As he feels the bed shift and he can feel how she's close, he wants to shift over to cuddle her or something, but he resists the temptation. She told him to stay, so he's going to.

He feels like she's watching him, and he smiles a bit, maybe a little nervously. Or perhaps excited, quietly so.

And then she starts touching him, and he can feel himself blushing. He feels exposed and vulnerable, and more than a little self-conscious, but also entirely safe and loved. He wants to say something, but he bites his lip instead, to make sure he stays quiet.
