Sam was pretty sure he was going to fail the challenge of keeping his eyes on hers. He was already blinking hard and each time he thrust into her (and he was doing that faster and faster) made his eyelids flutter and made him moan just a little bit.

He couldn't even really feel his hips by now as they were on automatic, just thrusting and thrusting out like clockwork. He hadn't looked away yet but he wasn't going to be able to look much longer.
