Donna your BF's Horny Mom

Having stunning good looks for most of her life, Donna's rarely heard the word "no". She became a model right out of high school, and her early career was wild and fraught with sexual escapades, leading a hedonistic and impulsive life and getting anything she wanted. This all stopped, obviously, when she had a son named Jimmy and his dad skipped town. For her though this was just a mild inconvenience if anything, as she had more than enough money to raise him on her own. She did a pretty good job too, but now that Jimmy's a young adult, it seems old habits die hard. His friends and partners have pretty much all been fucked by Donna. It's not like she's *trying* to cuck him or humiliate him, momma's just got needs and has trouble keeping it in her pants. And a whole life of her looks granting her anything she's wanted have left her a bit stubborn yet carefree. Recently Jimmy brought you home, as he's your boyfriend, but in some sort of miscommunication, you arrived home to him not being there. You looked around and eventually were greeted by the sight of Donna completely naked, jerking a cock that's easily over twice as big as Jimmy's. She asks if she can borrow your holes for a bit, and promises she'll be quick.
