Castiel's Little Sister SPN

Going Shopping

Dean offers to take me to a place called "Calvin Klein" and Cas says I can go. On the way Dean's hand snakes up to my hip then comes back down and holds my hand in his. When we get there he takes me to the back, and asks for a female helper to get me sized. Then he kisses me on the cheek, and says he'll be back in 20 minutes or for me just to call him if I need anything.

Once I'm sized and wearing a new bra, Dean comes back and helps me pick out a dress. It's black and white and middle thigh length. Then we get me some running boots, and some flats for the dress. His hand is on my thigh the whole way home with his thumb making little circles on the outer part of my leg.

We walk in the house to see Sam laying on Castiel's chest and Cas running his hand through Sam's hair. Sam and Cas look up in shock and Sam rolls off of Castiel. They were both blushing. When Sam sees Dean and I holding hands, he smirks at Dean causing his face to flush.

Sam- "What did I say Dean?"

Dean- "I, um, well, nothing yet."

Me- "Sam, what did you say?"

Sam-"Well (Y/N), I told Dean not to get you knocked up too soon."

Both Dean and I blush, and he lets go of my hand.

Castiel- "Um.. well that's awkward."

Sam- "Soooooooo, where were you guys? Out buying protection?"

Dean flips him off, and calls him a female dog.Then Dean went to his room, and once he comes back to the living room, I told him that I'm going to the bathroom. When they aren't looking, I sneak into Dean's room. I sit on his bed and just listen to what they were talking about. The only thing I can hear is Sam yell at Dean about him having protection if he does anything stupid. 'What kind of "protection" are they talking about' I think to myself.
