My Healing Love (Omegaverse)
But it was also the first time he felt his mind exhausted after sex too before it was the contrary, that happened, his mind was always awake and clear after sex.
Maybe it was because of all the feelings he had while Max was making love to him. All the suppressed emotions he'd buried in his heart to stay strong when he was away from his son and his lover, the longing, his suppressed love, his suppressed desire, all of it suddenly came back to him at Max's very first touch, and with all those feelings, coupled with the ecstasy he felt as Max buried himself inside him, he could not help but feel tired at the end.
