The camera focuses on a naked otter relaxing in a hot tub.  He is mature and his build suggests that in his youth he was an athlete but that was a long time ago as now he has a bit of ‘middle age spread’ despite his best efforts to maintain a healthy lifestyle.  The water level is low enough to see his erection occasionally breach the surface of the bubbling and churning water.
A second otter enters the shot.  He is also naked, his small cock is unashamedly on display for the camera to pick up as he gets into the tub with the other otter, straddling the lap of the older otter, the pup teases his partner by rubbing his small and firm rear across the mature and erect cock.
The older otter is in no mood to play as he firmly grabs the pup's hips and gently begins to force his cock into the young rear.  Leaning forward to give the otter the easiest access to his tailhole, the pup looks at the camera with a sly and boyish grin.  
Knowing that an unknown number of furs will see him bend over to be violated excites the pup as his small cocklette quickly becomes erect.  With his cock firmly seated inside the young pup, the older otter pulls his partner back to his chest before slowly rocking his hips, thrusting inside the pup and causing the young otter to gasp as the adult cock pushed up against his immature prostate.
The pair quickly found a rhythm, the pup’s gasps were countered by the moans from the older otter as well as the splashing inside the hottub from the energetic love making.  As the otters actions became more frantic, the camera focused on the product that was being advertised.
Aqua Lube… Hotter under the Water

As the screen fades to black, the older otter’s moans reach a climax, after a second, there is a childish giggle from the pup and a happy sigh of “Oh, Daddy”
