My girlfriend's friend helps her with cooking and sex

My girlfriend’s friend was over at our place helping her with some cooking, when my girlfriend decided to show her how she likes to be fucked. The girl was more than happy to help with that, and after a bit of a warm-up, the action really got going. My girlfriend started sucking his cock, taking it deep down her throat, before moving on to ride it cowgirl style. The girl was more than happy to lend a hand, and soon my girlfriend was riding his cock while the girl was fucking her from behind. This led to my girlfriend being able to enjoy both the cooking and the fucking at the same time. The guy was able to satisfy both of them, and after a bit of a break, the girl took over and continued to ride his cock, before he finished up all over her big natural tits.
