My first: Rough Sex

Back when I was 22 (or so), I met a girlfriend "Holly" that I was totally infatuated with. She initiated contact with me after a party and after only a few days started an insanely red hot sexual relationship that would last for a short time.

Several months into the affair, we met at a friends place*, where we all had a great time playing board games and such.
Then said she was going to bed and told us we can leave at anytime.
We snuggled and kissed for a bit and she (as usual) started to do little things that made it clear** that she wanted sex, and the heat was turned up a bit.
Things took a strange twist when she started to resist my undoing her top, so I backed off and continued our hot make out session. Since I loved kissing her, we simply carried on.
A few minutes later, she once again resisted and squirmed out of my embrace.
Concerned***, I asked if she was okay as her demeanor changed.
This cooled things down quite a bit and I left.
Several days later, she told me that she wanted me to take charge and "make her" do things.
This was a bit of a foreign concept for me at the time.
A few days later, we were at it again.
Smooching.
Rubbing.
Oh, Yeah! I love a good smooching session.
It was during this time she looked me in the eye and pushed me away.
I blinked.
Having paused for a moment, I simply went back to smooching her again.
This time, accompanied by a slap to the face and a punch to the chest.

Did I mention she worked out? She knocked the crap outta me!

The conversation we had a few days ago finally went from some theoretical discussion to fact.

Getting closer to her, she was actually putting up a substantial struggle highlighted with a slaps and a few well placed punches.
It was almost approaching a fight, but there was kissing involved.
This was the most surreal moment of my young life.
Bits of her clothing were being torn off until she was nude, complete with marks and bruises.****
As I began pawing at her breasts to suck on them (she had AWESOME nipples...kinda like PTA Mom!), she'd mash my face in them and told me to bite them hard, then pulled me by the hair, slapped me, and then dared me to take it.

WOW!

"You're not enough of a man to take me, are you!?"

THAT set me off and we started to trash my friend's apartment with an ongoing fight that went from one end of the house, to another.
Throughout the episode, I forced my cock in her pussy, where she would surrender for a moment, before she'd kick me off and the fight would resume.
Every time she did this, it would just piss me off even more!

I finally got the remnants of her slacks, and tied her arms together and gagged her.
Believe me, it wasn't easy.

Having bent her over the coffee table I tied her feet to the legs of the table with my shirt (now in several pieces).
STILL struggling, I had to hold her down as I went behind her and pushed my cock in her pussy.
Catching a glimpse of movement behind me, I spotted our friend peeking through the crack in the bedroom door with a big smile on her face. I moved to the side to allow her to see Holly's pussy.
She motioned me to slap it.
Giving it a light hit, I got a reaction from both Holly and my friend.
She motioned that I needed to hit her even harder, and on the clit.
I followed her instructions and after a couple of swats she started having an orgasm. I wanted my orgasm so I continued to fuck her roughly until I came into her. Was about to untie Holly when my friend came out, and motioned to her. I dipped my fingers in Holly's pussy with her juices and my cum intermingled and fed it to our friend's mouth.
She seemed giddy as she ran back into the bedroom.
I just shrugged and untied her.
We were a sight.
Both were bruised, a bit bloody, and we both had scratches.
Our clothing was strewn about the condo and with the exception of my Jeans, they were all torn to shreds.
We walked out of the place an hour later.
I was shirtless with missing a sock,***** SHE only had a towel on.
The few neighbor's that were out that time, just assumed we were going to the pool.
She thanked me for giving her what she wanted.
I asked her if we could tone it down a bit next time, but that it was fun.
She tossed me her towel as she got in to her car and drove off.

All I could do was stand there in stunned silence. This girl constantly amazed me and would show me a few other things as well.


*We were both still living at home at the time and my friend was kind enough to let us use her place. Later on my my/our friend loved hearing us...and more so.
** I wasn't that bright when it came to hints.
*** Never experienced this before, I was thinking of "No means No" and backed off.
****It was at this point that I discovered she was also into S&M, something that I was just getting into at the time.
*****The sock was found a few years later as she moved out.
