Christine and Kevin were having a casual evening at home. Their kids were at grandmas for the night and they invited some friends over to hang out and enjoy some adult beverages in front of the fire pit. The evening progressed nicely with Christine's ex, Fred being a part of their group, ending up being the last one to stay after everyone left. They've played with Fred in the past, this weekend he was in from out of state again and staying at a local hotel since they had limited room with the kids. Anyway, the three of them ended up on the patio enjoying cigars and bourbon on the rocks. Christine was sitting next to Kevin on their outdoor love seat. They were doing what couples do, by touching and rubbing each other knowing Fred didn't mind, and was probably getting excited watching Christine. At some point Chris decided to excuse herself to get another drink. She returned with drink in hand, and wearing a REAL tight black and white tiger print halter top mini dress with lots of cleavage showing.
"You boys like?" she said while doing a little twirl to give us a full view.
"WOW!!!" Fred and Kevin said in unison.
Christine proceeded to walk over to Kevin and kiss him long and hard while rubbing his crotch through his shorts while sitting on his lap, "Nice choice," he said to Chris, and to Fred he asked, "What do you think?"
"As always, very hot!" responded Fred.
As they continued talking Kevin was rubbing Christine's ass and every so often opened the cleavage of her dress to give Fred a peak at her magnificent tits. As stated before they had all been together before so this is not unusual behavior for them when they were together. Fred was visibly rubbing his cock through his shorts as he was getting more excited from the show Christine and Kevin were putting on. Christine noticed the bulge in Fred's shorts and knew how excited he was getting from watching her. She leaned her head on her husband's shoulder and whispered in his ear, "I'm so wet from what you're doing to me."
Fred stood up after noticing that the drinks were empty and offered to go refill them and went back into the house. Christine said that she was going to go help, winked at Kevin, and made her way back into the house as well.
