When the Buizel girl saw that Ty was asleep, she took the opportunity to look around, and she saw a set of legwarmers on the table. She knew that Ty would love to find the nude girl wearing legwarmers in his bed when he wakes up, so she proceeded to adorn the kinky attire and carefully scoot down into position next to Ty on his bed~
But what happened next she never expected! Her modest chest started swelling in the most unusual way, and she saw her breasts were growing larger to sizes she never imagined for herself!
The Buizel girls started getting worried, but she was not sure if waking up Ty would be a good idea anymore since this new development started to make her feel guilty like this whole plot was a big mistake. She pulled off the legwarmers, and she was happy to see this stopped her breasts from growing, but when she saw that the breasts remained so large in size, she knew Ty was going to find out about this intrusion easily later.
So she stayed silent for several more minutes, trying to think what she had to do... either wake up Ty and explain what happened, or try to sleep and hope things will be okay when Ty wakes up later... or, when she looked to Ty and saw that nocturnal erection, fantasized about sexual methods that she could do to entertain the both of them~
It was later revealed that the fibers of those legwarmers came from the same kind of plant that grows the "Breast Fruit", as described by
