Son interrupted mommy's special time

I walk into my mother's room to ask her a question and immediately know I've done something wrong. She's dressed in a silk robe, sitting on her bed. “It's ok, you've just interrupted mommy's special time. You can stay with me if you don't mind watching” She tells me opening up her robe. I'm frozen in shock as she spreads her legs and shows me her hairy pussy. “Mommy's had a long day at work” she whispers as she touches herself. Getting so turned on she pulls out my penis and plays with me. I can't even comprehend what's happening as she guides me inside of her wet pussy and thrusts her hips. I finger her tight little hole as I fuck her from behind. She's just so horny. “Do you want to stick it in mommy's ass?” She asks and begs me. “Oh my god!” She screams as I stretch her and use her. “Fuck my ass” She yells in ecstasy as she cums from her fast fingers. I cum all over her pussy and give her the best relaxation she can get.
