-Hey, I can swear I can do jig whole day long! - Mary exclaimed and stomped playfully.
-You sure can. But what about a funnier thing to do, my hot ginger dancer? - asked Travis playfully and put his hand on Mary's waist.
-Not so fast, lad. - Mary replied with a thick accent, which she could act or the vial was taking more effect on her. - I think you should taste some of these too.
-Alright. Maybe one with muscles....or make little Travis bigger, if you want of course.
-Not so fast, my dear. I pick one for me and now I pick one for you.
-Blindly?
-Of course. Did you really expect to choose one after your trick?
-Fair enough.
-Don't be afraid, you will like it. - and Mary gave Travis his most insidious smile.
-I hope so. - Travis exhaled and closed his eyes - Go on, babe, I trust you.
-Let's see.
Mary scanned the box with vials and found a female vial. The plan has born in her mind immediately, she'll pay Travis the same coin as he did for her. It would be fair...and fun. Mary carefully mixed Irish and female vials and gave it to Travis.
-What is it, Mary?
-You'll see. Now, stop talking and bottoms up!
Mary forced Travis to drink the vial, so the boyfriend did so not to spill the vial's potion.
-That was sweet.
-Oh, shut up already...
And Mary covered Travis' lips with hers in a passionate kiss. All this transformation and body morphing stuff has turned her. Just a little but still. Travis did not expect such enthusiasm from Mary:
-Wow, hon, are you sure you didn't drink anything else, like, aphrodisiac.
-I am sure we don't need one.
And then Mary started to strip Travis quickly. Her boyfriend did not hesitate also and helped Mary to get rid of her clothes. Mary covered Travis' body with kisses, noticing how it was slowly changing and overwhelming Travis with pleasure to mask the transformation. They were having fun after all.
Mary slide down to the Travis' groin and started to stroke his dick and then swallowed it entirely
-Oh, jeez, Mary, you are the best - moaned Travis, completely dissolving in the ecstatic feeling, without noticing how his hair grew longer by inch in a second.
Travis gave the massive and hot load but Mary did not stop even for a second. She felt like Travis' cock was shrinking into him and Mary accompanied this sensitive journey.
-Oh, oh, God. Mary...What the..?! - Travis's voice became higher with each word. He felt like his face was reshaping and readjusting its features, making him someone else. However, Travis could not concentrate longer because a new wave of alien and overwhelming pleasure rushed over him.
Mary ended up with Travis's cock but now a nice and firm slit formed between Travis's legs and Mary ate it with passion, squeezing moans and sighs from Travis. He felt like he was becoming taller, how his legs gained tight and strong muscles. Instinctively, he placed his hands on his chest to feel like two soft bumps were forming on it. Travis pinched his nipples to feel them become more sensitive. He stopped to analyze, to think over what was happening and just went with the flow. After a few more endearments from Mary and shifting feelings within, Travis reached his first female orgasm, which exploded within him with a power of thousand fireworks.
Tired, and heavy breathing, Travis and Mary slid down on the floor.
-Well, that was unusual, I must admit - said Travis with his new soft voice.
-You don't say. - answered Mary
