Ultramom is made to cum and provide her sperm to the female scientist

“So you say you haven’t always been like this? You haven’t always been a shemale?” The female scientist said as she cupped Ultramom’s balls in her hand and squeezed them.

“No, I was a woman before yesterday, I had a woman’s organs.” Ultramom said. “I was battling a giant goblin and this happened to me.”

“Interesting….” The female scientist started to rub her fingers over the shape of Ultramom’s balls through the red spandex fabric of the mature heroine’s bikini. As the woman did this, she reached in to touch Ultramom’s cock with her other hand, running her fingers over the outline of the shaft, up and down it.

“Uuuuhh..” Ultramom gasped and her body tensed up in the negotonium restraints from the female scientist’s unwanted touching. “what are you doing to me?” The heroine asked, feeling aroused.

“I want to make you cum Ultramom” the woman smiled at the captive heroine as she stroked and fondled Ultramom’s cock and balls. Her fingers stroking the heroine’s cock and fondling the older heroine’s balls. “I want you to cum so I can study your sperm and see if it contains your powers. Cum for me Ultramom.”

“Uuuuhhh…..no…..I won’t…..you can’t do this to me…..can’t make me cum…” Ultramom threw her head back and struggled against the restraints, but the negotonium held and kept her weak. All the heroine could do was writhe as the scientist woman masterbated her. “uuuuuhhh…I…I…..won’t cum….I will resist….” Ultramom gritted her teeth and tried to resist the arousal building between her legs.

The female scientist was not about to give up though. She turned to her assistant has her hand wrapped around the shape of Ultramom’s cock and began to stroke it. Sliding up and down the shaft contained inside Ultramom’s tight bikini. “Help me. Play with Ultramom’s breasts to break down her resistance.” The assistant who was a younger woman than the scientist smiled as she walked over and behind the negotonium rack that was holding Ultramom captive.

“No please, don’t listen to her....help me” Ultramom pleaded. Her protests were useless as she felt the other woman’s hands reach around her and grab her breasts through the blue spandex of her top. Looking down Ultramom saw the woman’s hands cup her breasts and she felt them being squeezed pushed together. “Aaaaahhhhh” Ultramom closed her eyes and gritted her teeth.

“Play with her nipples.” The female scientist instructed to her assistant. She was stroking Ultramom’s hard throbbing cock and rubbing the undersides of Ultramom’s balls as her assistant rubbed her fingertips over the shape of the heroine’s nipples and around them. The scientist and her assistant were rewarded by heavier breathing and more gasps and moans from Ultramom. Feeling Ultramom’s body tense and the heroine’s balls tighten, the female scientist knew her patient was close. She pulled down the front of Ultramom’s red bikini, exposing the heroine’s throbbing cock, surrounded by a dark forest of pubic hair and reached for a cup as she resumed stroking Ultramom. “Cum for me Ultramom.” The female scientist said.

“Uuuuuhhh….n…nnn…noo” Ultramom said as she tried with all her strength not to cum.

“Cum for me Ultramom, cum.” The scientist said as she grabbed a small piece of negotonium and rubbed it against Ultramom’s cock and balls.

“Uuuuuuuuuuhhh……noooooooo……uuuuuuuuuuuuuuuuuuuuuuuuuhhhhhhhh” Ultramom threw her head back, her body tensed up and her balls pulsed as her cum shot out of her cock.

The female scientist was quick enough and managed to get the cup over Ultramom’s cock as the heroine shot her sperm into the container. She held Ultramom’s cock as it released several long shots of sperm into the cup. “That’s it Ultramom, don’t you feel better?” the woman said smiling and laughing as Ultramom’s cock began to soften. After a few more smaller shots of sperm, the female scientist released Ultramom’s cock and pulled the heroine’s bikini back up. “That wasn’t so bad was it?” The woman stood and noted that Ultramom was hanging in the restraints looking very weak and drained. Noting that, the woman motioned for her assistant to follow and left Ultramom helpless as they went to study the superheroine’s cum.
