I got a boner while kissing my blonde girlfriend

My sexy blonde girl couldn't stop thinking about my cock. So, while her step-parents were dancing in the sitting room, she sneaked me into her bedroom and gave me a passionate kiss. My girlfriend enjoyed kissing me so much that her pussy got wet. So I had no choice but to lick her pussy. My girlfriend then gave me a blowjob and let me fuck her pussy doggystyle.
