The creature stands to its hind legs, bringing it's clawed hands to grasp the door frame. Rick stumbles backwards, running against the wall. He frantically turns and starts down the hall, fear driving him blindly.
Brandon launches into the hall, his nails clacking against the wooden floor, tearing up splinters. He skitters up behind rick and launches towards his back.
Rick feels nails scrape into his shoulder blades, then a weight topple him forward onto the floor. The weight pins onto his back, and he turns a frightened eye up to see the snarling muzzle. A hand greedily tears at the waist ban of his pants. With several violent tugs, he hears and feels the material give, soft hairs and burning stiff flesh suddenly against his skin.
Brandon guides himself up into Rick, driving his wanting flesh right up to his weighted sac. Growling pleasurably he draws back and thrusts. He pounds himself into his stepfather, who cringes and hisses beneath him. With wicked excitement, he buries himself deep into Rick. His body roars with life, needing release. It pushes up through his legs, and he howls, while deluging his stepfather's gut in his seed. He triumphantly locks his arms around his partner and pumps his cock till it ceases.
He dismounts panting. Flicking his tongue for a moment over Rick's shoulder before striding away and down the hall towards his familiar room.
