Professor Ami and Doctor Nyxon have concocted a formula with a caffeine content much higher than coffee but without the annoying jitters and heart palpitations. Just pure energy! Being dedicated scientists, of course they want to sample the elixir themselves. After taking a hearty swig they wait for the effects. Ami reaches for her journal to take notes and in doing so exposes her round behind to Nyxon, who is immediately intrigued. She can't help but reach over and grab it. Ami is shocked, but she does enjoy the attention. Soon Nyxon is groping all over Ami's ample bottom, and she suddenly feels compelled to start humping it. She grinds and bumps her hips against Ami's ass with uncontrollable desire. Neither scientist knows how these sudden urges came about, but they don't deny them. They just continue to enjoy it. They take turns humping each other's asses. Their thrusts getting more intense by the second. Finally they both erupt into orgasm together, and collapse on the couch. They take a moment to collect themselves, and Ami wonders briefly if the elixir they consumed might have something to do with their erratic behavior. Nyxon dismisses this idea and takes another sip, and Ami follows suit. After all of the excitement they could both use a little energy boost!
