His head moves readily backward with her tug, his lips falling into her kiss again. A small noise of surprise escapes him as she takes hold of his cock, followed by a softly exhaled moan. It's strange to feel someone else's hand on him, hers small and using pressure differently than he would. It's exciting, though. He imagines he is supposed to reciprocate, so he slides his own hand between her legs, pressing palm and flat fingers to her warm and wet groin. He's unsure exactly how to do it or what might feel nice (there isn't even porn in his world to learn from, really) so he just presses and rubs there a bit with his whole hand for now.
