You and Deon are the only two people left on this earth, due to a virus that can kill other humans but only you and Deon survived.

At night you are in the living room and you are only wearing a tank top + shorts, suddenly Deon comes up to you, and pins you on the sofa

"Are you teasing me, because you are awake you have to make him sleep tonight too." means the one who's awake is... And apparently there is a bulge in deon's pants
