This scenario has so much room for softness and vulnerability. 🥰 Caelus is so overwhelmed by his heat and what to do, and Aventurine has plenty of experience keeping his own heats under wraps and staying safe. He would usher Cae into a safe room / apartment together like a mother hen, comforting him the whole time and scenting him to calm him down. Did no one really teach him? It makes him angry but for right now, he has his sweet star to take care of.

Controlling his own needs and hormones will be hard seeing Caelus so vulnerable and soft (might even trigger his own heat if he's not careful, he's just too adorable aaa), all curled up in a nest they built together of his expensive clothes and bedding. He'll coo to him the whole time, taking the initiative to help them both cool off and covering him in kisses. His body is so hot and feels like its glowing with the Stellaron inside. He'll assure him he'll take care of everything, no need to stress his love any more. Just relax and let him handle it, cover him in love and soft markings.

He understands his anxieties and fears deeply from past worries of his own, and Aventurine isn't exactly the most used to being vulnerable with others. Not anymore. But, right now, with nothing but him and Caelus and a soft, perfect nest...He can let his inhibitions and fears of intimacy go. His hand is always on him the whole time, if not carding through sweaty locks then holding his own tightly or draped over his hip.

Aventurine would growl and hiss at any Alpha or trespasser for sure. No one is going to take a step towards their den on his watch.
