Zhorian science allows people to remain young and -- usually -- healthy for centuries, and to take on the body of any other by use of serums. Ruk's Se...um was an adaptation of this process. It was created by a bio-chemical genius whose paymistress and director was the slaver Vanora. Legend says that Vanora was miffed at the idea that it was always women who got the brand and a good switching and it was men who had all the fun. Inspired by the body-changing serums she sought out the best man. Hee-hee-heee!"I blushed three shades of crimson under her hilarity as the two lesbiansclamored for answers about me. Elise started to speak, then paused,"Girls, would you excuse us for a minute?" Seeing them obviously putout, she assured, "Just for a second, really, then I'll tell youeverything!". Reluctantly., the two of them withdrew and she turned tome."Well, Miss-ter Crayle," she teased, "you seem to be quite the Master ofDisguise... or is it Mistress?" Very funny!" I fumed, covering myself. As me and Zhedd kissed, I noticed Emmanuel had stopped fondling my sister's breast. He had his hand up the front of my sister's black mini skirt and was rubbing crouch of her little pair of shiny white satin bikini panties. Emmanuel, kept trying to kiss my sister on the mouth, but she kept turning away.I moved my hand up placing it in the middle of his chest and gently pushing him back breaking our kiss. While with my left hand, I pushed Zhedd's hand out from under my skirt and said to him. He watched as the tip of his cock kept coming out from between Mrs. Bentley’s big breasts only to disappear again within their mass. He tit-fucked his teacher while she slept, squeezing the tits he was holding. Then he felt it… his orgasm approaching. The first spurt hit Mrs. Bentley on the chin and neck, leaving a trail to her breasts. Then another erupted. Peter released his hold on his teacher’s breasts and began stroking his cock. The next spurt of sperm flew all the way.
