The back end

Ian looked at the monstrous penis twitching right before him, he could tell that the stallion was exited, which scared him since he could easily take advantage of his situation. So Ian chose to avoid his massive penis completely, which meant he had to choose the back end. „I'll...take the back end...” Ian murmured ashamed.

„Fantastic!” Tony exclaimed still happy.

He grabbed his shorts from the ground and pulled them up to his knees, before slowly turning around so that Ian could see where's he'll be staying. His eyes widened when he saw how big the stallion ass cheeks were, they were literally bigger than his torso, they were so big that he couldn't even see his asshole between them, just a squint dark crack. Ian could already detect an awful smell coming from them, as well as the smell of equine sweat mixed together, making a horrendous air that almost made him throw up. Still, Ian was a little happy of choice, as he thought being in the front would be way worse. He took a glance up at Tony, who was looking back at him smiling, eagerly waiting for him to settle in for the ride.

The small kitty took a deep breath of the clean, outside air, before finally building up enough courage to get closer. Carefully, he climbed inside Tony's black shorts that were still held by his powerful hands. He made sure to get into a comfortable and manageable position between his thick legs, while keeping his eyes upwards and the giant ass looming over him. The black shorts were somehow already sweaty and sticky, Ian's body stuck to the thin fabric like glue, but he didn't not comment on it to the horse since he knew it would get a lot worse pretty soon.

With Ian settled in the stallion's underwear, Tony wasted no time in pulling them up entirely, Ian's chest and head getting buried directly between his brown ass cheeks, while his legs somehow managed to reach and hug his massive ballsack. Ian's entire upper body was squished together by the two massive lumps of flesh, barely being able to see or breathe anything, which he wished he couldn't, since the air he had **** but to inhale smelled horrendously hot and rancid, and his eyes were prefixed at the doughnut hole of the horse that seemed excited to have a roommate. His feet could also feel the horse's excitement slightly, as his ballsack kept moving slightly.

Tony kept on smiling, grabbing his shorts a few times and wiggling his butt to get Ian even further up his butt. Once he was satisfied, he looked in to a mirror, and observed how well the kitty settled in his black boxers. Looking at his massive rear, he could barely see a small bulge in between his big ass cheeks, while his crotch had a little weird lump under his ballsack, but he doubted that anyone will notice it once he sits down. Tony, the stallion whined satisfied, having completely hidden the kitty in his boxers to keep him safe as he wished, and because how good the cat felt squished between his ass and his tight pants. He admired his work for a few moments, moving his hands across the small lumps made by Ian in his shorts, then wiggling his butt trying to make them disappear.

Ian wasn't sure whether to consider this better than being inside someone's belly, or worse, his body was entirely squished together by a sweaty ass of a stallion and he hadn't even started working out, he could only imagine how worse it would become. But he wasn't in the right to complain as he chose to be stuck in the back, and tried to remain positive that he won't be stuck there for a long time. His head and torso got squished harder and further by the stallion, almost getting close enough to kiss his nasty black doughnut. He could feel that Tony had begun moving, with each step one of his massive cheeks squished Ian into the other cheek. Ian felt like he was being tortured, having **** but to have his face be buried in the flesh of his ass cheeks while he walked.

Eventually he stopped, Ian thought that was a good thing, but the moment Tony sat down, his head was squished further, bringing his face just a inch away from his smelling doughnut that seemed super eager to give him a wet kiss. Thankfully he didn't feel much pain or the weight of the stallion when he sat down, only a part of his legs and butt were slightly affected by his weight when he took a seat. Ian couldn't really tell what was going outside, or what Tony was working on, his head was too deep between his ass cheeks to hear anything from the outside, and he barely cared as his eyes watched horrified at his doughnut hole slightly twitching with excitement, and sweat starting to appear on the stallion rump, making the air even hotter and smellier. Whenever Ian tried to move, or wiggle slightly, the horse wiggled his butt against him, pushing him back to where he was.

Ian could tell that Tony was more than enjoying his company while he worked out, he thought he could even hear him giggling whenever he clenched his ass to bringing him closer to his ass hole. While safe, Ian could tell that he was at the mercy of the horse, and that he was treated as his ass toy, which made him think whether this was all worth it.
