All Force-users have wings, upon using their abilities for the first time. Usually this is when they are young, but due to her life on Jakku, Rey's first use of the Force is during the interrogation scene with Kylo.
Its slow, painful, and terrifying (if somewhat more natural-feeling) for her, and although Kylo is anxious himself at witnessing it, he knows this is his chance to convince her to let him teach her, if he can ease this process along for her, the most formative event of Rey's life as a Force-user.
So, with lots of tender touch, careful application of the Force, and whispered guidance, Kylo helps give Rey her wings.
Bonus: Clumsy use of her wings during her escape after interrogation.
Bonus +2: During their final duel, Rey's newfound confidence in her wings takes their battle to the sky.
