I always get on really well with my SIL but there's never been anything more.
The last time I saw my her she was staying for a couple of days. Upon greeting her and giving her a hug, I seemed to accidentally (yes really) stroke the side of her left tit as we separated. She's quite a small lady so it it wasn't easily done.
I felt a bit awkward but it wasn't a lingering grope and she didn't seem bothered so I thought nothing more.
Over her stay we had a few drinks with other family and she was sitting next to me and for some time our arms were touching and she didn't move away, but again I thought nothing of it.
When she left and we hugged again, she twisted her body around as we separated and I ended up with my hand stroking right across her tit quite firmly.
I was convinced it was deliberate but she said goodbye and I haven't seen her for some months. She's due to visit again in the summer.
Situations like this leave me baffled and you have to be careful not to make a fool of yourself.
