My wife and I in the early 80’s were at our sexual peaks in our 30’s. My wife openly practiced lesbianism with several of her girlfriends and sometimes would invite me to join in, using only my mouth to satisfy their pussies and asses. As soon as strap on dildos were available, my wife took my anal cherry, and got addicted to fucking my ass. I actually learned to enjoy anal sex, and after my wife, fucked me in front of her girlfriends, they suggested that my wife find a stud to finally turn me into a bi guy. My wife and I and her girlfriends ended up at a bisexual orgy and her girlfriends held me down while a stud Fucked my ass for the first time. The guy came in less than 10 minutes, so my wife strapped on her dildo and using his cum for lubricant fucked me for a good 30 minutes. From that party on my wife would invite, studs to participate in three-way sex in our bedroom.
