If there is an underrated body part for pleasure, it is the perineum. The part that connects the asshole to the balls. And I always loved being stimulated there. To recall how the last episode ended, my mistress ordered me to lay on her sofa, feet up, on my back, cock pointing at my own face, and I had a tail butt plug closing my asshole to retain a good amount of milk that had been there for a couple of hours now after driving on the highway, being painted and seeing her work finally concluded.

Surprisingly, I was not even hard. I kept my cool, even though the adrenaline rush was strong, but I got accustomed to being in that position for her. Her knowledge of human anatomy surprised me, since she started to press my perineum in order to stimulate my prostate. She knew what she was doing, and I wondered about her past.

She slowly touched me from the butt plug, playing with its tail and petting it like a cat, until she reached my balls, squeezed them gently and not touching my penis. Clearly she did not want me to cum, as that was her main tool of control. She knew that a sexually aroused man, especially aroused for hours, would make stupid decisions, so she kept massaging my prostate from the outside, playing with my balls as well, and I finally felt what I wanted: to be taken care of.

Besides, she seemed to be studying my body with fresh eyes, now up close. She painted me before, but while touching me she seemed to be interested in my details. I felt some sort of admiration from her, but not worship yet. After complimenting my photos for the first time, very enthusiastically, I wondered to which degree there was a gap between my real self and the subject of my self portraits. The artistic nudes were supposed to create beauty and enhance the positive aspects, and she seemed to be comparing my real body to the art she had seen. Still, she seemed attracted to me, especially my genitals and ass and back, and she seemed to draw an imaginary line along my speedo tan lines.

It seemed like she had something in mind, and I was having some ideas about possible missions, even if I found them uncomfortable, ridiculous and unnecessarily risky. She could body paint me and make me do stuff outside, make me tan with a thong to make me more slutty, or make me go to my laser hair removal session with a butt plug on. I would never cause public distress or put anyone in jeopardy, but I started fearing for my sanity.

All of this came to mind while licking her pussy and through her touch and by glancing once in a while. She was squeezing her thighs but not moaning. Moaning seemed too vulnerable for her, but I was moaning from prostate stimulation. When she sat on my face, I felt the warmth of her skin and the scent of her pussy. We cannot really say she had pubes, but rather a light fuzz that made her look unique and kept her skin looking good and healthy. At the time I did not realize if she had butthole hair because her panties were covering it, but my anal fixation could not avoid trying to figure it out.

Her ass was not meaty, she had had recent health complications so she was quite thin, but I tried to squeeze as much as I could from her butt cheeks, only to be slapped gently. I then tried to use my hands to undress her panties and look at her butthole and she allowed me to do so. I wanted to switch to her butthole but she redirected my head into her pussy once again.

‘Only when you deserve it’ she said.

She was still massaging my perineum and balls while being licked in her clitoris, and she started testing the plug to see if she could remove it or not. Since my ass was up, the milk was stable inside me, but I had no idea what could happen if she removed it. I cared about the mess I could make, but she did not seem to worry about it. Since she was a painter, she had all sorts of protections around the house to avoid painting and staining her furniture, and the sofa was protected as well.

'Now it's your time to make art. An abstract painting.' she said.

I found it extremely funny how she came up with this idea and wanted to laugh, but the prostate stimulation was making me feel really good and slutty.

She put a big canvas in the direction of my butthole, removed the plug and told me to expel every drop of milk I had inside myself. 

As she grabbed the tail and pulled it, I sprayed and squirted the whole canvas with milk, along with anal lube that I used to insert the plug, which was surprising to see, and also some type of natural lube created by my anus. The canvas was put diagonally, and the excess of fluids that did not stick to the canvas ended up on my face.

The canvas was dark, not exactly black, but it was enough to contrast with the white milk, and it was humid to absorb and mix the colors. Without losing any time, she hopped again on my face and this time she started fingering herself really fast. She changed from a cold, focused artist, to an absolutely aggressive sex addict, yelling at me to lick faster because she wanted to cum. I gave it my all, my tongue was tired as fuck, and I was still processing the whole artistic butt milk canvas. Eventually she put herself on all fours on the couch with my head between her legs, the canvas on the floor, and she squirted on my face, and the rest went to the canvas, mixed with the milk. My face had the same fluids. 

'Now it's time for you to cum'

I didn't say a word. Her eyes were still focused in an artistic trance, flowing with ideas, and she started to stroke my cock. I could hear and feel those big, colorful nails. In fitness terms, she stroked my cock through a full range of motion. She said coldly that she loved my pink cock head, which made me feel good and appreciated. She hid my cock head with my foreskin only to watch it retract and reveal my cock head once again. She seemed to be hypnotized by it, that's when I felt that a possibility of worship from her was possible. She was starting to truly love my body. Or at least I got that feeling.

After edging for so many hours, I was ready to explode. She pointed my cock to my mouth and adjusted my head. However, she unmounted me to allow the semen to reach the canvas, and she put it just behind me. My first shot of cum was like a white, viscous bullet. It landed on my lips and hung on my beard. Then I started pumping more and more cum, more liquid, and therefore easier to disperse, so she directed it to the canvas and again back to me. I came with such intensity that in the end I could expel almost solid blocks of cum, accumulated with time that could never see the light of the day. My pipes were cleaned. 

My face wasn't clean, though. On the contrary. I had pussy fluids, milk, anal lube, cum and God knows what on my face and stuck to my beard. She did not want to waste anything, so she wiped me and used the fluids to complete the canvas on a small section dedicated to my face.

'I wanted the cum of creation, the milk of nurture, the pussy liquid. It is a cycle for me.'

After having a butt plug for almost 3 hours inside me, my hole was as loose as can be, it would only wink and not close, but not extremely open and destroyed because the plug was medium size. She took a photo of myself in that position, wasted, with a loose hole, the canvas behind me, and some traces of all the fluids that were still visible, especially on my beard. I was excited to see the whole video she recorded, and now the humiliation recorded, in her own hands, was even bigger and degrading to myself.

'I will still have to process our fluids in order for them to be preserved and to stick well. I know your cum will be easy to maintain at least.'

She was still thinking more about her art than myself. I felt used because she was constantly being professional and felt like her compliments were just a way to keep me in the mood. Still, being used or not, I was getting addicted to her and repulsed by myself at the same time. The post nut clarity was kicking in once again, and I needed to rethink my whole life.

'Since you are not able to talk, I might as well cover your lips.' and she put the butt plug in my mouth, finally clearing my doubts about who would lick it.
