Hostel temptation

Last summer, me and my husband went on vacation to a european city. We stayed at a picturesque hostel midtown. One evening we observed a woman from afar. She wore a summer dress that followed the shapes of her body perfectly. We were too far away to see her face, but we admired her posture and elegant way of moving. From afar, we started talking to each other about how we fantasized about her. We moved towards her to get a closer look, which made us want her even more. Even though we realized that she was a few years younger than us. We then went to our room and started having sex, with our fantasy about her in our heads. We even left the door open, hoping that she would come in and join us...
