So over the last year the oh and I have been getting progressively kinkier and one of the things I like doing to her is tying her up and forcing her to come a lot more and harder than she normally would (she's pretty sensitive so wriggles about and pulls away nomally). I've got to a point where (according to her) she can't come any more without a short rest, it's like there's a barrier. I told her I'd like to push her through the barrier and her response was she doesn't think I'll be able to but she's happy for me to try.
I was just wondering if anyone else is similar and if anyone had managed to push through, and how did you do it? And if so was it worth it in the end?
