I used to do this with my best friend when we were young. We got caught by his mother in the basement and she made us suck each other's cocks and then she got naked and had us sucking her tits and licking her pussy and asshole. She got us hard and we both fucked her and she showed us how to fuck each other and lubed up our asses. We still fuck to this day and sometimes go over and fuck her too. She's 76 now and still very kinky
