Noir promptly fell asleep after they were done, and Solis watched his little darling of a husband with tender eyes for a long, long time with a silly (and very satisfied) grin on his face. After that, realising that things would get a bit awkward if he didn't clean up now, he quickly gathered Noir in his arms and went to the bathroom.
Noir seemed to have been completely tired out by their rigorous 'exercise' just now – he didn't wake up at all while Solis cleaned him up and changed the sheets and tucked him in, and then Solis cleaned himself up as well and climbed into bed, cuddling with his sleeping husband.
The young couple woke up a few hours later.
It was actually Noir who woke up first, his stomach rumbling. It had been a while since they had eaten, and after spending so many calories earlier, it was quite natural for Noir's stomach to make its condition known and demand food!
