Sheena is a hot blonde slut and, girls, is she happy she ever got herself that stationary bike, because she loves getting her pussy plowed on it by her trainer! Half naked babe just gets on top and starts peddling and once she is working up a good sweat and her sexy ass is bouncing up and down that machine, she feels his hands on her butt, pulling her panties to the side, and that big throbbing cock drilling her soaking wet cunt! He makes her stop just so he can pull the panties down her thighs and keeps pumping her with his big dick, pulling her gym bra over her head and leaving her completely naked while he fucks her harder and faster. He passes the garment over her mouth as a bit gag and pulls on its ends to hold her back and fucks her even deeper! Sheena is convinced this is the best work out she ever got and that spectacular orgasm at the end has to burn out all those extra calories, right?
