The next Sunday, when Steve and Jane arrived at Richard and Katie's house, there was no pretence of painting or watching movies. Both couples immediately paired off and disappeared upstairs to the bedrooms.
The sex had been good, Jane told herself as she lay in Richard's arms. Good, but not great. Something had been missing. And then she realised that what was missing was the excitement, the danger of getting caught. When she and Richard were making love in his studio, there was always a risk that Steve and Katie would walk in on them. And Jane realised that was what made it so exciting to be with Richard.
As Jane lay there thinking about this, she heard Steve and Katie making love in the next room. Katie was making a lot of noise, and Jane pictured her riding Steve's cock, with her tits bouncing up and down as he fucked her. The idea of watching her husband fuck another woman excited Jane. And then she realised that she didn't just want to watch, she wanted to join in with them. The thought of this made her very horny, so she took Richard's cock in her hand, stroking and fondling it until he was hard enough to fuck her again. And as they fucked, Jane imagined that she was with Steve and Katie. She came hard, harder than she had ever done before.
Later, after they had all returned downstairs, Jane and Katie were in the kitchen fixing some drinks.
"You know, I really regret that I made Steve return that sexy underwear that he bought for me," said Jane. "I've been thinking that I might buy some myself. Do you think that you could help me to pick some out?"
"Of course," said Katie. "We can do it this week if you like."
So the following Wednesday, both Jane and Katie thought of an excuse not to go to work, and they went to a lingerie store in their town. Katie suggested several items, and they walked over to the change rooms. "Come in and help me try them on," said Jane. And so they both went into the change room.
In the change room, Katie held the underwear while Jane removed her clothing. When she was completely naked she turned to face Katie. "My, my, you are a big girl," murmured Katie approvingly. "Steve's a lucky man."
Jane could feel Katie's eyes on her body. No woman had ever seen her naked, and the thought that she was completely exposed to Katie's view made her very excited. Then Katie helped her to try on the underwear, and the touch of Katie's hands on her skin made Jane tingle in a way that she had never felt before. Suddenly she wanted to see Katie naked as well, and to look at her in the same way.
"You should buy something too," said Jane. "All right, I will," said Katie, and went out of the change room back to the store. Soon she returned with black lace panties and bra, stockings and a suspender belt. "What do you think?" she asked, holding them up. "Mmmm, very sexy!" murmured Jane approvingly.
