Tied succubi (Pixiv Fanbox)

Demons are notoriously difficult to train, as they possess seemingly infinite stamina and lust. Our trainers however did find a method to turn even those creatures into obedient trainees who’ll do just about anything to receive pleasure. These two succubi have been tied together using blessed rope, making it difficult for them to escape. They’ve been force-fed extremely strong aphrodisiac every few minutes until their bodies started shaking and twitching from the mere thought of being touched. Around their necks is a chain, just long enough to keep them from choking as long as they’re holding still. Now they’re completely overflowing with lewd juices. However, the two of them will have to remain like this until their minds are completely broken.
