@Scottishcouple468 - Have a look at the thread Chastity Play / Experiment, it was one I started a few months ago but @rockstar and others also contribute
Last night, a session just for mrs sen with oral and strap on, my cage stayed on. Turns out she wasn’t feeling as she was feeling a bit sickly so didn’t orgasm. I still enjoyed making love to her with the strap on, lots of passionate kissing and touching.
