It is a pretty obviously terrible line, but Ianto doesn't mind. In fact, at this point he's almost sort of charmed by John's terrible come-on's. He's not quite certain what that says about him, but he's not going to let himself think about it too closely either.

His lips curl further, hands slipping back around the other man's waist to hold himself steady against John as he grabs him tight. He supposes it's not a huge loss if the food is forgotten at this point. They've both eaten a fair portion of it at this rate, and a handful of cold fries is no great loss in the long run.

"Perhaps if it will help you sleep..." Ianto muses, continuing to rock him gently from side to side as he does. "I think we may be able to come to some arrangement. For your health and wellbeing, of course."
