Mark
He’s not very bothered by it. He knows you prefer to go without while you’re at home. It’s a bit like a middle ground since you don’t mind his ‘morning wood’.
JB
He’s said that he’s always wanted to cuddle his wife/girlfriend while she sleeps, and because bras are the worst to sleep in, he’s perfectly comfortable with you taking it off while in bed. He would hold you a little tighter than usual though.
Jackson
“Tee-hee-hee~”
He’d find it kinda funny at first. He isn’t used to the feeling, but hugs of all kinds are welcome in his book.
Jinyoung
“Uhhh.”
He would be the most embarrassed. A blush would creep onto his cheeks and he’s starting to smile nervously. Even when you ask him if he’s alright, he’d get all giggly and nod.
Youngjae
Of course, you back-hug him all the time, but the second he feels your nipples on his back, he turns into a deer in headlights. He would be so caught off guard, but make the best of it and turn around to hug you properly.
Bambam
He would revert to a shy baby the first time you cuddle him without a bra. He doesn’t want to give into his urges and make you think he’s a perve so he’d just go with it and try not to let you see his reddening face.
Yugyeom
He doesn’t have a lot of intimate relationships with girls so he might get a bit… excited when he feels your full breasts through the material of your top.
