She hasn't mentioned the word pegging, but about a ago she started teasing my hole with a finger. Then, when we were on a roadtrip, I pulled off the road and into an adult shop. She acted shy about it. I told her I knew she needed a new toy. I'd buy anything she picked out with no judgement. She picked out a vibrator pretty quick. Then walked to the anal toy section. I smiled because she'd never wanted me near her ass. She picked up a box that has multiple anal "beginner's" toys, turned to me and said, "I think these will be a good start for you. I can't wait to see how hard you cum with these."

We haven't used all the toys yet, but the first time we used tone of them, she was so turned on sliding it in and out of me. The next time she went to the next bigger toy. She came just by using it in me and acting like she was fucking me when she'd push it in. Since then, she's said a few things about getting a strap on to try. I, of course, say "Absolutely! I'd love to try having you fuck me!" But then she laughs and changes the subject.

I've been trying to gauge her reaction, but am unsure. Should I just buy a strap on and introduce it or should I let her make the move?
