This story takes place about six months into my relationship with Jenny. For background, I was 18 and had just graduated high school, she was 20 and had just finished her second year of college. She had also just moved into a new apartment with a new roommate, her friend Dawn.
Jenny warned me prior to the move that Dawn was also bisexual, so Jenny's exploration was likely to take a leap forward. I reiterated to her that she was welcome to play with any other women she wanted, so long as she occasionally told me juicy stories. I explained to the both of them at the time, as a man, I was able to provide Jenny with certain things, and if she wanted those things it was my preference that she obtain them from me. But for those other wants for which I lacked the necessary equipment, she was free to explore. I think both she and Dawn were surprised by my lack of jealousy, but definitely took advantage of it.
As did I. Many of my date nights with Jenny ended up at the apartment with the three of us playing together, which inspired many stories. But this story is about one specific encounter.
I had spent the night at their apartment, an unusual occurrence as I was still living with my parents for the summer before moving away to college. It was just Jenny and I for the night, as Dawn worked late. But we had fun, and ended up with a good night's sleep naked in her bed. The next morning, Jenny needed to leave for work early, but invited me to stay and sleep in, which I did.
