What's next?

Erza in Natsu's Body

Waking up groggily the next morning Natsu finds herself in what looked like her own home, looking to the side though proves she most definitely was not alone.

"EEEEIIIIIIHHH!?!?" she screamed her voice hoarse from the fact her former body was to the side. the former salamander gets punched by her old body and as it stirs the rest of the way and stands up naked and erect the former Titania asks only one question

what does she ask?
