   Summary

   “Wait, I said it’s for tonight!” Giyuu holds his hands over his exposed underwear in protest, “I’ll be mad if you ruin it.”

   Sanemi pauses for a moment. His internal turmoil wreaking through his mind and body, both sides fighting for control. 'Stop and wait in agony while getting no work done, all while his husband walks around like a seductive temptress, or fuck now and beg for forgiveness later?'

   Sanemi believes that he is very good at begging.
