The best orgasm I ever had was from a girl and her real sister fucking my well lubed asshole with a glass buttplug that they both had in their pussies and buttholes . The older sister fucked my ass while the other one straddled my throbbing cock and just sit there not moving. She said she was waiting for her cream pie. She didn’t even move up and down. The stroking of my prostate made my shoot the most cum I ever have! It ran out of her for hours afterwards. I still Jack off to that memory!
