"Polish my staff" (M/M)

"Well lad, I see you don't have much that is of value to me. But there is one form of payment I think you are capable of offering." he states. "What's that?" You ask, not catching the subtext in his voice. "Let me show you." Says the old wizard, before removing his robe and letting it fall to a pile on the ground. Now, standing before you nearly nude, he fishes a large uncut cock out of his blue & star patterned boxers. "My offer is for a cute little twink like you to suck this, that is IF you do want to grow that pathetic dicklet of yours". After a moment of hesitation, you know you'd do damn near anything to end the torment and loneliness of having a below average member. "Fine." You say, knowing this wizard has you over a barrel.

"What?" Says the old magic man "Huh?" you ask. "say it like you mean it you little whore".

...

"Can I please suck your big cock in exchange for a potion of greater manhood?"

"okay lad, sign here." He says as a quill pen and scroll appear in front of you, which you sign.
