'Mysterious Trunk', colour 'Champaigne in the dark'

It was a pair of black pantyhose with a hole to let out my entire ”package”. Added to this was a champaigne knee high, that I'd stiched around the hole and cut off the top from so it formed a very visible sheer and light hose hanging out through the hole.
Now I put this on, struggling a bit to get my now erect dick into the hose, followed by the balls. The sensations just made me harder and bigger.
As I looked up briefly I noticed PG leaning a bit forward, intensly studying my work, but I wasn't quite finished yet.
I put on a ”sweater” identical to her's, but black to match the lower part.

Now I was ready, and moved to the side so she could see all of me.
It was clear that PG was being turned on by these events. Her hands had gone from covering the vitals to rubbing them gently. The legs were spread wider apart and her eyes were locked at my crotch.

I grabbed my nylon clad stiffy and started to move my hand up and down the shaft while looking at PG. Her immediate response was to intensify the rubbing of her own nyloned crotch.

• ”Do you like it?” I asked.
• ”Oh yes, lovely!” she said, without letting her eyes off my cock.
  I couldn't tell wether she referred to my clothing in general or only to the detail she was studying, but I decided to stay in character and present the garment in more detail. So I began to turn around, to let her see me from all sides, while commenting; - ”This model is called 'Mysterious Trunk' and is available in a wide range of colour combinations. This particular variant is called 'Champaigne in the dark'. Mysterious Trunk is made out of crepe nylon, which provide a perfect fit for most body shapes and sizes. It's very versatile and can be used in many ways and situations.”
  I was now facing her again, and started to move slowly towards her.
• ”Do you wan't me to demonstrate some of the available usages?” I asked.
  She nodded her head in concent.
• ”As you can see...” I continued ”... the penis is normally hidden within the nylon, only vaguely visible. The 'Champaigne in the dark' colour combination seem to draw attention to this area anyway though...
  The total freedom of movement makes it very comfortable, and 'spanking the monkey' is a no brainer.”
  I was now standing right in front of her, my hands to the sides and my cock pointing straight out in her general direction.
• ”Feel free to test rubbing my dick while wearing nylons. It's a bit different than doing it with bare skin.”
  At first a bit hesistant, she then slowly and gently touched me with her left hand. It felt almost electric, and my member twitched and jerked in reaction.
  Now she really grabbed it and began moving her hand up and down the shaft. She was a bit too rough, but it felt great all the same. I used this moment to watch her tits. Firm and perky they strained against the tense nylon encasing them. The nipples were dark and hard, clearly visible.
• ”Does this feel as good for you as it does for me?” PG asked, looking into my eyes.

• ”If not then you must have a really good time!” I replied. ”But please let me continue with the demonstration now.”
  She reluctantly let go of her grip.

• ”I can also fold or roll the cover back, to expose some or all of it's content” I said, while pulling and folding the nylon back until it framed the outline of my scrotum and cock base. The cock head was now merely inches in front of her mouth...
• ”This way the meat bone is available for any activity desired, like for example a blow job,” I explained.
  She was immediately in on it, asking - ”Can I try that?”
• ”By all means, please have a go at it.”
  She leaned forward with her mouth wide open. This time she used her right hand to hold the dick while steering it into her mouth. She licked a bit on the forehead while fondling my balls with her hand, both activities sending shivers through my spine and made my pole grow even bigger.
  Then she plunged forward, taking the whole length in her mouth and down her throat. Nobody had ever done that to me before, and it felt great! Clearly this wasn't the first time she was giving head, as her tounge pressed against my shaft while she added some serious suction to her work.
  As she slowly began to move her head back and forth on my dick her eyes met mine, expressing lust and desire. This made me hornier than I'd ever been before, and I had to figure out something to do not to shoot my load instantly.
• ”So... do you approve with this 'Mysterious Trunk' design?” I asked.
• ”Nnnngggg!” She anwered, slightly nodding her head in approval as she grabbed my hips.
  Now she steadily increased the pace, slamming my groin hard into her face as her head bobbed forward and then pulling back until only the tip of my cock was between her lips before she went down on it again. All the time she was gazing into my eyes.
  That didn't cool me down one bit, so I told her straight;
• ”If you don't stop that right now I'm going to cum in your mouth!”
  She let out a short giggle and then just increased her effort.
• ”Well, I warned you...” I said, now unable to hold back any longer.
  My meat cannon started to spew it's sauce in an eruption like I didn't think was possible after my recent masturbation.
  PG held the cock head in her mouth, feverishly sucking and licking on it, as if it was a drinking straw, until she couldn't get anything more out of it. Then she swallowed the load and gave me a grim smile...
• ”I like your product demonstration, but... a slight problem have emerged. I think you'll either have to do something about it or fail in your intention.”
