By the sixth day, the influence of Long ZhenHai's and Hu Lijing's estrus waned little by little as the amount of time they spent in fortification decreased. Still unable to return to civilization until their estrus was fully resolved, they simply chose to find amusement with each other.
Personally, Long ZhenHai's favourite activity for amusement was kissing which ended with them fucking together all over again, much to Hu Lijing's chagrin and his body's dismay.
Not that he refused the dragon's advances.
These days of vulnerability were the only time when Hu Lijing would ever let Long ZhenHai seem him unguarded, walls down and completely relaxed.
Sometimes they would spent hours on end in the warm sea water, sometimes they would spent it soaking in a nearby spring — don't ask him, Hu Lijing had no idea where this spring came from — while Long ZhenHai would show off his treasure collection to Hu Lijing, preening with delight whenever the fox praised him.
