Kate was incredibly turned on as she kissed her husband while in her sister-law's body. She was vaguely aware that Kerry (in Kate's body) was passionately kissing Michael (Kerry's husband). But to Kate at the moment the other couple were irrelevant. Kerry was just another blonde that Michael was kissing. In fact it was Michael she was thinking about even while kissing Tom. Ever since Kerry had hinted that Michael was 'Rather large' thoughts of her brother-in-law had barely left her mind.
Likewise Kerry was feeling very randy. She wanted to try out her borrowed equipment. And right now Michael was her best prospect. It was very exciting to be another woman. Her right hand had wandered down to Michael's crotch and felt his penis. Clearly Michael was excited as his bulge was rock hard. She started fiddling with his belt. She wanted sex right here right now. That Kate and Tom were in the same room as them was irrelevant to her.
Michael was also turned on by kissing Kate's body. Kate was a very attractive woman and the fact that his wife was driving that body at the moment made responding to the kiss morally acceptable. The dress Kerry - was this really Kerry? - was wearing showed off her long legs and slim figure. However he found himself constantly watching the other couple in the room over Kerry's shoulder. Tom was being seduced by a woman who looked exactly like his wife. He couldn't help but feel that Kerry was making him a cuckold. He found his hand taken by Kate's body and placed against her breasts. She wasn't wearing a bra. The breasts were small, just a handful, but the nipple seemed enormous. Clearly this woman was turned on.
Tom was also very aware of the other couple in the room. Of course he was enjoying kissing Kerry's body and felling her large soft breasts push against him. Like Michael though he couldn't take his eyes off the Kate body. The apparent Kate was grinding herself against Michael He wasn't sure how comfortable he felt about that. When he saw the apparent Kate fiddle with Michael's belt then place Michael's hand on her breasts it was too much. It looked as though they were going to have sex right here in the lounge.
Tom decided he had to stop the would be orgy. "Hold on everyone! We can't do this now. We have a dinner reservation. This will have to wait"
Kate reluctantly stopped grinding against her husband. She would have been happy to skip dinner and just take Tom to the bedroom but he was right. They did have a dinner reservation. She would savour an evening of anticipation.
Kerry didn't want to stop but Michael had enough presence of mind to see that Tom was making sense. He pulled away from Kerry's (Was it really Kerry?) kiss. "He's right. We can't do this now" Reluctantly he took his hand away from the woman's breasts and stopped her from undoing his belt. "Not now. We can do this later. In privacy" he told the apparent Kate quietly.
Kerry knew Michael was making sense, but it was hard to stop. It was only when Michael physically pushed her away. That she realised she was going to far. He was right. There was plenty of time for sex later. She glanced across at Tom and the brunette. They were both looking at her. She felt embarrassed.
Kate broke the silence "Let's go to the bathroom and fix our make-up" she told Kerry. Kerry was blushing bright red. Kate was aware she blushed pretty strongly. It was interesting see how her body responded to embarrassment from an outside perspective.
Kerry was particularly embarrassed to have been caught losing control of herself in front of Tom. She was all of a sudden very aware that she was in Tom's wife's body. He was such a nice guy. He didn't deserve to see this body acting like a harlot. She quickly responded to the invitation and followed Kate back to the master bedroom. Once in the door she closed it, turned to Kate and said "I'm so sorry"
"Hey. It's understandable. It's a real buzz being in your body. I had real trouble stopping myself as well. If I was married to someone as hunky as Michael I doubt I could have"
"You are married to a hunk. Tom is wonderful. He has such a perfect face and his voice is to die for"
"He's fat and short. But enough of that. I need to fix your make-up before allowing you out in public in my body".
"I promise to behave"
"Well save the kissing and sex till later. Remember we don't swap back until tomorrow morning. After dinner you can take that body home just don't tell me what you get up to"
"No kissing until we are back home. I get it"
"Okay get in there and fix my face"
