Secret of Treasure Box

An adventurer explores a deep dungeon in search of loot and eventually discovers a promising treasure chest. However, the chest is a trap set by a succubus named Miku, who is using a mimic's body to ambush unsuspecting victims. Once the adventurer approaches, Miku springs her trap and captures her prey. The succubus then uses her tentacles and aphrodisiac saliva to sexually assault the helpless adventurer. Ultimately, Miku successfully extracts the adventurer's 'nectar' to feed her own desires.
