She tests the world pen on Matt.

Using the pen Cathy wrote able to have sex twenty-four hours a day with no negative side effects on Matt’s skin. Looking at his dick she giggled excitedly as the red skin started to look less raw. She waited, watching until it was back to normal. Then using the pen, she wrote the same thing on her own arm. After the ink vanished, she felt her sore muscles start to relax and her pussy started to heal. Giving Matt a hungry look she climbed up onto the bed and mounted him.

“Ms. Marks, please think about this. I’m sorry I refused you, but this isn’t the answer.” Matt pleaded as his supervisor slowly impaled herself on his cock.

Cathy moaned as she started to bounce and said. “It’s too late Matt. Your going to be my little breeding stud from now on.”

Matt pulled at his restraints to no avail as he struggled to find a solution. Looking at Ms. Marks he tried a compromise. “What if you use the pen to make me have to impregnate you whenever your fertile? Then you won’t have to keep me locked up. It’s going to take years for you to catch up on your quota.” Matt bargained hoping she would limit it to that before freeing him so he could try to get the pen from her.

Cathy slowed her bouncing as she considered his proposal. After a minute she smiled wickedly and said. “I have a better idea.” Using the pen, she wrote able to give birth to a perfectly normal child every week with no negative consequences on her stomach. Matt’s eyes widened in horror as he watched the ink vanish. “Now I’ll be caught up in no time at all.” Cathy remarked as she started to bounce faster again.

Matt slammed his head back into his pillows resigning himself to wait for an opening. After a few hours of constant sex, he noticed a change in Ms. Marks appearance. Looking closer he noticed her belly was a little bigger. Seeing the funny look on his face Cathy looked down to see what he was staring at. With a delighted squeal she hopped off him and got down from the bed to get a better look at herself.

“This explains why I have been feeling so hungry lately.” She said as she marveled at herself. Leaning over she planted a loving kiss on his dick. “Good work.” She whispered before she excitedly ran out of the room.

As Matt looked around, he noticed the world pen laying on the bed. Stretching his hand out he tried to reach it but couldn’t. Matt strained with everything he had, grunting as he exerted himself. His fingertips brushed the pen when a form darkened the doorway.
