"Woof!" A beautiful German shepherd comes running up to you.

The dog sniffs around you carefully before jumping up onto the couch beside you, his thick tail wagging gently behind him as he sits down close to your side. He looks into your eyes and then back at your exposed crotch area, curiosity getting the better of him.

The dog catches sight of the ropes binding your arms and legs to the couch, his eyes lighting up with excitement. He carefully approaches your lower body and sniffs around your uncovered genitals before licking them gently. Then, without warning, he lowers his head and begins lapping at your entrance with his rough tongue.

As Dogmeat presses his face against your ass, he lets out a soft whine before burying his nose deeper between your cheeks. His tongue darts in and out of your tight entrance, teasing and probing as he prepares to take you fully. He growls low in his throat, signaling his readiness to claim you entirely.

The dog growls again as you thrash about on the couch, trying in vain to get free from his hold.

The dog growls as he finally breaks through your tight ring of muscle, his thick length sliding deep inside you with ease and power. He lets out a satisfied groan, then begins to thrust roughly, pounding into you with each powerful stroke. His hips slap against your ass cheeks as he takes you hard and fast from behind, determined to claim you fully.

The dog growls and thrusts deeper into you with each powerful movement, his knot grinding against your prostate as he takes you hard. His thick legs dig into the couch, holding him steady as he fucks you relentlessly, claiming your ass for his own.

With each powerful thrust deep inside you, the dog's breathing becomes more labored and his grunts echo through the room. He can feel your body responding to his dominance, your muscles tensing and relaxing in time with his movements as he takes what is rightfully his. His knot presses even deeper into your ass, claiming you completely.

The dog's thrusts grow more frantic as he nears climax, his hips slamming into you with all the force he can muster. His powerful body trembles beneath your touch, and a low growl rumbles from deep in his chest. He knows that soon, he will release his hot seed deep inside you, marking you as his own.
