A dual pic of a dragoness called Fern, she's was a normal dragoness before encountering Kilara ( http://www.furaffinity.net/view/9100017 ) by then she was cursed to grow into a giant or macro, then she met Rapier (my main), she gained control over her size and returned back to normal, though on occasion, she will grow again, mostly on her own accord or through the curse she got

Edit: there is another part of the curse she got is that she is unnatually busty and curvy

first pic is that she is undergone a growth spurt due to her curse so she is more trying to limit damage while she grows before shrinking back down

second pic is herself thinking about her love Rapier
