3rd POV
Alec walked into the apartment hoping Magnus would be to bed by now so that he could crawl in with him and surprise him. He was relieved to see that all the lights were off. Alec maneuvered his way down the hall way to his boyfriend's bedroom where he could see the light on under the doorway. He sighed, disappointed and was about to open the door when he heard a moan. Magnus must be jerking himself. Alec reassured himself and was about to turn the knob again.
"Ah…Magnus" Said a voice that was definitely not his boyfriend's. Alec was now panicking. Is he cheating on me? No! He wouldn't do that. He loves me! Alec thought to himself. Alec turned the knob and pushed the door open quietly and what he saw in the room broke his heart.
Magnus was hovering over a boy with greenish tinted skin, and blond hair. Magnus was between the boys legs and they were both bare ass naked. It was obvious that Magnus was fucking the guy due to his continues pelvic thrusts and the moans that were escaping both of their mouths. He's cheating on me! Alec thought as tears rolled down his cheeks.
"Right there Mags! Ughh" The green skinned boy moaned.
"You're so good to me Sam…" Magnus said biting onto the boys shoulder and that's when the other boy saw Alec but he didn't say anything.
"M-Magnus?" Alec asked, his voice breaking from the tears.
Magnus's movements stopped completely and he froze in place for a second before turning around and facing his boyfriend. Magnus's eyes were wide and he looked almost scared to see Alec in his doorway. Alec had a flow of tears running down his cheeks and his eyes were rimmed with red. "How could you do this to me?" Alec sobbed before running out of the apartment.
Magnus pulled out the boy he had been fucking only moments ago a rushed to pull his pants on. "Leave." He commanded Samuel, before running after Alec, not caring about the boy and hoping he would be gone by the time he got back.
