He calls David, "Hey Dave you busy mate? If your not busy, Ive got something here i wanna show you,"
"I will be right over" dave replies.
As Mark Waited for Dave to arrive he was curious as to what vial he should use, as he was searching he came accross a vial which had a pink liquid in. Mark looked at the vial to see if it had a labal on, but he couldnt see one, he took the stopper out the top of the vial and was about to swallow the liquid when the doorbell rang.
Mark Put the stopper back in and went down to let dave in. They both went straight back up to marks room. "So what you got to show me then?"
"These Vials, they can transformation potions, I got them online and i want to see if they work but i need someone here incase something goes wrong and i need you to change me back,"
"And how do i do that"
"you use this vial here, it will return me back to myself,"
Mark handed dave a vial with clear liquid in, mark then stripped down to his boxers and looked in the case for a vial to try, Mark picked up the vial with the pink liquid in and knecked it.
The liquid tasted of Strawberries and cream to marks surprise. Mark walked over to the mirror to watch the changes happen, At first nothing happened,then he noticed his hair started to change colour, from brown to blond as it grew further down his neck to his shoulders, all his body hair fell out as his face started to get smaller, his cheeks became more rounded and femine in appearance, his nose to became femine, his lips started to get fuller and more pouty, thee changes started to speed up now has his arms became thinner and his hands become smaller as his finger nails grow, his feet become smaller and more femine, his legs become more shapely as fat distribute on them, marks waist starts to shink as his hips start to widen, his ass to starts to get bigger and rounder, his chest starts to feel weird as nipples start to swell bigger and bigger in till they stopped at a D cup, the final changes were starting to happen now as his dick started to shrink smaller and smaller in till it went inside dragging his ball sack with it, marks changes finaly stopped he looked in the mirror he saw the most beautiful girl he has ever seen, mark pulled down her boxers to reveal a clean shaven pussy.
Suddenly Dave was behind mark, Dave was naked and his cock was hard, mark bent down and put it in his mouth, mark didnt understand why he did this but it just felt good to do, he kept sucking in till Dave shot his load in marks mouth, dave then picked mark up and laid her on the bed, dave went down to marks pussy and starte licking, mark had never felt anything like this before, Mark moaned in ecstasy as pleasure ran through her body, then dave got his cock and slowly placed it in mark, Mark moaned louder as the pleasure made him want more, dave went slow at first but picked up pace, each time marks moans were getting louder and louder in till
