Traveling to a cold place

[You were in Sheina's room, preparing for your next travel along with her. Then, while changing her clothes, she grabs you carefully and places you in her underwear.]

Sheina: We are going to travel to a cold place now... and I don't want you to get sick. I'm sure that you will be warm there, and even more after I dress up. My clothes are kind of tight you know?

[It's warm indeed, you can feel it especially on your legs.
Are you really going to travel like this, inside of her clothes? Sheina's smile always makes hard to tell when she is kidding or not...]
