Chase had a rough day at school. He was sweaty from all the heat and PR. When he returned home school from the bus, his deodorant had run out.

"Chase, you stink" his father said, rising from the couch, "let's give you a bath."

"O-okay."

They both walked to the bathroom. Awkwardly, Chase took out his clothes, standing naked before his father, who was testing the shower water.

"Okay, it's good to go. Hop in."

Reluctantly, Chase stepped into the father. No soon than water run through his fur his father opened the lotion and began to apply the shampoo to Chase's delicious 10 year old body. He rubbed him all over: his shoulders, his chest, his tail. But gradually, more and more the older otter would settle on the child's calves and buttcheeks, passing them suavely. He kneeded on the buns, exposed Chase's pink butthole and washed it over, spreading it apart. 

The father could hold it much longer, and he turned Chase's tail to the side, and began rimming him.

"D-dad!" Chase said, before moaning.

Soon, his body convulsed, and he had a dry orgasm.

Chase's father decided to turn off the shower, and pick up his precious little otter over the shoulder, too weak to fight back. Going to his bedroom, he picked some towels and put them over his bed, too impatient to dry his son. He threw him to the bed, and before he could crawl away the father laid on top of him, his belly putting his in place.

Maneuvering a little, the older otter lined his dick with his cub's still somewhat gaping hole.

The bed creaked as his thrusts began to pick up. Chase, trapped, could only moan in slight pain, but he was quickly driven to a series of small dry orgasms.

After fifteen minutes, his father pulled out and crawled his to his son's face, unloading ropes upon ropes of cum unto him.

"Fuck... you need another bath..."
