Anyway, on to an interesting experience that happened on a Sunday night a few weeks after our last fuck session together. About 9:00pm that night, Linda called Sue and asked if she wanted to come over and see some pictures from a wedding that we had gone to a few weeks before. Sue said, "Sure," and yelled down to me that she was going over to Linda's for an hour or so. I was watching a football game at the time and really didn't feel like moving so I didn't go with her; not that she asked. About a half-hour went by and I went up to get a drink and noticed that Sue had forgot to return their garage door opener (we had watched their house while they were on vacation), so I thought I'd be a nice guy and drop it off to them.
I parked my car in the driveway and went around to the back of their house as they are normally in their family room watching TV and was about to knock on the glass slider off their deck when I looked in and got a big surprise. The drapes were partially open and, as I looked to see if they were down there, I saw Sue and Linda sitting on the couch facing each other kissing. Both of them had lifted their tops up around their necks and were also rubbing their tits up against each other. I was in shock at first, but then slunk back away from the door so that I wouldn't be seen. I watched as they broke their kiss and Sue reached over to take Linda's pajama top off, and Linda did the same to Sue's top. They returned to kissing each other again and their hands were busy playing with each other's tits. It didn't take long for one of their hands to dip under the front of each other's shorts obviously to finger each other's cunt. Then, in turn, they each laid back and removed their shorts and panties.
By this time I had my cock out stroking it as I watched this hot scene. As I told you, their deck area was real private so I wasn't worried about someone seeing me. Sue turned around kneeling over Linda's face, lowered herself onto her waiting tongue and, at the same time, buried her tongue in Linda's cunt. I was getting hotter and hotter and at the same time they obviously had their orgasms, I shot my load on the deck. Maybe I was stupid not joining them but I really was fixated to the whole strange scene. This was the first time I was aware that they fooled around without Paul or I being there. At that point I stuffed my dick back in my shorts and went home.
Sue came home about an hour later and told me what happened. They looked at the pictures of the wedding; Paul and their daughter had already gone to sleep. When they finished with them it was like they both had the same idea and started to kiss each other. One thing led to another and they were at the point when I arrived very quickly. I told Sue I had watched them going at it and had left after their orgasm and had shot mine. She was alarmed at first that I'd be mad but I told her I wasn't and that I really enjoyed being a voyeur. Sue told me that after I left, they got out one of Linda's vibrators and proceeded to fuck each other's cunt and ass several more times. By this time I was hard again and we ended up having a great fuck session.
