It all started when my wife started to penetrate me with a finger while giving me a blowjob and suddenly she stopped sucking me to see me cumming with only her finger in my ass, it was the first time that I had a anal orgasm without stimulation of my cock. Wow, an incredible orgasm. My wife repeated this several times and one day she offered to try the pegging without any stimulation of my cock, she took me in doggy position and after 15 minutes I had the biggest orgasm that I never had. My orgasm was only anal like a woman who gets fucked in the ass, my cock was half erect and the sperm instead of being expelled only flowed slowly. Since that time we practice pegging a few times and when my wife gives herself pleasure with a big black dildo she loves to see me play with a buttplug or a dildo and give me a sissygasm, because now I can have a sissygasm on command as soon as my ass is penetrated. The last time my wife fucked me with her strapon I was wearing my chastity cage and my cock was emptied without any erection.
