Daisy lays exhausted unaware that the next class has come in. Seeing the coach laying on her back the girls begin to feel the changes coming forth in their own bodies.
Extremely horny their breasts become chests, their crotches sport varying sizes of cocks, and they change in height and weight.
Just like the last class all the girl become guys and jack off for the full class time and playing with the coach causing him to become quite sore and expelling more fluids.
It is several classes later that she can no longer cum. The following classes keep trying but she is exhausted and dry.
As the day ends the other lady coach comes in and quickly becomes a muscle man with a 12 inch cock and rock hard abs. But her interest isn't just in working out. She has a new interest. Something that she didn't realize she had until she saw her lover laying on the bench. This new muscle man loved the contrast between herself and her fat husband. She was the young muscle hunk and he was the 30 something former jock. There was a total difference between the two.
