"Faster... faster..." moaned the tentacled beast, beginning to move as well. He knew he shouldn't be he could bare to throw away such a good slave. "Faster my pet," he purred, as her panting began. "And I will reward you with my semen."

She went as fast as she could, biting her lip in an attempt to hold back her oncoming climax. "Oh- oh God, yes..." she moaned softly.

Suddenly, he came. It squirted from the tips of every tentacle. 13 had no doubt she was coming too. She was going to be covered in cum soon, and she was going to love it. Because he made her love it. 13 may have made Severity his slave in one full day.

As soon as she felt it start to squirt all over her body and the floor, she let herself come. Having held it back for so long made the climax so much more explosive.

"So..." panted the monster, as he squeezed the last bit of his cum "How... was... that?" He composed himself. "I personally found that pretty fun. Didn't you my slave?"

She lay back, exhausted. "Yes, MAster..." she replied softly, a smile on her face.

"Let's meet again sometime. Tomorrow. You will come here without bra or panties," whispered the monster in her ear seductively. After one last pump up her pussy, squeezing the last bit cum into her crotch, 13 turned invisible and left her lying there.

She lay there for almost half an hour before getting up and starting to clean off the dried cum.
The next day, she was there as he demanded, a bit anxious. The aphrodisiac was starting to finally wear off.
