Not quite the reaction that Adam expected

Adam moved in closer towards Christine, slowly, step by step.
Smirking, confident.
Without regard to his state of undress in broad daylight.
Above any doubts in his knowledge, that his enormous boner was enticing and alluring enough to get him anything he wanted.
That Christine would fall to her knees and start to worship his cock, just like the girls in the porn videos and advertisements. Just like Devon and Clark in the shower.

He didn't realize, he didn't see, that Christine's hand was in fact not reaching towards his enthralling cock.
That it reached inside her purse, and reappeared with a taser for self defense.
And Christine did not hesitate to use it.

When he was in arms-distance of Christine, the jolt hit Adam in the chest. He felt his body stiffen, quickly losing all motor skills. He felt the electricity surge through his chest, causing havoc.
And at the same time that jolt put him over the edge. His aching and throbbing cock erupted like a fountain, spewing spurt after spurt, splash after splash, as his enormous shaft jerked without restrictions in all directions.
Most of his cum did indeed hit the girl holding the taser to his chest, and he could see how she soon was drenched and painted white, her top, her glasses, her face, her hair. And that was the last image in Adam's mind. The electric charge, the strain on his body by his massive ejaculation, and the "Growth X" pills working in his body - all this together was enough to make him pass out.
