the fling, part 2

I know, there wasn't a part 1, but I'm just arbitrarily calling the previous story 'the fling'

Anyway, we hung out a few more times, and each time she'd make her way up to my area, she'd try her hardest to make me buy her clothes and food, then we would end up at my place watching a movie where one thing would lead to another, blah blah. After our third time sleeping together I found myself losing interest, given that we had basically nothing in common, aside from our complementary plumbing.

I felt as though I was at an impasse given that the present situation wasn't very interesting to me. So I decided that I was going to either A) do something to potentially improve the 'relationship' or B) end it completely.

The next time we were hanging out, I asked if she would be interested in doing something kinky. She seemed almost excited at the prospect of doing something sexually deviant, which was something of an unexpected response. When we got to the portion of the evening where were heading to my bed, I started explaining that I'd like for her to wear some latex garments. I pointed at a pile of black rubber and she started sorting through it.
She selected a libidex-made dress and stockings. I easily helped her into the outfit, easily since she's quite fit.

I was hoping that sharing my fetish with her would somehow spark some bonding and closeness with her that I was otherwise not achieving. Of course, once she was dressed I was basically incapable of keeping my hands to myself, but once things got sexual, it began going down the same path of feeling disconnected and odd about the encounter.

Part of the way through she started barking orders to me: harder! harder! I was taken aback, since I had never had such a demanding partner. I tried to do as she said, but as I did she demanded, "pull my hair!"
I stopped momentarily and thought; sex and aggression are two things that don't go together at all! for me at least. However, I was subjecting her to some of my fetishes, it would be unfair for me not to entertain hers.
"What's up?" she asked, given the abeyance in action.
"Do you mind if I go put a dildo on?" I figured I would up the ante a bit before trying to satisfy her demand. However, given my strange question, I was expecting to give a further explanation. So with my lips pursed, ready to inform her of what I was planning on doing-
"Sure!" she abruptly responded.

I was a little surprised, but I figured I wouldn't go against a good thing.

I went into the bathroom and tucked myself between my legs as I slid the harness in place. Once I situated the base of the prosthetic to the base of my member I pulled a pair of moulded rubber briefs over top the harness.

I made my way back to the bed with the tip of my newly enlarged member bouncing with each step to her motionless body laying there sprawled out in a pile of trussed hair and shining latex.
Already belly down, I pinned her chest down to the sheets and slid in. She purred at the increased size as I tried my hardest to be as violent as possible, but it was difficult for me to muster the energy to satisfy.

"Pull my hair!"
My hand leapt up without a conscious thought going through my mind. My fingers made divisions of hair in her scalp as it drew up the back of her head.
"Now pull!"
I made a fist and lightly pulled.
"Harder!"
I applied a little more force.
"Harder!"
Out of frustration I tugged violently, followed by an immediate feeling of remorse. Her faced quickly jerk up, "Good!"

This continued on for a few more minutes and I slowly brought it to an end. I again felt disconnected from her and even more strange about the situation as a whole.

After that point she went abroad to visit her mother for a month. I felt like this would be a good opportunity for me to remove myself from the situation and cut contact. However, unexpectedly, even while away she continued contacting me...

To be continued...
again..
