Our relationship changed after Fred fucked Janet, during our weekend at the motel. Fred had to work Monday, but was invited to dinner Tuesday night. When he arrived, Janet greeted him at the door wearing a white teddy. Her nipples, ass and bush were clearly visible through the material.
As we sat down to eat dinner, Fred reached over and undid the crotch snaps, exposing her bush and ass. After finishing dinner and cleaning the kitchen, Fred suggested we go out for dessert. We agreed.
Janet said, "I'll be dressed in a minute."
Fred said, "You already are dressed."
"You want me to go out wearing just this teddy."
"I'd like you to go out nude, but the teddy is fine."
I agreed with Fred.
Janet put on a raincoat, to get to the car. In the car she took it off.
We decided to skip dessert and take a walk on the beach. We parked the car and got out. Janet wanted to wear her coat but I dared her to leave it in the car. She smiled at me as the three of us walked away. As we walked Fred reached over and pulled her shoulder straps down. While he held them Janet pulled her arms out, leaving the straps hanging at her sides. Further along I reached over and pulled the top down below her tits.
