Drake opened the bottle & drink half the liquid in it. Drake put the bottle on the table & cooed as his body slimmed some & his slit moved more toward the underside of his tail. Adam immediately could smell that Drake's scent had changed. Drake now in a female voice spoke "Come on get naked. I got only 100 hours as a female & I want to fuck." Drake was impatient. Adam stood up & stripped completely naked now being totally naked like Drake was. Adam looked over the now female lizard & said "We aren't quite right for sex yet." Drake very confused by his former human now lizard statement asked "What you mean?" "We too evolved for sex." Adam hinted with a grin. The now female lizard was confused at first intill the words 'Too evolved' sunk in. Drake's tail twitched excited as she nearly yelled "I can fix that." Drake quickly jumped up & left the room. She returned a few minutes later with an odd looking red plastic looking skull of an unknown animal. "What's that?" Adam asked curious. "An evo skull. Whoever is looking at it can with a thought will the skull to evolve or devolve them." Drake again answered like a scientist. Drake placed it on the table too. "That simple?" Adam asked & Drake nodded. "Let's do it." Drake the impatient female lizard said. The 2 anthro lizards looked right at the skull & stated aloud their desires "Devolve." The skull lit up real quick & bathed them in a red light. The light then disappeared as the skull went back to normal. Both lizards could feel the sensation of things happening inside of their bodies. Drake was the first to notice his hands were changing & she looked at them. "My God! You're devolving!" Adam yelled shocked. Drake gave a toothy smile "So are you."
