As our intentions were clear, (what do you expect from an acquaintance found on ISS?!!!) I wasted no time in feeling her thighs…they were heavenly!I...slid my hand along her sexy shoulders into her stringy top, and was overjoyed to find the absence of a troublesome bra!! “Why do you think I went to the restroom?” I was overjoyed…and then slipped in my hand into her skirt…to find no panty!! She opened her legs to allow my fingers to probe her. I inserted my middle finger into her pussy as she. She then said, "I'll be right back." She left the room. Several minutes later, when she returned, she was wearing a tight, short skirt, white nurses uniform, with cap and black fishnet stockings. Her legs were great and she had very large breasts and a nice plump ass. She came over with two pair of handcuffs and cuffs my wrists to the head frame of their bed. I had a raging hard-on. She said, "Let's take your temperature, shall we?" She then placed a thermometer under my tongue. As she did. Lena started to pull back and she moaned out loudly.“Slow and easy, although this isn’t my first time, I’m still swollen tender just like you,” Rebecca said to Lena.Finally, with a bit of pressure and a little wiggling, she slipped her fist out of Rebecca. She just stopped and looked open-mouthed at how gaped open her pussy was. She knew the other night she felt really open but had no idea that she may have been that open. Today she didn’t feel it as much probably because she had started moving. She held her hand out to me and I took it. She pulled me and I stood and moved closer to her. ‘Come and join us.’ She stood and led me, compliant as I was, to a group of her friends, she introduced me although I had no idea how she knew my name. They were fun and friendly and, like me, almost sober. We laughed and talked and I was involved, included, enveloped in their friendship. She talked to me and to others, occasionally catching my eye and smiling at me. The last tiny ray of the sun caught.
