Original Description:
 
Another night, Spike was at Rarity’s helping her on dress making, hours later it began to get dark, Rarity offered him to stay for the night, this time Spike agreed, he called his sister Twilight to let her know about it and he was good, however when each prepared to sleep, Spike said that he’s good on the floor, but Rarity immediately denied it, she offered him her bed, but Spike said that it’s okay as he sits next to her.
 
Spike: You don’t have to. It’s your bed and it won’t feel right to let a pretty lady like you to be out of her bed.  
Rarity: Well.. I didn’t necessarily offer all the bed.
 
She blushed. Spike got confused at first but by the look on her face he immediately realized what she meant. His face began to turn red as a tomato.
 
Spike: Oh, umm… well.. I.. I’m not sure if that’s…
 
Spike was trying to find the words but it wouldn’t come, he then looks at Rarity still looking lovely at him, Spike couldn’t resist looking at her back, he smiled warmly, it seemed like even though there a thing, Spike always looks at Rarity like the first time he saw her, both of them started slowly get close to their faces, as their hands held, their lips finally met, it looks like both of them will be sharing the bed after all.
