A horny girlfriend gives a blowjob and has sex with me in a sexy bikini

I'm not exactly sure what's going on here, but things are definitely heating up. My girlfriend, who's probably around 18 or 19, decides to give me a little surprise. She's got a thing for my friend's cock, and she's been dying to give him a blowjob. So, when she's over at my place, she just goes for it. I don't mind, of course, and she does a pretty good job. But then things start to get a bit weird. Apparently, my girlfriend is a bit of a secret prostitute, and she's been trying to get my friend to take her out for a while. And now, it seems like she's finally managed to do it. So, after giving my friend a quickie, she's ready to get down and dirty with me. We start off with some hot kissing, and then she starts to strip off her sexy bikini, revealing her amazing ass. We move on to the bedroom, where she gives me a nice, slow blowjob before taking my big cock deep inside her.
