Elderly stepmother confides in me privately

As a young guy, I've always been close with my stepmom, who's a bit older but still hot as hell. She's got a big ass and a fat, juicy one too. One day, she confided in me privately, telling me about her unsatisfactory sex life with my stepdad. She's been craving a big cock and some real action. Being the good son, I offered her my cock, which she eagerly took. After a quick blowjob, she let me fuck her tight asshole, moaning and begging for more. It turns out, my best friend has been fucking her too, and he joined in, pounding her ass while I ate her pussy. We gave her the wildest anal creampie, leaving her satisfied and me with a huge smile on my face.
