"Yes, I'll be your wife. Besides, I've loved you all my life."
Ty chuckled, as Rebecca had already rhymed, despite not yet being a fairy.
"You already are speaking like a true fairy, so please, won't you take this berry, so we can go home and we can marry?"
Rebecca took the berry and ate it quickly, and with a flash of light, she began to sprout butterfly wings, her clothes ripping away, exposing her modest C cup breasts and making her completely naked. She shrunk to Ty's size, and fell into his arms, her flower dress not appearing, leaving her completely naked.
Rebecca opened her eyes to find herself in Ty's arms, instantly noticing something was amiss. "Oh my gosh, this is all a mess, why didn't I sprout a flower dress?"
Ty blushed a deep red, his nose starting to bleed. "Admittedly, I know it's rude, but I really wanted to see you nude..." Rebecca also blushed a deep red, then began to giggle. "This was a little scary, but we are about to marry, so it feels a bit better to be a nude fairy." Rebecca turned around and pushed her breasts to Ty's chest, causing his nose to bleed even more, and his penis to erect. "I really think that we should wait, until after the wedding for us to mate. Besides, aren't we still only 15, because sex does feel a little obscene."
Suddenly, Rose Bloom came in through the window at the most convenient moment. "Ty, I think this may come as a jolt, but you are both 18 now, technically adults.
Also, she will after all be your bride, Rebecca, my dear, will you stay by Ty's side?" Rebecca nodded, as Rose Bloom made a flower dress sprout from her naked body. Rebecca look between the two fairies, and made a connection. "I believe you are Ty's real mother, so tell me, was Ty looking for any other?"
Ty hugged Rebecca a bit tighter. "You are the only girl I've held in my heart, and I hope we'll never be torn apart." The two fairy lovers kissed, the first kiss they had ever shared, as Rose Bloom carried them with magic back to the castle.
