We had known Phil and his wife, Ann, for a few years. Ann was away for the weekend seeing some old school-friends so we had invited Phil out for a meal and a drink. We invited Phil back to our house for a nightcap and I went to the kitchen to prepare some drinks. While I was in the kitchen music started coming from the living room, nothing raucous, just something quiet and relaxing. I was bit surprised when I returned to the living room to find Sue and Phil dancing to the music.
The dancing was more of a smooch really. Phil had his hands on Sue's waist and had pulled her close. Sue had her head on his shoulder and they were moving together very well. When I offered them their drinks they looked a bit sheepish as they broke apart and collected their glasses. We all sat down, Sue and I on the sofa, Phil on a chair and discussed the evening and what Phil's wife would be doing now.
I admitted that I found Ann attractive and would happily take her out on a date if we were both single. This resulted in Phil saying how much he liked Sue, to which I replied that it was fairly obvious from the way they were dancing that Sue liked Phil too. Sue gave me a slight punch / nudge but didn't deny it. Well, before the conversation got too heavy Phil finished his drink and said it was time to leave.
The music was still playing so Sue stood up and instead of saying goodbye, offered Phil a goodnight dance. Of course Phil was too much of a gentleman to refuse and they started swaying to the music. Within a couple of minutes they had moved closer together and they were more or less in the same position as when I had brought them their drinks.
As they continued to dance one of Phil's hands moved down to Sue's bottom and seemed to pull her closer. Sue didn't object and when they turned so that Phil's back was to me, I noticed that she looked very comfortable with her head resting on his shoulder. While they were in this position, with Phil's back to Sue's eyes suddenly opened and she emitted a slight moan. When they completed their turn so that Sue's back was to me Sue's skirt was hitched up slightly and Phil's hand was underneath it. I knew that Sue had worn a thong for the night out so I assumed Phil was having a quick feel of Sue's bum before he headed off home.
A slightly faster song started playing and they moved slightly apart but continued to dance. While they danced Phil was trying to look down Sue's blouse and I knew that as I had noticed Sue was bound to have too. Sure enough she moved towards him and rubbed her breasts across Phil's chest. He was a bit surprised but quickly recovered and happily stood his ground, allowing Sue's arousal to increase and her nipples to become visible through the blouse. Phil leaned in and pulled Sue close to him again. He glanced across at me possibly expecting some reaction but I just smiled and gave him a slight nod.
They continued to dance and the hand I could see again made its way down to her bum and he started caressing her cheeks. I was getting more turned on by the second and was wondering how far this was going to go. We had never really discussed involving anyone else in our sex life so we were definitely pushing back the boundaries even though it had not gone very far yet.
I went to get another drink for myself and I deliberately took my time to see if my absence allowed things to progress. When I returned and sat down again they had turned around and Phil's hand had risen and was in the middle of Sue's back. The beat of the music changed and they moved apart. Phil started to slide his hand round towards the side of Sue's body and moved it up until he was just touching the side of her breast through her blouse. Phil then stretched his thumb out so that it reached around to the front of the breast and stroked across Sue's nipple. This elicited a groan from Sue.
I was fast coming to the conclusion that Sue was becoming so aroused that she would be willing to take things to their natural conclusion. I suddenly felt a bit unsure about that but as I'd not stopped them at the start I decided to go with the flow. Of course the alcohol I had consumed probably had something to do with that.
