A pen that writes and seals Charm Spells

This pen is filled with hypnotic charm magic.

By using this item, succubi can directly engrave the seal of slave contracts onto their targets' bodies, and unilaterally conclude them.

A person who has such a seal engraved on them will be filled with blind love for the pen-bearer, and will not disobey a single order they give.

Caution : The edges of the seal will feel to the victim as an injection of raw pleasure !

Fufufu <3
Does it feel so good you can't move ?
You should be careful...if you don't do a better job resisting, I'll be done writing very soon...~

Do you hear this ? You're about to become my *slave*~

A cute little slave who loves me sooooo much <3
Who will do aaaanything I ask <3

Isn't it wonderful ?

And when I do...the spell's seal will be complete...and the charm will come into effect...
