She tries to fight but fails!

Steeling herself mentally as best she could, Ultramom tries desperately not to cum again at Maria's hands, cock, etc. Physically she was on the brink on defeat, but she felt that if she could hold onto her mental faculties she felt like she would have a chance at surviving this, she had activated her tracking beacon as soon as she entered Maria's office just in case.

"Ah, I see what you're doing." Said Maria as she continued to thrust her cock into Ultramom's wet cunt. "You're thinking that the tracking device in your costume will let your partner Ultraboy know where you are so that he can come and save the day. Unfortunately this office (courtesy of Dr Bluder) has been fitted with the very latest jamming technology. Sorry!"

Ultramom's face fell as she realized that her only real hope of escaping had just gone up in smoke, she also realized that Maria was right, without any kind of escape plan she would be broken. Ultramom tried to think of something, ANYTHING, that could save her.

Maria smiled at the confused look on her preys face and knew that just one last thing would break her cocksleeves mind. Taking her right hand off of Ultramom's throbbing clit, Maria reached down under her desk and pulled out the item she'd been looking for, a Hitachi wand!

"N-NO! D-don't you DARE!"

"Oh I DARE!"

Maria flicked the switch and placed the wand onto Ultramom's defenseless clit.

"AAAAGGGGHHHH!!!!"

Maria laughed evilly as Ultramom lost what little control she had over her body, her cock belched out another heavy load into the vacuum pump. Her breasts leaking milk like a sieve.

"Give up yet hero?"

"N-no-AAAAGGGGHHHH!!M-Make it s-stop! UUUUGGGGHHHH!"

"Not until you beg me to inseminate you!"

"N-Nev.......N-Nev.......N-N........NUT IN ME! BREED ME!"

"Mmmmm, as you wish! By the way I've got about a months worth ready to get the job done!"

After turning off the Hitachi, Maria started hammering away at Ultramom's defenseless pussy, just kissing the hermaphrodites cervix. After a couple more deep thrusts, Maria buried her cock deep and flooded her preys womb.
