As you watched your girlfriend her face faded leaving just a smooth surface of skin in place and her hair was totally absorbed back to her head. What was left of the head thinned to just a cylindrical tube of flesh about the same thickness as her neck, from which an opening appeared at the end and the skin retracted, revealing a small red mushroom-shaped head. You soon recognized that her head had turned into a cock, but for some reason you didn't even know why, you knew was weird but you couldn't think of it as wrong or feel disgusted. Soon you saw her breasts grow from B-Cup to E-cup stretching her blouse.
"Tell me, what do you think of my new body?" your girlfriend asked, you noticed her voice coming from underneath.
"I don't know what to say, it's weird. And how are you managing to speak?" you said
"It's easy, check it out." your girlfriend said and unbuttoned her skirt, letting it fall to the floor. You could see a familiar but totally out of place shape in her panties, which left you no doubt by the eyes that were watching you just above the edges of the fabric. She then took off her underwear and showed the entirety of her face that was now in her crotch, where her vagina had disappeared without a trace.
"Wow, in this one you excelled. Why did you choose such a bizarre transformation?" you said
"Well... it's just... Okay, but don't laugh. I've always had a crush on freaks and, you know, since you gave me the chance I decided to take the opportunity to become a freak." your girlfriend said
"I understand but, why a cock between your shoulders?" you asked
"It's because I want to know what a male orgasm is like. You won't be mad at me for this will you?" she said
You could understand what she meant and you knew you couldn't be mad at her because you had given her the freedom to choose whatever transformation she wanted, so you couldn't blame her for choosing to have a dick. Looking closer you thought she was even sexier now and felt your cock get hard.
"Ho ho ho, I see my new body turned you on, isn't that your naughty guy?" your girlfriend said and hugged you. Having her face down there now she unzipped your pants and unbuttoned them with her mouth, the same one she used to pull down your underwear and suck your cock.
In this different blowjob you saw your girlfriend's dick get hard, there was 10 inches of manhood between her shoulders, the tip of which she rubbed in your face. You then started stroking her cock with one hand and with the other grabbed one of her breasts. You felt right then that her bra was wet.
Your girlfriend stopped sucking your cock and said "This is the last little surprise I left for you." then she took off her blouse and bra revealing that she had a pussy on each breast with her nipples serving as her clits.
"You are just amazing." You said, completely stripped off your clothes and rejoined your girlfriend, who resumed her blowjob.
This time you guided her cock to your mouth and started sucking, then with your hands placed your fingers in her pussies. You wanted to test the limits by putting one more finger at a time, until there came a point where your whole hands had gone in, you had your hands inside your girlfriend's breasts.
All the stimulation was too much for his girlfriend who ended up coming. You felt her cock throbbing and knowing the arrival of her orgasm took your mouth off the male member just as one jet of cum after another started to shoot from the tip of the member in front of your face. Her pussy also tightened around your hands soon making you cum too.
"That... was... really... intense." your girlfriend said after sitting up panting after her orgasm.
"I'm seeing how much you liked it, I've never seen so much cum ejaculated from a single cock." you said
"You're surprised yeah, so wait and see what comes next. Since now it's my turn answer me, Transform or Dare?" your girlfriend said
