Girlfriend takes on big cock in garage

My girlfriend and I have a spicy arrangement. She's into being fucked by other guys, and I'm cool with it. We've been keeping it on the down-low, mostly in the garage. The other day, she brought home a guy with an absolute monster of a cock. I warned her it was too much, too big. But she's always been up for a challenge. She took it in her mouth, deep down her throat. Then she took it in her pussy, riding it like a pro. She's always been a fan of big cocks, and this was no exception. I watched as she got pounded, her moans echoing in the garage. She took it all, every inch of that massive cock. She even swallowed it at the end. It was a sight to behold. She's my girl, and I love watching her get fucked by the best.
