Nice!! Alex is ready to be a grandfather to Lana and Daniel's child. The trip will be a good opportunity for Daniel to knock up his mom.
Fifteen years later Lana's once curvaceous body now running to fat, big tits flopped down like empty saddlebags into her lap, her pussy run dry and all desire spent, Daniel fucks and impregnates the sister-daughter he fathered with her, subsequently fucking and impregnating his daughter-granddaughter and so on, down the generations, until impotence intervenes and puts an end to his career of abuse and familial incests.

Kneeling beside his mother's grave, an old man now with tears in his eyes, fetid urine trickling down the insides of his wet and incontinent thighs, having never known the tender joy of fucking a willing girl or woman unrelated to him by blood, he cuts his throat with a butcher knife in remorse.

As he slowly bleeds to death, Lana's grave yawns open before him. A horde of fiends and demons emerge, dragging him screaming to the Second Circle of Hell—like Christopher Marlowe’s Faustus—as punishment for breaking the laws of God and man in life.
Amen. Finis. It is the end.
