"Hi Kaaren...um...your wife told me to...um ....to come see you. It turns out that my Mistress went home with someone and I'm kind of stranded here till she comes back to get me....so I was kind of wondering if I could...you know...sleep in here with you....your wife said it was OK with her if it was OK with you...."
"I only have a single bed you know!"
"Oh I'm sure we could fit in together somehow!"
"So am I, let me help you get that dress off..."
"Oh thank you! I'm not sure how I can repay you!"
"We'll work something out sweetie!"
