Mitch's eyes go wide as he observes your breasts blossom and your face grow more feminine by the second. Your penis has already shrunken back inside your vagina... and you love the feeling of it!
You get up from the couch and slowly start to undress, for the canine bitch you are on the inside commands you to get rid of these unpleasant and tight clothes.
Butch positions himself between you and Mitch, who still sits on the couch, breathing hard.
"Very well," he growls, "lets get this human have a taste what being my bitch is all about..."
Suddenly Mitch starts to moan and whimper, his head gets thrown back and his arms flail slightly. He shivers and seems to be experiencing multiple orgasms over and over again.
Feminine breasts start to blossom on his formerly manly chest and his scent changes in unison with his gender.
"Undress your new pack mate," Butch commands you, "I want her to experience her first transformation now, so I can mount her to make her mine!"
You feel yourself unable to resist your master Butch's command, so you start to rip Mitch's clothes from his still shaking body.
He's developed very nice breasts and his vaginas' scent is intoxicating. You slightly start to drool and you feel your own vagina get wet with sexual excitement.
Slight fur starts sprouting all over your body as you smell Butch's dominant-manly scent. You're getting into a canine bitch's heat again!
"Whats happeningrrrr to meee..." Mitch whines in a feminine pitch as Butch steps closer to his newest subordinate.
Soon Mitch's naked (up to the collar that is still 'round her neck) and her whole body glows of the bitch's heat the collar infuses her with.
"Now, my bitch," Butch growls, "shed your human skin and become what you already are on the inside. Become my bitch!"
