Polish the rod

Her pussy was aching for release, but as horny as she was Me still realized that she couldn't just start recklessy humping that dick.
Servicing him would give this bath a whole different meaning, but losing to temptation and get off with his rod also wasn't good... having another man's penis around her pussy was never a good idea.
But she was still too horny to reason out why she shouldn't just accept his claim and obediently wash his cock back in thanks for his effort in cleaning her out, so...

The best solution she came up with, wasn't really a solution as she indeed began to slide her pussy back and forth over his shaft, using her love juices to scrub his meat and gasping in pleasure as she felt the irregular texture stimulate her slit in ways she didn't know possible.
Old Mo's erected pole wasn't just engorged unnaturally, there were various small bumps along the way and some veins could be seen and especially felt very clearly... rolling her hips over it would mean her already very sensitive pussy would feel it all, the hardness, the heat, the bumps, the over-pumping blood... it was especially so for her clit, overabused from all the rough trips back and forth over the bumpy hills of that dick terrain!

She kept seeing stars and even triggered a few mini-orgasms that only fed her hunger for more, but despite so she didn't dare go faster.
As good as the quack doctor was in getting females horny, Mei's cultivation was ultimately established upon sexual practicies.
She might not specialize in those sort of techniques, but with such a fundation and her own main cultivation technique being the Loving Heart Virgin Mind Mantra that gave the biggest returns for those who kept themselves to a single partner... she had the mental facuties to keep some rationale even while very horny, or at least it was so when there wasn't any aphrodisiac and **** or special techniques involved.

Arousal by acupoint wasn't a technique special enough, and he couldn't use any aphrodisiacal incense unlike when he "treated" her in his room... all her arousal was pretty much natural, which meant she could still find it in herself to not give in to temptation and go crazy over that dick.

Old Mo noticed how the girl wasn't humping his dick with the relentless abbandon he expected and frowned.
If she kept going like that, there was little he could use to push her limits later on. He was already playing with her tits and trying to manage her pleasure as to not make her cum, only trying to have her seek more, but since she wasn't falling for it he attempted to set up a trap "That's some nice work you're doing down here, but you gotta polish the head too"

The head?
She didn't immediately understand, or at least not till she looked down to see the purplish over-swollen bellclapper-like tip of a dick popping out the water right between her legs.
She... had to polish that too? It was obviously meant to use her pussy to do so, having to lenghten the swing of her hips to cover the whole 12 inches of male meat right up to its head, and it was no easy feat.
But he prompted, and she didn't find it in herself to refuse... but how was she going to do it?

He was quite big after all and the bath was not only a bit cramped but also quite slippery...
