... Of course no one was wasting any time explaining things to Ami. She wasn't in the habit of dressing without "foundations." Admittedly the shorts were too short for the kind of over-the-hip thongs Jason had supplied during the day (and maybe they were the only kind he had) but no bras under the T shirts?
... Admittedly the T shirts were tight and a bra would be obvious but ...
... It looked like they were to go out, in public. Not only would their breasts show through the material but ...
... Going without would eventually ... but then he'd already talked about surgically implanting a kind of bra. (And if over the years her boobs sank more? A larger shield?)
... But why was Ami worying about people seeing her breasts? They were going outside. That might just provide her with the opportunity to escape. Though Jason must be certain somehow that they wouldn't or he wouldn't take them. But the opportunity would be there.
