my [18f] gf’s first threesome [ff] [group]

I met my girlfriend in the first month of college, around last September, we can call her Alex. She’s 18, 5’8, 125 lbs, skinny, Asian. I’m 5’4 with blue eyes, a curvy but petite body, pale, with pink hair.

Her friend, we can call her Lilly, from Alex’s old highschool came to visit for a night, at that point Alex and I were just hooking up often, not dating. We drank with Lilly and hung out with friends, and I remember finding Lilly very attractive. She was short, with pink hair and adorable freckles. Lilly and my girlfriend had sexual tension in highschool but never did anything. We both flirted with her. After drinking some more we were both clearly all over her, and being a bit of a brat, I may have given Lilly more attention than Alex in an attempt to stir her up. It worked, of course, Alex is quite dominant in our relationship and prefers me to be completely her’s.

The following weekend Alex and I decided last minute to go to Lilly’s apartment. Our college dorms are small and we both have roommates, but Lilly had her own apartment with a queen bed, small kitchen, and bathroom. We spent a bit putting on cute outfits before going out and brought a rack of beer, our strap-on, and a spiked D ring collar.
