Stepsister fucking her new guy after I prep her

Dude, so this stepsister fucking situation went way beyond what I signed up for, because I ended up coaching her through prepping for her new guy and holy shit, she took direction like a champ, ass bouncing in that cowgirl position while I watched from the corner, her British accent moaning out broken words, then she dropped down and deepthroated me like it was nothing, spit everywhere, gagging but grinning, and I just whispered “go show him what you learned,” her big tits swinging as she rode him later while I caught her eye, that MILF energy hitting different when she swallowed his cum right after I came on her face, she licked her lips and winked, man, I still feel my dick twitch thinking about that buildup.
