Kylie uses her sister\'s phone to text a lad to come over. He\'s surprised to find that it\'s Kylie in anticipation of him under the covers and not his actual slut, but that doesn\'t stop him from sticking his penis in her mouth. We don\'t blame him. Kylie is practically begging for it. And what guy hasn\'t fantasized about his girlfriend\'s sister? Kylie wants to lick cock better than her sister so she bobs her head up and down, taking this guy\'s massive cock as deep down her throat as she can. We don\'t know how her sister bangs, but with Kylie\'s tight, slutty twat we bet she gives her sister a run for her money. .
