He's a man providing a service and an income, and he sees no moral issue in partaking himself.
"Feel free to stay and work, Alexa. You are free to set your own hours, save that the Hall opens when the Kitty opens, and closes when it closes." You hear him buckling his belt. He opens the lock on the money jar, and fishes out the coins to pass directly to you through the hole. "And remember the bucket."

}As his footsteps recede, you spit the load in your mouth into the bucket. "I remember..."

}You swallow his load, giving a little burp. "No need..." you can't suppress a small smile of satisfaction.{endif
