As Jill pushed her horse cock into Dan's pussy from behind, dhe was surprised at her actions. Her intelligence gradually returning to normal, (Dan had felt bad about making her an idiot and had reversed that change) she suddenly became aware of the proportions of her dick.
Dan, for his part, was still under the influence of the increased libido change that Jill had entered a while back and had programmed a similar, albeit more intense, sexual drive into Jill. To deal with the mass of Jill's dick, Dan had made some morifications to his own body.
Jill was amazed as Dan's pussy grew to accomodate her throbbing member. Dan gasped as he felt Jill's dick plunge deeper and deeper into him. He squeezed his new pussy muscles, causing Jill to shudder with delight. Jill continued to thrust deeper and deeper, finally plunging her horse cock fully into Dan, her softball sized testicles slapping Dan's round ass. When she could no longer stand it, she loosed an orgasm more intense than wnything she had felt before, pumping buckets of come into Dan's pussy.
Pulling her dick out of Dan, Jill stared in amazement at the size of her cock. Now, back at her normal level of intelligence, she wondered why her dick was still so hard.."Uh, Dan, It is still really hard. And I am still really horny", she sttated to complain.
Dan knew what was going on. He had progeammed Jill to have a perpetual erection with a sex drive to match his.
Smiling, Dan turned and got on his knees in front of Jill, semen dripping in huge globs from his pussy onto the floor. Dan opened his mouth and thought "Let's see how she likes my new throat".
As Dan began to suck Jill's dick into his mouth, Jill realized why Dan had liked blow jobs so much - this was great. Dan opened his mouth even wider as he sucked harder and harder, slowly pushing Jill's dick deeper and deeper. He felt the cock pass through his throat and deeper (great, the anti-gag program works!). Soon Jill's balls were slapping Dan's chin as he had fully swallowed the cock.
Within minutes, Jill had again deposite huge quantities of cum into Dan's throat, which he hungrily swallowed.
As Jill once again removed her cock from Dan, she was still amazed that it was as rock hard as ever. Dan only smiled and said, "One more surprise, honey".
Dan turned around and got on all fours, his ripe ass pointing skyward. He reached back and pulled his ass cheeks apart, revealing a gaping hole. Jill knew exactly what to do and immediately plunged her cock into Dan's asshole. Dan gasped with delight as he felt the cock penetrate to it's fullest. Jill slid in and out loving the sight of the horse cock ramming her old ass. She gasped as she felt yer another orgasm approaching. Wanting to see her horse cock erupt, Jill withderw from Dan's ass and stroked her cock. Within seconds streams of cum erupted, spraying wildly across Dan's back and beyond. Gush after gush of cum spewew wildly everythere.
Jill sighed as she finally stopped. Then she looker in horror at the computer....It was covered in cum, the sticky fluid leaking into the internal components, causing a sizzling sound, followed by wisps of smoke.
In panic, Dan tried to wipe off the cum, but that just made it worse. In a moment a burst of flame appeared then the computed went dead. Dan looked at Jill and said "I think we are in trouble..."
Jill smiled and...............
