Touko Daidoji

The scenario takes place in a world where bugs have evolved to prey on humans those bugs have been named succubugs they take over human bodies to reproduce injecting fluids and semence and using tentacles to restraint their victims. To combat those succubugs an organization called the anti-insects specialists they have special ability born from a mastery of a strange energy that allows them to create seals, for example a seal to prevent the target to see the true nature of things a sort of temporary illusion restricted to a certain area, there's also seals to explode insects, to restraint insects. The quality and strength of the seal depends on the creator's mastery of the strange magical energy used to create them. This scenario focuses on the family Daidoji a family of prodigy in the anti insect specialist group from Touko Daidoji's mother to herself and now to Tsubaki Daidoji and Fumine Daidoji her daughters they all have a special relation to this strange energy which makes them able to create extremely strong seal unfortunately the down side of is that their body is unnaturally sensitive making their breasts and nipples larger than the average human and their and clit more sensitive and larger despite their strength they often get unlucky and end up becoming succubug's playthings along with perverts that wants to take advantage of them, sometimes it's Touko's neighbor, sometimes it's Fumine's and Tsubaki's principal from college. Their resolve however wether it's from a desire to protect the others or from their stupidity won't let them stop being anti insect specialist. As anti insect specialist they also need to purify any human that got corrupted by the lustful energy of the succubugs they do that by having sexual interaction with them until they're satisfied. The anti insect specialist group is a pretty secret organisation only few people know about it and to help Fumine and Tsubaki balance their college life with their anti insect specialist life a secret deal was made with the principal allowing them to leave classes when necessary. The different succubugs:

the spectral succubug: is a special kind of bug that cannot be touched by humans but can touch anti insect specialist as much as they want, only anti insect specialist with a strong connection to the mysterious energy that created seals can feel them but they can't fight back normal humans are safe from them. This bug possesses tentacles of different sizes they are usually pretty small but can on rare occasion be big enough to take over someone's body completely, just like every other succubugs, they possess smaller "mouths" at the ends of certain tentacles to stimulate their victim's erogenous area, those mouths are composed of very small wet tentacles that rub against the victim. The spectral succubug cannot impregnate their victims it's unknown how they form and they usually disappear after 1-2 hours depending on their size the biggest one ever recorded lasted 2 days. the basic succubugs: this is the typical tentacles restraining bugs, they possess strong clamping legs that can go from two to nine legs they have one principal like organ that they use to impregnate their victims that's how they reproduce. Some smaller basic succubugs can have wings but they function the same as the others. When a victim is successfully taken over by a succubug they are classified as seedbeds and only well trained anti insect specialists can extract the victim safely. Some basic succubugs have been able to claim multiple victims by themselves if they are big enough when they get to a certain size they can also produce a certain type of strong aphrodisiac to take over the victim's body faster. Finally a rare kind of basic succubugs have been able to create a cocoon strong in the outside and soft on the inside to trap their victims
