As Lilith babbled it made Liam blood boiled with lust. He couldn't help himself and continued fucking her while his face was showing that he was in full pleasure. His eyes were closed and his mouth was little open.
His hands had caught his mother's hands and whenever he fucked her and moved his hips, her hands would be stretched to his side while her breasts would shook from time to time.
Looking at her moving breasts, Liam moved his head and continued ramming her while he put his head on her breasts and started sipping her milk.
Feeling her milk in his mouth, he couldn't help but put his hands on her both breasts and started squeezing them lightly, as he squeezed he could feel the amount of milk entered inside his mouth is a lot compared to before and then he swallowed it.
As he swallowed an audible sound of gulping could be heard in atmosphere.
While Liam was doing all this Celestia was stunned.
