They finished dancing and came back over to me for a drink. Jason was complimenting Zoe on her dancing skills, which led to compliments of her body. He then stated that he loves Zoe's ass and boldly spanked it right in front of me. Zoe bent a little and made an 'oooh' sound. She then went on to explain that she works hard on her ass in the gym and loves the compliments. Jason continued to push it and said the hard work shows whilst rubbing it slowly and spanking it again. Zoe was eating it up, she even turned to me and said "I can't believe you are letting your friend spank me." This stunned me a little, I knew she was joking because she thinks I like it, but the words cut through me. Before I could reply Jason said "not to worry, he loves it really." He then asked if he could see her toned ass, "as the hard work will look better bare." Before she could answer he had already began to pull up the back of her dress. He got it right to the top of her hips, exposing her sexy black thong to him. She just giggled away, having a blast but not stopping him. I saw a few looks from my friends across the room, they were grinning and joking, I guess at my expense. I wanted to just stop it, the humiliation, but I just couldn't bring myself to do it. Jason spanked her ass a couple more times whilst reaffirming that she had indeed worked hard on it. Zoe then stated "I don't know why I'm being spanked, I haven't been naughty." Jason just laughed and let her go. She pulled her dress back in place and continued to chat like nothing happened.
We went to the indoor pool area of the house. I'm sure we were meant to stay in the one part of the house, but being buzzed we couldn't care. I laid down on a lounger and Zoe sat on the end, next to my feet. Jason took his shirt off showing his ripped body. He asked Zoe if she wanted to take a dip. Zoe stated the obvious and said she didn't have her bathing suit. Jason pulled his jeans down and jumped in the pool exclaiming he didn't have his either. Zoe looked at me for permission, I said it was up to her. She smiled, stood up facing Jason, pulled her dress up and off and jumped in the pool. I was mesmerised by her body as she stripped, forgetting the situation, until she made a splash in the pool. Then reality set in and I realised that my enemy at work was now swimming with my girlfriend dressed only in a small thong. Jason commented on her breasts, saying they are the best he has ever seen. She thanked him, but disagreed saying she thought her nipples were too big. She stood in the shallow end lifting her boobs up showing Jason her big nipples. I love her nipples and never got why she thought they were odd. Jason came close to her to examine her nipples, he expressed his appreciation for them saying they are perfect. He asked "may I?" Zoe bit her lip and nodded whilst staring at me. Jason began massaging her boobs and playing with her nipples. Zoe was still looking at me, still biting her lip, she was super horny now. Jason began to suck on her nipples, she held his head to her chest and moaned. Eye contact with me was now lost. She had lost control. She was straddling him whilst making out, until my boss burst through the door. My boss started laughing and came over to me and slapped me on the shoulder saying he didn't know I was into that.
The moment for Zoe had gone and she wanted to leave. She smiled a thank you to Jason and proceeded to get out of the pool. Jason got out too and gave Zoe a quick swat on her ass and said next time you can help me get rid of this, pointing to his massive erection in his underwear. I gave her my jacket and put her dress in her bag. I thanked my boss for the party and we hurried to leave. Everyone else had gone home already and we got into a taxi for home.
Once we got home Zoe sat me down and apologised for going too far. She started to cry. I hated it when she cried, so I said don't worry babe, it's ok. Just to calm her down. But she took that as a go ahead. She thought I meant I was ok with what happened. She was happy again and asked if it turned me on. She stripped naked and knelt down in front of me. She got my hard on out and gave me great head. She got me on the cusp of orgasm and asked again, did it turn me on? I agreed yes as I needed release. She grinned and finished me off, swallowing every last drop.
The next morning in bed, Zoe was still asleep as I was thinking back about last night's events. I didn't know how I was going to face work, face my boss and worst of all Jason. He will be relentless from now on. Also on my mind was how Zoe will now be around my friends. Will her limits of flirting be much more now?
