A curvy woman pleases me while my girlfriend watches

I've got a smoking hot girlfriend, but she's got a naughty side. She loves to watch as other women pleasure me. This particular night, she brought over her best friend, a voluptuous beauty with a body made for sin. She's got curves in all the right places, with big, bouncing tits and a fat, juicy ass that begs for attention. She wasted no time, getting down on her knees and taking my big cock deep into her mouth. Then, she bent over and presented her ass to me, inviting me to take her from behind. I did just that, pounding her hard and deep, while my girl watched, her own body responding to the sight. The action was too much for her, and soon she joined in, using a dildo on herself as she watched me fuck her friend. The sight of two women getting off while I was the cause of it all was enough to make me shoot a load all over her fat ass.
