First thing I'd do is to cover them with my mouth, then tease them with my Tongue. Then just to make sure they were back to that Perkyness I'd slid my Hard Cock between them and let some Fiction warm them up for a bit. Of course I'd then have to cover them with some Cum for Protection. Gently place my entire mouth over them and breath. Then lick them lightly but just enough for you to feel the sensation. Now I have a question. Why on earth would I want to warm them up when they look divine just as they are? Wrap my large warm hands around each of those gorgeous tits and place my mouth on each nipple alternating sucking and nibbling till they are really hard. I would massage them with my hard hot cock. Hopefully that would warm them and keep the nipples perky. Shall we try? I'm sure a nice hot load would warm them up. Then using the head of my cock to rub my cum all over your sweet nipples.
