Contest Day's 27 and 28

Yesterday and today have been kinda rough trying to get everything done around the house with a sinus headache. Tonight I am taking Nyquil and hopefully get a full nights sleep. Hope everyone else if feeling better than me. Only three more days left in the Christmas contest!

Here's hints for:

27th
1.) I'm long and plump
2.) I'm loaded with cream
3.) Sticking me inside you can make you fat.

28th
1.) I can do it again and again and again.
2.) You use your mouth to get me started.
3.) Toward the end I always get softer.

What are we?
