To cut a long story short, for this year's pre-Christmas visit with my girlfriend's family we had a scheduling snafu that put me in an awkward position.

Due to weather and a late change of plan on the part of my girlfriend and her father, I arrived at the cabin we were staying at a whole day and night before they would eventually arrive... and so did my girlfriend's stepmom

As I entered the cabin I was greeted with a semi-naked woman sitting in front of the fire.

"Hello," I said softly.

She screamed and crossed her legs to recover some modesty.

She was naked apart from what appeared to be a sheer body stocking.

I told her who I was and although this calmed her down a little, the color in her face was quite rosy. She composed herself and explained what had happened.

She'd arrived with nothing much more than the clothes on her back - she fell in the snow and removed her clothes to get dry in front of the fire. The body stocking had been packed within a small bag of toiletries she brought with her. She'd decided it would give her a modicum of coverage which was better than none.

I gave her my jacket and she covered herself with it. As we chatted and began to warm up... both in temperature and attraction.

After drinking a glass of wine I could feel myself becoming increasingly focused on the odd glimpse of flesh I was granted as she spoke. As we continued to talk and laugh it was obvious she was purposefully flashing her breasts at me.

She reached out to touch my arm and smiled, "Wow, what a crazy situation we've found ourselves in. Thank you for being such a gent and making me feel comfortable."

"You're so welcome!" I responded with my overeager-to-please attitude.

As the alcohol continued to flow, and the heat increased due to the fresh logs I continued to add, she made a suggestion.

"Now I'm really getting too hot in this jacket, so I'm going to have to take it off, but feel it will only be right if you remove something too," she smiled.

She let the jacket slip off her shoulders to fully reveal the erect nipples I had been given just glimpses of, now protruding from beneath the garment.

As my cock reached its full length, my courage increased in tandem...I stood up, untucked my t-shirt, unbuckled my belt, unbuttoned my fly and removed my jeans. I was about to offer a comment on my obvious state of arousal, but before I could speak, her hand was on the fabric of my underwear.

"I can't believe we're doing this," she said very softly.

She released my throbbing shaft before devouring it with her mouth.

As she took me deep inside her mouth, expertly teasing my cock head with the occasional touch of her tongue, I rolled her nipples between my fingertips. I then made a motion to reposition so I was able to access her now dripping-wet pussy.

With only a light touch of my fingertips I was able to see how ready she was for penetration. Her beautiful and inviting cunt was soaked and open wide. I quickly made my decision and took the empty wine bottle in my hand before slowly inserting it between her labia. She moaned which I took as her approval before further encouragement was provided with an utterance of, "Oh, you naughty boy!"

I worked the bottle into her. Together we picked up the same rhythm. Her moans became increasingly loud. Her body trembled. I positioned her on her front, spat into my palm and used the saliva on her tight asshole. It took a few spits to get the required lubrication to work a couple of fingers inside, but before too long I had loosened her enough to take the tip of my penis. She continued meeting my upward strokes with a strong push that was intent on getting her asshole and cunt full to the hilt.

We fucked hard! She would grab my fingers and put them in her mouth as I pounded her harder and harder from behind. The bottle was almost totally inside so I had to be careful not to let it go all the way. My balls were slapping against the neck of the bottle as she was grinding against me, moaning... almost sobbing. Then she shivered, didn't make a sound for what seemed like a good minute and then let out the loudest "Oh fuck, fuck!!!"

The deep and satisfying orgasm had led to an ultra, unbearable-to-touch sensitivity in the region that currently housed my throbbing cock and wine bottle. She used her shaky hands to guide me away from her sexually charged nerve endings and informed me it was my time to climax.

"Now cum all over my face you naughty, naughty boy!" she exclaimed before once again taking my throbbing cock into her warm mouth.

It didn't take long - she had just started massaging the base of my shaft and balls, while my cock head was inserted deep in her throat when I exploded and quickly pulled out to avoid drowning her in the flood of hot cream she was now receiving on her face and lips.

We were unable to continue our endeavors for the rest of the time at the cabin (for obvious reasons). However, the sex I experienced with my girlfriend was more intense and exciting than ever!

Before leaving, my girlfriend's stepmom did pass me a note which read:

"I hope we get to meet again, I've told my husband about the experience but not obviously who it was with or where it happened. He is so turned on that next time he wants to watch - I hope you like the idea of wearing a mask!"

I'm not sure what to think.
