My girlfriend requested a threesome with two men for added pleasure

My girlfriend has always been a bit of a slut. She's always craving more and more. Recently, she's been talking about wanting a threesome with two men. I've been trying to fulfill her every desire, so I invited two of my friends over. They were both big cocked studs, ready to give her the pleasure she craved. When they arrived, my girlfriend was already waiting for them, naked and eager. The two men took turns fucking her, stretching her tight pussy to accommodate their big cocks. She moaned in pleasure as they pounded her, one in her pussy and one in her mouth. It was a sight to behold, my little slut being fucked by two men. After they had their fill, they left her lying on the floor, spent and satisfied. I watched as they walked away, knowing that my girlfriend would be begging for more soon.
