David propped himself up on one elbow and said, “You know. It’s totally cool if you ever want to have sex with another woman.”
Mary looked back at him sharply, “Why would I want to do that?”
“I’m just saying. If you wanted to, you could… as long as I get to watch.”
“That’s very generous of you.”
“I do what I can.”
“And you could have sex with another man, if you want to,” Mary said, “as long as I get to watch.”
“But you go first.”
David pretended to consider this offer before lying back down.
