This came a bit unexpectedly

Rainbow Dash and Soarin were both on a date and they were talking about everything.
“Have you considered the future?” Rainbow Dash asked.
I am and I already know what I want. “Said Soarin smile on his face.
“Well?” Rainbow asked.
“I want to be a life partner with a beautiful pony mare, Equestria’s best pilot.” Soarin replied and looked down at Rainbow Dash.
“Who is she?” Rainbow Dash asked annoyed.
“It’s you. You want to be my special pony?” Soarin asked and handed over to Rainbow Dash.
Rainbow Dash blushed.
“This came a bit, but I can, and I want to.” Rainbow Dash responded and put his hand on Soarin’s hand.
