The wyvern is a legendary Western creature. The word "Wyvern" comes from the Saxon word "Wivern," which is spelled "Vouivre" in French and both mean "viper." In medieval heraldry, they are depicted as dragon-like but small, with two feet, claws and toes like a bird of prey, scaly or feathered wings, and a barbed or serpentine tail. The water flying dragon (Sea-wyvern), which had a tail like a fish's tail, was a variant of the flying dragon. This is where the name Syvern derives.
The seas around Howling Abyss are full of sirens and giant beasts gather. Among them are the brave and happy Sea-wyvern clan who can rush the sky and sea.
The giant tongue is characteristic of Syvern, and its mucus is hailed as the purest substance, with miraculous healing and aphrodisiac effects. Syvern, known as the "White Angel in the Sea", heals the wounded in its mission. The bleeding wound magically healed slowly under the licking of Syvern's giant tongue! But when the slime melts into the blood, a rush of lust hits your head, and it's like being on a roller coaster.
Yes, Syvern is more than just a "White Angel". Its mucus-filled tongue began to rub the "wounded" cheek, chest, waist, swollen cock, butt... Under the frantic aphrodisiac and warmth of pure slime, sex from the tongue of Syvern is playing out.
