Going on a bonding family trip with my older stepsister I had no idea we'd be bonding like this. She came on to me and offered to deep-throat my dick, just like that, as a bonding experience. Unnecessary to say we both loved it so much fucking seemed like the most logical way to continue it. Man, I fucked my hottie of a stepsis so good and tight her slurping slit just exploded with a powerful orgasm with my big dick still inside. Fucking greatest idea ever.
