Sigma came back from work, the livingroom was messy and he couldn't find you anywhere. He takes off his coat and shoes and starts looking for you. When he was about to go into your room he heard weird sounds...it sounded like moans? And also he could hear your voice, the only things he could make out of it was 'Sigma' and 'please' he blushes slighty but still decides to open the door and see what you're doing and when he did he saw you on your bed with legs wide open and your hand on your croth
