Rex was about to be homeless, already having to spend a night on the streets before he got an offer to stay with a couple he knew. Rex was ecstatic. He had played with them before and was happy to accept their generosity, willing to do anything to have a place to work things out. It wasn't until he moved in did he learn the conditions of his stay.
He could only ever wear a jockstrap around his waist while he was in the house. He was to keep his ass shaved and prepped while he lived there, allowing anyone who came over to use him. The only furniture he was allowed on was what the couple called the dog bed- a sofa covered in a comforter. This would go on for as long as it took him to move out, otherwise he'd be kicked back to the streets.
Rex was scrambling to find a job. He was applying everywhere he could, but it didn't take long before his bed was covered in his own and other's fluids as he was used. He never thought of cleaning it. He wanted to use it as a motivation to get him back on his own feet, but in the back of his mind something was changing.
Each time he was fucked and passed out in his filth, he felt himself growing more accustomed to it. Soon he was used to the smell of sex engrained in his bedding, the scent of sweat and cum clinging to his skin. It felt so good, so natural he began to look forward to being used each day.
He began to think of the couple as his owners, needing them, wanting them to take advantage of him. Each time they did his drive to look for work decreased, feeling more and more at home. Soon the anticipation of being fucked overwhelmed his thoughts, completely eroding his desire to find a job. All he did during the day now was lounge on the couch with his ass out, waiting for his owners to use him.
It didn't take long for his new owners to notice, happy to come to a new arrangement. In exchange for an allowance, he'd be their new house boy, cleaning the place after them and allowed to spend his time how he saw fit. Rex agreed immediately. Even though he was now free to use the rest of the house and wear what he wanted, he still chose to go around in the house wearing only his jock, spending the nights in his bed unless his owners wanted him in theirs. It wasn't long before there was party to celebrate Rex as their new house pup, everyone invited there getting a turn to use him.
