[MF] Co-worker's friend humbled me

It was a typical Friday happy hour with some co-workers, and one of the girls had a friend, Kara, visiting from out of town. She was so petite, about 5'0", A-cups, and had the cutest dimples. If I did see her get ID'ed at the bar, I wouldn't have believe she was 24.

She showed up with a dufflebag, and I asked how long she was staying. "Just two nights, but I have everything I need."

I made a joke about how I thought women travelled with extra outfits. She said she had comfy clothes for the next day, going out clothes, a travel outfit for Sunday, and her vibrator.

I nearly spit out my drink and she commented "Sometimes a girl needs some help."

Later on in the night we got friendly, and I asked her about the vibrator. Things like size, preferred speed, clit tickler, etc. She said it was just the basic, but said "The problem is that no guy lasts long enough to get me off, so I always have Buddy with me."

My curious face gave away my thoughs. "I'm so tight that guys almost nut instantly."

Fast forward a few hours later and Kara is back at my apartment, where she proceeds to look even younger naked than she did at the bar. I don't want to totally describe what it looked like, but she was completely smooth, petite, tiny tits, and hot as fuck.

She proceeds to have me go down on her, which was great. I tried to transition to sex a few times, but she kept telling me I wasn't done yet. When I finally got her to cum, she had me lay on my back. She straddled me and just rubbed her pussy up and down by cock while we made out. Finally, she got a condom and her vibrator. I tried to tell her she wouldn't need it, and she just told me to shush.

With expertise, she got the condom on me and then slowly lowered herself on to me. She was extremely tight, and it felt good. Then she held the vibrator to her clit, turned it on, and just said "Watch this."

To this day, I don't know how she did it, but she didn't bounce. Just a slow grind back and forth, but the way her pussy squeezed my cock like it felt it was going in waves was insane. Plus the little bit of vibration I felt had me fighting for dear life.

If I lasted 15 seconds, I would be proud. I nutted so hard, but she wouldn't stop. I was in that blissful agony of overstimulation, and then she came again, which had her gripping me to the point of discomfort. She rolled off, I went went limp, and she just said "Told you."

We tried again that night, and it was the same result.
