First time pegged

[Malesubslut33]

After a long time I finally spoke to my vanilla wife about my kink sub side. At first she was a bit taken back but after sitting down and chatting and explaining what I liked she has said she is happy to try pegging with me. We have played with prostate toys and I have done solo anal play on the last but can I have some advice for my first time lol. She has said she wants me to be on all fours. We have chosen the following for her to use. She didn't like the idea of a harness so gone with this combination. I also didn't like the idea of a realistic looking dildo.
