My parents are pretty well-off, Dad owns a successful business, an electrical supply company and Mom owns an antique and decorator shop. Me, I'm their only child and I'm in college, I'll start my sophomore year next year and I'm majoring in business and finance and plan to join Dad's business when I graduate.

I work summers for Dad, except for the two weeks that I take as a real vacation. This year, I'm taking it at home, after all I have a large pool to enjoy which is great.

I'm also house-sitting for Mom and Dad as they're away on a Mediterranean cruise for two weeks to celebrate their twenty-fifth anniversary.

During my two weeks, I also have a house guest, Christina, who has been my lover for the last two years.

We met at my Mother's birthday party two years ago. We were introduced after she had come in and about halfway through the party, I was outside with a beer (yes, I was only seventeen but I was responsible and my parents were right there and the bartender was under orders as well) and Christina came out with her glass of chardonnay and we talked about my plans for college and such.

She had long blond hair and was beautifully-dressed in a black sheath that cut across her breasts giving me a nice view of her cleavage. She was trim with a nice figure, she just turned me on. It was as simple as that.

I'll never forget when she asked me, "Noah, do you have a girlfriend, is she here tonight?"

And I said, "No, not really, I think I've been waiting for you."

Yes, that's pretty direct for a seventeen-year old but you haven't seen Christina.

She laughed and said, "Well, my dear boy, you need a much younger woman, I'm far too old for you," then leaned forward and kissed me softly on the lips.

I looked at her and said, "Well, my mind is made up, now how do I convince you?"

"Well, it's hardly the place for that, Noah, in the middle of your Mother's birthday party."

"My room is just upstairs," I offered, looking into her eyes.

"You are charming me out of my good senses, Noah. I hope you know what you're getting into."

"No, but I do want to find out."

"Well, perhaps you should show me your bedroom, then," and I led her by the hand up the back stairs to my room.

As soon as we were inside, I closed the door and Christina's arms came around me in an embrace as we kissed, really kissed, for the first time.

Her tongue was like she was fucking me with it as her hands roamed my body up and down. She pulled away, turned and said, "The zipper's in the back, Noah," and I knew then that I was entering a new phase of my life ... me, at seventeen, becoming a woman's lover.

I slid the zipper down and she was out of her dress and standing there naked except for her heels and knee-high stockings. She wore no panties and no bra.

She was beautiful, long legs, small, firm breasts, dark red nipples, flat stomach, smooth, shaven pussy. I have never been so hard.

"I hope you're not disappointed, Noah," she said softly as I quickly disrobed. She sat on my bed and took my cock in her hand, leaned toward me and, as I watched, slipped her lips over my cock and began to suck the tip as her tongue ran all around the crown.

"Oh, that's so good, you're better than any girl I've ever dated, mmm," and she sucked me for a minute more, stood up, told me there would be more of that another time and had me lay down on my bed.

She then squatted up over me and lowered herself down as she held my cock, pushing herself down on me until she was sitting on my pelvis.

"Mmm, not what I expected at Grace's party but it's a lovely surprise present from her handsome son," she said as she began rocking back and forth as I arched my hips up savoring the wonderful grip her pussy was pulling me with.

"Oh, I can't believe this, it's so wonderful and you're so beautiful," I groaned as I rubbed her breasts up and down.

"I'm not too old for you?" she asked.

"Oh, Christina, I think you're perfect. You're just beautiful and, oh, so sexy. So much more sexy that the girls I know. And, this is just the best. So sexy."

"Mmm, well, to be honest, I'm loving your nice, hard cock. It just feels wonderful," she said as she ground down on me and twisted her hips back and forth.

"How old are you, Noah? It occurs to me that you could be underage and I'd be an awfully naughty woman."

"I'm seventeen and in this state old enough for a while now. Don't worry, anyway, I'm loving this and I want us to be together more if that's okay with you. Maybe I'm too young for you?"

She was drawing all the way up off me, all the way so my cock came out of her, then carefully, slowly pressing me back up through her pussy lips and deep into her each time. All the way out, all the way in. It felt sensational.

"No, not too young, not with this nice, hard cock of yours. Just what do you think my age is, Noah?"

I was only seventeen but I knew a woman's age was dangerous ground to tread upon so I kept it vague.

"Um, probably like thirty?"

She smiled, leaned over, kissed me, then whispered, "Noah, you know how to make a forty-five year old woman happy. Thank you."

Then she rose up, just leaving the tip end of me inside her as she moved her hips around in a circle, just massaging the crown of my cock with the inside of her lips around and around. I just couldn't hold off any longer.

"Oh, I'm cumming ... uh, UH, UH, UNH, mmm, mmm," I moaned and as soon as I started cumming, she pushed down all the way then fucked me fast, really fast as I had the most phenomenal orgasm of my life.

She was really moving fast, then began to moan, "Ummm, mmm, mmm, oh, oh, uh, UH, UNH, UNH, mmm, mmm."

Christina leaned over and kissed me, her tongue caressing my mouth as she continued to move her hips up and down. Then she raised up and whispered, "God, Noah, you're still hard as a rock. I think I want to fuck you again," and she did.

We finally got dressed and snuck down to the party which as, thankfully, still going on.

She told me she was calling it a night, after all it had been far more exciting than she had expected. I walked her out to her car and we kissed more.

"I want to be your lover, Christina. I hope you say, yes."

She opened her car door, reached under the seat and put a small metal object in my hand. I felt it and it was a door key.

"Two-seventy Grand Avenue, Apartment 18C. Can you come for lunch tomorrow? I can't promise what I have in the fridge but you won't leave horny, that's for sure."

I made a date for lunch and I ended up spending the night, with Christina, leaving the next morning the most sexually-satisfied I've ever been. And, I left not only with the key she'd given me but with her cell number and email address.

That was two years ago. We've fucked hundreds of times, Christina just never says stop and, well, I'm nineteen now and she keeps me well drained of semen.
