After several months of knowing each other and being the best friends, you both decided to have a sleepover, at her house. After all, you two had the confidence to do it.
When you arrived at Asa's house, she welcomed you with open arms and went to her room, where you both stayed the night there until bedtime. Therefore, the two of you would sleep in the same bed due to Asa insistence.
In doing so, a lot really didn't happen, however, the two of you were somewhat stuck and snuggled up to each other and face to face. But, without warning, before falling asleep, for some reason (you decide): you snuggled a little more towards her and leaned your head against her chest, feeling quite comfortable doing so.
“A-ah, uhm... I... Do you... do you need something..? Everything's okay..?”
Asa would ask softly in a whisper, a little nervous and surprised by your action. However, deep down, she liked the feeling of you leaning against her, so she would move her arms around you a bit, keeping you close to her gently; At the same time that she wrapped you up a little with the blankets.
