Long....

Dr Bluder moaned as she started bouncing harder on the prone Ultraboy's cock, her breathing starting to get heavy as her first orgasm started to creep up on her. She squealed and shook as it hit her, her pussy tightening on Ultraboy, trying to get him to cum inside her, but having not long ago bred his own mother, the young man was nowhere near his climax.

Dr Bluder was enjoying herself, one of her biggest enemies had been taken to her cell, her womb full of her son's potent cum, the son who was underneath her, her one job for him to be her breeder. Motioning to one of her slaves, Dr Bluder got him to get an experimental **** that the evil doctor had been trialling on some unfortunate victims. Her experiments had obviously had many failures which she took on board and made the necessary adjustments, making this final version.

"Ultraboy, I'm going to give you another ****, one that will make your cum extra potent, giving it a 1000% success rate!" Dr Bluder took the syringe from her **** and injected it into Ultraboy's bound arm, the **** easily getting into Ultraboy's testes
