I instinctively slipped my hand up her tiny vest top and placed my hand on one of her naked breasts, praying she didn’t feel I was taking it too far...and stop me. To my delight, she let out a pleasurable sigh and guided my thumb and index finger to her nipple. The kissing gradually got slower and came to a stop. Nikki sat back, looked me up and down and bit her lip. “Well, that was unexpected...” All I could do was nod in agreement. I was still in a state of shock. She took a swig from a beer. No reply. By 6am I was worried and tried calling, it rang and then went to answer machine, I left a message.At 7:30am I heard the front door open and footsteps gingerly walking up the stairs. I lay in bed and watched her come in looking cold an still tipsy. I asked her why she didn't reply and why she was so late? She mumbled some answer about taxi's and then said she wanted to shower.I got up from the bed and walked into the en-suite as she turned the water on. Gripping her waist slightly. I. She stopped by a bench and I ran up and stopped for a breather and a stretch. After some pleasentries she told me how horny she was and didn't like to be out after dark on her own so I invited her to run with me for company. We ran back round the park and out along the seafront towards my hotel. I couldn't believe this was the same woman who I'd been talking to about licking hef asshole hours earlier as she looked so innocent and unassuming. Not many women could look that good in Lycra Yoga.
