From my experience, I think you should enjoy all she is offering but total “hands off” unless she initiates contact. I had a similar situation with one of my girlfriends (now wife) sisters. I didn’t know if she was “coming on” to me, testing me or just being totally naïve. She was younger and prettier then my GF and I had seen her in a variety of half naked poses up until then.
I was only 19 at the time and would have fucked anything that moved with a pair of tits. I wanted to get into her pants so I came up with a plan to “test” her. Normally when I would see her in various exhibition poses, I would make a joke or if my GF wasn’t around, I might pay her a compliment. (Nice undies, Lucky boyfriend etc,). She would usually just smile or laugh and continue dressing or undressing.
I decided to feign total indifference to her exhibitionism and judge her reaction. The next few times she appeared in underwear, I turned away (as if bored) and watched TV or became engrossed in a book. I did everything to show her that I was indifferent to her charms. I continued with this tactic for a couple of weeks. The end result was that she did nothing different than usual and showed no annoyance or even acknowledged that she noticed my unusual lack of interest. The signs were obvious. She wasn’t trying to bed me, she was just a little naïve and didn’t seem to realise that her actions were having an arousing effect on me.
At this point I should have backed off and forgot about her but I was only nineteen and considered myself a sex god as I had had sex after all with TWO women. I didn’t back off, Instead I put a plan into motion that set both of us alone in a room working for an evening.
During that evening I made a move on her. At first she thought I was just flirting but soon realised that I was serious when I began to kiss her and fondle her tits. I got a pretty big shock when she pushed me away and told me to back off. She was horrified that I would try to make out with her while dating her sister. She told me plainly that she had no interest in me and never would have.
The rest of the evening was pretty embarrassing for both of us and we hardly spoke for weeks afterwards. My relationship with my sis-in-law did suffer and took a long time to recover. There was no more underwear shows or sneaky glances as she always left the room if she had to change. Years later I think she told my wife that I was having an affair with an employee of mine.(which I was).
