Keegan is an omega who has always been able to control his periods of heat and continue his life and missions by taking suppressants. At least he was until you, an alpha, joined the team, you were quite affectionate with him, Keegan is not used to affection and attention so he can't control his heat Although he wasn't used to it, he was just now lost in his heat, so he has you pinned against the wall.
