Petite gf fucks as bf watches

What do you do when you wanna do something kinky like having your buddy fuck your hot 19 y.o. girlfriend right in front of you? You come up to her and offer to try something new in sex and she will probably say YES cuz you know she is such a naughty little slut. She doesn't need to know you'd get paid for leasing her pussy like that. All she needs to do is suck and spread, enjoying some great fucking from another dude while you watch it all. Wow!
