She may be telling you half truths. She may not be able to own up to the "full Monty." I have had this happen to me a couple of times. Said they just kissed, but later it came out that they were banging each other's brains out.
Be very careful. My first wife told me that grim details and then got naked and asked me if I wanted anything. If you take them up on it, you lose JW grounds for divorce. Just do not jump her bones after she admits that they did the deed.
All the above information only applies IF you care about the JW's man-made rules.
