I asked her how the party was she replied with "It was fun... perhaps a bit too much fun" as she looked at me with a sexy smile. This was it. She was going to tell me! She started to tell me the story of their party but I stopped her, fixed her a drink and let her continue. She said that her and Bill had left the party after what she thought was a meaningless kiss but when they got up to go to the car, she caught a glimpse of his slacks and the large bulge that was showing. Something stirred deep inside her and by the time she got to the car and they had kissed again she just could not stop herself and she reached down to place her hand on the cloth keeping his cock inside and ran her hand across the solid shaft of a hard dick and by that time she knew she had to see it... and maybe even touch it.
She said he had not forced her to do any of this and she even paused for a moment before she continued to remind herself of our agreement that if either of us has an affair, to discuss it with the other. By this time my hands were rubbing her blouse on the couch and her nipples were hard and firm through the soft shirt and bra. I asked her to continue and she then told me about how her touching him quickly developed into what she felt from his response must have been one of the best blowjobs she had ever given, or maybe his wife just doesn't do that for him. Anyway, she said that what seemed like 30 seconds later he was straining, holding back and then exploded into her mouth as she buried her face in his lap. His cum was very, very warm and tasted a bit different than mine but she seemed to be proud of herself for swallowing all but a couple of drops.
Bill then thanked her and asked her if she would like to go somewhere to continue the party and no doubt was hoping for some more but she insisted that she had to get home because I was waiting for her and besides, by now her pussy was so wet and ready to be fucked she could hardly stand it. As she tells it, they then drove to the office garage and swiped the badge to open the gates. Driving in Bill must have been thinking about the quiet empty garage and after making it to her car on the level 3, parked the car next to hers and she said he reached over and kissed her very softly (her favorite way). Once again she felt something inside of her stir and she wondered if he had noticed the scent of her aroused pussy because he then reached down and gently up her skirt to caress her warm and moist lips through her panties. She was in heaven and parted her legs and shifted a bit to where she said her back was against the car door and she was facing him. She must have had her eyes closed and moaning as I have seen and heard her do many times.
