Explosive orgasms!

Ultramom was trying desperately to avoid cumming, unfortunately for her Maria was a sexual master who had pounded not only several of the colleges female teachers and students, but also some of the men as well to multiple orgasms. Angling her cock, she started aiming at Ultramom's sensitive G-spot whilst simultaneously rubbing Ultramom's clit.

"F-Fuck! Y-You're n-not g-gonna make m-me cum!"

"Oh you will, again and again and again!"

Reaching down between the heroines legs with her left hand, Maria grasped the negatonium butt-plug and started pulling it out and pushing it back in in time with both her thrusts and her rubbing of the bound and helpless heroines clit.

"Oh no, no, no!" Wailed Ultramom as she started cumming heavily, her body betraying her, unable to endure Maria's triple pronged ****. She watched on, helplessly as the pumps attached to her tits and cock started pulling her super powered milk and semen down towards the vats for safe keeping.

"Mmmm, delicious. And that's just the first of many..... In fact, by the time I'm done with you, you'll be begging me to fuck you again and again and again!"

Ultramom started shaking her head, mentally however she was struggling. Maria had already made her cum harder then anyone else had before, including her husband, ESPECIALLY her husband. Maria started laughing as she watched the conflict written all over Ultramom's face, her eyes defiant even as her body was slowly but surely starting to betray her.

"Hmmm, I don't think it'll take much, one...maybe two more orgasms and you'll be begging me to breed you!"

"N-Never! I'll never s-submit to you, UGH!"

Maria smiled evilly as she resumed thrusting, Ultramom shaking her head from side to side, desperately trying to resist what would seemingly be her fate. What didn't help the bound, powerless heroine was the fact that the vacuum pump that was attached to her cock was starting to make her semi-flaccid cock harden again.

Ultramom started whimpering as she felt the quadruple sensations starting up again, her cock ignoring her attempts to soften it. Nothing she did was working and she watched on in horror as her cock rose to its full length once again. Maria smirked before increasing her speed that she was fucking the hermaphrodite heroine, making Ultramom grunt, groan and whimper, her voice seemingly getting louder with every thrust. Ultramom was shocked as she felt her balls start drawing themselves up into her body, getting ready to release another load of super-powered baby batter into Dr Bluder's secure vats.
