Erza

When Wendy woke up, she was in a rather large room that she hadn't seen before. he dragged herself out of bed, but when that happened, she felt an enormous pressure on her chest, like it was really heavy. The sudden pressure made her fall down on the floor, painfully. When she got up, she noticed that the pressure on her chest came from a pair of very large breasts on her chest, causing Wendy to freak out that she somehow went through puberty overnight. She ran into the bathroom, only to be greeted by a reflection of Erza, wearing a pair of electric pink pajamas, minus the bottom which revealed a very thin black thong.

'Oh my god! I'm Erza!" Wendy/Erza cried inwardly.

What happens now?
