On the way to Karyn's house, Ted sent a lot of glances towards Jon. So that he wouldn't be too undressed, Ted gave Jon one of his T-shirts before they left. Jon's D-cup breasts were straining the tight shirt and giving Ted something interesting to look at while he drove.
Jon didn't particularly like Ted looking at him like that, but he was getting a ride to Karyn's house, so maybe he could put up with a few leering glances.
Unfortunately, there were more than just a few glances, which was the reason the car accident happened. Ted was keeping his eyes more on Jon than the road and didn't see a car backing out of a driveway.
Ted was basicly okay, but Jon had to be taken to the hospital. When the ambulance came and the paramedics tried to get Jon out of the car, his body began to change once again.
