Your dick is bigger, but also other things

You see her operating her phone again at an absurd speed, then it rings.

The first thing you notice is the incredible pressure on your groin as your dick shoots up and grows to legendary porn-star size. Your hands grab at it, while you can already feel your balls have also become at least the size of large chicken eggs. Several moans and grunts involuntarily escape your lips as you pump your massive prick in lust.

"Stop jacking off you perv." she says with a sneer just as you were about to cum, "I know I'm hot, but you are my property now. You will stay horny, but only I decide when you are allowed to climax."
Your hands drop to your sides, but your dick stands as proud as it did before. If anything, the denial and her commands are making it harder.

"H-How? Why?" you manage to express between lustful moans.
The answer is as clear as it is a mystery to you. "Because I own you now. I already said that, didn't I? You have the honor of becoming my very first pleasure ****." she explains and continues, "But maybe that change was not... **** enough to make you know your place. Well, I want to experiment more anyways."

Again you see her working her phone and again there is a strange ringing sound, but this time you buckle over as soon as you heard it.

Pain, followed by an incredible heat radiated from your stomach down. Once the pain was gone you also notice the pressure on your chest as your pecs seem to balloon out. Soon they are not pecs anymore but sizable tits still smaller than those on Jess. These two additions distract you for a moment as you feel the cold air caressing your nipples like it never did before. Somewhere along the change you must also have lost all your attire, but you didn't even notice until now.

Jess looked at you with a mischievous smile, watching your face switch between terror, fear and incredible lust. You are still on your knees with your hands on the floor before you, panting as her mere presence is arousing you like nothing ever has before.

It took a moment you spend panting on all fours until you realized what else had changed. Eventually it clicked as a trickle of fluid ran down your enlarged balls making them sticky and feel cold in the air. "You... you didn't." you groan.

"No, no I did." she says as her smile turns into a wicked grin. She moves behind you and you can feel her run a finger along what used to be just your taint, but has been turned into a sopping wet cunt.

"What shall we do next, my plaything?"
