I parted her robe the rest of the way and started licking my way from her nipples, watching them harden, down to her mound, which wasn't shaved but her pubic hair was sparse, giving a neatly trimmed appearance. She was fresh from the shower and I loved the smell of her skin, nothing to mask the slightly musky scent of her pussy. The more I lapped and nibbled at her, the hotter and wetter she got, and I was aching to slip my hardon into her. I got up on the couch while she worked John's dick, and worked my own into her, amazed at the whole affair in general and the hot wetness of her pussy in particular.
It wasn't long before I was alternating between enjoying the moment and concentrating on baseball scores, pictures on the walls, anything to keep from losing my load too soon. The long strokes and the sight of her writhing and taking one of us at each end was about all I could stand. She must have come three times by now and didn't look like she'd stop any time soon.
Soon John let out a long groan and started shooting his wad into Ginger's throat and it was all the encouragement I needed. I threw one of her legs over my shoulder, plowed in till my balls were mashed against her ass, and started to blast my own juice deep inside her with a long gasp.
After a few minutes I caught my breath and quietly slipped away for a quick shower. When I came back into the room they were lying on the couch and grinning at me. "Thanks," they both said, to which I replied, "No, thank YOU!" We all had a quick laugh and I left.
We've all seen each other since that night, either at work or at the bar, but we've never repeated the performance or even talked about it. That's just as well. If it happened all over again I still wouldn't know what to make of it.
