"It's Liam. It's Liam sitting on Sam's cock." was my instinctive reaction. PEOPLE SHOULD FEEL FREE to get more creative with it than my kneejerk brain, but omg. It's just so easy to picture. Liam would LOVE that. Imagine him crooning like he usually does about how sexy and compelling Sam is, playing deniability all the while the audience doesn't know how utterly and earnestly Sam's dick is inside him. Trying not to let his voice crack!!! The heat of the recording booth is even more intense when Liam's split open like this. There's sweat rolling down his neck but he's going to keep his voice steady for the recording. Imagine SAM introducing Liam flippantly - "Liam O'Brien, your wife and mine," - while he's balls deep with Liam squirming on his lap.
