Family of Love, and fun...?

There is a stallion named Flaming Scribbler and a changling named Crystal, they love each other alot and they have two children by far.

Fire Wing is a changling, he is funny, shy, and passionate around others.
Pink Paint is a filly, she has a little but serious condition, she is in heat almost 24/7 but she hasn't known about it yet. She is gullible, funny, not shy, and usually quiet.

The two lovers love to have fun, so much fun, that we had put it in a story. As of now, im gonna explain the entire story, from the beginning and it goes like this...
