*laughs* Tony in the Batman t-shirt is just inexplicably cute (or maybe that's an effect of his "WTF, ew" face at the taste of the granola bar).

I love Steve's back and shoulders and Tony's neck, in the second pic, and Tony's hand in Steve's hair (and expression; it looks like Tony has a thing for Steve holding him down, too, which doesn't surprise me at all). And schmevil is right - the pillow is great.
