Family vacation can get extreme, when you have a sister like that. Once she sees her step-brother massive cock, she quickly hops to it. Taking it real deep down her slutty-ass teen throat. He feels every stroke and he can't even believe his luck. He cums incredibly quick, in two seconds flat. His step-sis is a swallower and that's also lucky for him. The two love-birds decide to escalate their forbidden passion. It's kinda awkward now and they decide to fuck on a bed, 'cause it's how it is from now on.
