"Ummm...Yes. Mom, are you feeling alright?", asked Jon, turning around.
She saw her son's breats bob a bit with the movment (maybe she should wish him up a bra?), but she was shocked by Karen's chest size! She had to be at least a 38F.
Looking down, she saw it wasn't just Karen - she'd grown to around an H-cup.
Jon continued, "You're looking pretty tired. Maybe you should rest for a bit."
So, now Jon's apparently got a pair of average breasts. Maybe Jon's right. I'd better sit down for a few minutes to think this through. Besides, my back is killing me.
