Reverse pegging

We do.  Our WLM is based in, among other things, orgasm control/denial and 24/7/365 (mostly) chastity.  Mistress K. has no interest in giving up penetration, while also having no desire or interest in cuckolding.  She solved that dilemma 18 months or so ago by establishing a new standard whenever we have sex that includes penetration.  The default is now that whenever she wants penetration, she picks the dildo she wants and has me put it in the strap-on harness.  Being experienced with orgasm denial, it has made our sex amazing.  Another nice little rule she put in place ... if I can orgasm while fucking her with her favorite rubber cock, I am allowed to do so without having to ask permission.  It's happened 3 times, and it's fantastic.  

@subhubphx I’d suggest that if you’re going for extended periods without release, it might be worth finding a urologist who understands your lifestyle, just to help you avoid any prostate issues later on. There are prostate toys out there that could help, ones you could use while you’re using the strap-on, making it easier and a bit more enjoyable to stimulate things at the same time. Cheers!"
