Ms Jensen tests her invention on Rocketgirl

When Rocketgirl awoke she found herself bound to a table. Her arms were restrained stretched out from her body and above her head, and her legs were restrained at the ankles spread wide and bent at the knees. “Oh no” Rocketgirl noticed that her costume, except for the cowl that covered her head had been removed and she was naked except for it. Looking around she noticed that she was in a room that was probably a basement, there were only a few small windows and the walls appeared to be soundproofed. She noticed a table and a cart nearby with some medical equipment, syringes, vials of liquid, and other things. She also noticed a belt with a large strange looking strapon. The strapon appeared to have a set of testicles which had a cap on them.

Rocketgirl lay helpless in the room for about 30 minutes contemplating what was going to happen to her until she heard the door open. In a moment Ms Jensen came into her line of sight wearing only a robe. As the young heroine watched, Ms Jensen had her back to her and picked up the strapon. The older women appeared to fasten it to her waist. Turning around, Rockeetgirl could see the tip of the strapon poking out under the tie holding Ms Jensen’s robe. Rocketgirl struggled harder against her restraints seeing the smile on Ms Jensen’s face.

“You won’t get away with whatever you have planned, and you will be destroying your career.” Rocketgirl said.

Ms Jensen started to stroke the strapon as if she was materbating. “You don’t even know what I have planned.” She said with contempt. “And my career, if this works it will make me millons more than I was as a college professor. You see I have invented a synthetic sperm for impregnating women. Do you know how much there is to be made in cases where a woman wants to be pregnant but her man is infertile?”

Rocketgirl tried pulling her arms free and then tried hooking her fingers to open the restraints. “But aren’t there already methods?”

“Yes but those methods do not always work. See my synth sperm will be much more potent and have a longer life, guaranteeing that they reach the eggs and achieve fertilization.” Ms Jensen grinned. “I just need a test case, and you have volunteered to be my guinea pig.” The older professor opened her robe and let it fall to the floor. She was naked underneath, her large sagging tits were clearly visible as was her belly and her cellulite thighs. Ms Jensen moved between Rocketgirl’s spread thighs and started rubbing the tip of her strapon against the heroine’s slit, lubricating the college girl. “Just relax and enjoy it, you are going to help me make medical and scientific history!” The graying haired woman then started to push the tip of the strapon into Rocketgirl…..
