"Tides of Restraint"

Prompt: Cronus and kankri from homestuck. They have been matesprites for a while but have not had sex due to kankris vow. Kankri is pining and can’t think about anything other than Cronus naked. Kankri has secret gills but no one has ever seen them since he hides them under a turtleneck sweater. Cronus is a sea dweller troll and has his own gills. Cronus is build like a Greek god with a slutty waist and is very respectful of kankris vow. Kankri comes to Cronus’ hive unannounced and sees conus swimming nothing but skimpy bikini bottoms. Kankri fights to keep his hands to himself.
