She makes you transform

Gemma stands up in front of you, with one hand resting against your cheek. She pulls the dressing gowns cord free, allowing her cotton robe to fall open at the front. As you suspected, she's wearing nothing beneath. Her perky little breasts bounce slightly, her long nipples already stiff. She rubs at her dark pussylips, slipping a finger inside herself to draw out her juices. Her fingers smear her shaved mons with moisture making the dark flesh gleam. Your cock is uncomfortably hard in your pants not and you fidget slightly on the bed.

"Unzip yourself and pull your cock out." Gemma commands you. "Before I allow you to transform I want a taste of your dick."

You do as you are told, letting the cock spring up out of your unzipped fly. Gemma takes hold and kneels, rubbing her cheek against the hot flesh. She opens her mouth and takes the cock's tip in her mouth, sucking on the plum like head as if it was a popsicle. When you begin to moan with arousal she looks up, her lips still tight and hot around your cock. She gives it another couple of hard sucks then lifts her head from your tool.

"Like that don't you?" She teases. "But I don't want you blowing your load right now. Now it's time for you to transform."

Gemma steps away from you, leaving you sexually excited and out of contact with her. You change before her eyes.

"Hello again Doe." Gemma says, admiring you.

The horniness you were feeling moments before with Gemma's mouth on your cock seems to have carried over during the change. Your pussy is aching to be touched and your big breasts are squashed inside a shirt that's now far too tight.

"Get those clothes off." You're ordered. "I can see that I'll need to give you an orgasm or two to allow you to think straight."

You readily obey, peeling the jeans off your slim legs and struggling out of the overstretched T-shirt. Gemma reaches out and lifts one of your massive tits, feeling the weight and firmness of it. She squeezes and pulls at the hardening nipple, making it swell. Unlike her dark nipples, your's are a rosy pink. Not as long maybe, but fatter than your mistress's. Gemma leans forward and suckles on the teat, nibbling it gently. She switches breasts and repeats until both nipples are stiffly swollen.

"I love your boobs." Gemma says. "So much bigger than my own handfuls and your cherry pink nipples are so sweet."

Gemma pinches a nipple with each hand to emphasise her words. Her fingers pinch hard making you wince and a little squeal escapes your lips. Your mistress silences this by kissing you hard, you return the kiss eagerly moving your focus from the twin pinpoints of pain in your chest.

"Good girl." Gemma says approvingly. "You didn't pull back or try to push my hands away from your nipples. I thought I'd need to teach you this, but you transferred the sensation of pain to sexual arousal naturally. I think you were born to be submissive."

"Now lay back and spead those beautiful legs." Gemma says. "There'll be a little more pain, but more pleasure. An orgasm will dull your arousal a little and we can get dressed and visit the admin office."

You lie back, lifting your knees and spreading your thighs to expose the coral coloured lips of your pussy with it's sparse bush of light blonde hair.
