After pumping so much cum into Tony they both laid on the floor of the locker room trying to recover from the transfer.
As Chad lays next to the mountainous coach next to him he notices that his body begins to inflate once again.
Beginning to panic he tries to roll himself over and get up but he is too exhausted.
Soon he had filled once again to the size he was before he filled Tony but Tony was no smaller.
Once the transformation was complete both Tony and Chad were able to stand belly to belly.
That was the moment when a twink by the name of Byron came into the locker room and his jaw dropped as he saw the two behemoths standing in front of him. That they could stand was one thing that he recognized them as being fairly normal weight not long ago was another bit of awe. He hadn't seen Chad in awhile but he was the muscle god he lusted after.
As he came closer the two parted like the red sea and Byron got between them asking them what happened.
Neither Tony nor Chad responded with any intelligible answer to Byron as he looked back and forth between the two he noticed that they had moved in closer and closer until he was wedged in between the two.
Just the mass of the two was able to knock the breath out of Byron and even though they couldn't reach past their bellies they were able to lower Byron onto a nearby bench and Chad took Byron's mouth and Tony took Byron's ass bending him almost in half to access his hole under Tony's belly.
As the two worked him over Chad began to lose his fill once again watching Byron fill like Tony had. But Tony wasn't losing an ounce. He remained massive as Byron became their size.
Now while Tony and Chad had been jocks Byron had never worked out in his life. The fat distributed differently for him. He was more pear shaped. His legs filled out as did his arms. His man boobs rested on a grossly sagging belly. He no longer had a neck where as Chad and tony had double chins upon double chins. When he sat up he had rolls looking like a real life Michelin man.
The great weight that Chad and Tony now sported was more pronounce in their bellies but their arms and legs were also very thick showing a lack of recent workouts.
If Tony and Byron tried they might be able to work off the tonnage but Chad would always return to that size after infecting others.
But Byron and Tony would realize that their bodies were much more sensitive and enjoyed sex much more at this size when they could find someone to have sex with.
