With her girlfriend's transformation starting, she managed to undress quickly, as she wouldn't be able explain her destroyed clothes to her parents later. She bent and started to get bigger as a gray fur grew over her body, Her face lengthened into a muzzle as her ears got pointed and moved over her head. Her spine lengthened thanks to the tail that grew above her ass.
Soon the pained expression disappeared from his girlfriend's face, who had actually turned into a werewolf. She then stood up and faced you, which allowed you to see the full dimension of her transformation. In addition to turning into a werewolf your girlfriend had grown up and was now much taller than you, being at least 8 feet tall now. Another thing that caught her attention was between her legs, as since she was no longer bent over a lupine cock could be clearly seen there, which was rock hard.
You would continue by her side as you had promised, but you felt uncomfortable thinking she had become fully male, however you were relieved to realize that she had no balls, and her pussy was easily visible below the base of her member. You were embarrassed that you thought your girlfriend had fully become a male, even though each of her breasts was now as big as your head.
Without saying anything, your girlfriend advanced on you, grabbed your arms and stared at you for a few seconds, with the height difference helping the tip of her 13 inch cock to drip precum right in front of your face. She then, now much stronger than you, force you to lie face down on her bed, holding you in place with one hand and, despite your complaints, she takes off your pants, followed by your underwear, with the other. She held you tight in place and you felt the tip of her cock against your ass she was going to rape you and you couldn't do anything about it but just as she was about to finally push her cock inside you she stopped , released you and sat on the bed, putting her hands on her head.
"I'm really sorry, I didn't want to do this." your girlfriend said
You didn't know what to say and just looked at your girlfriend a little confused, taken aback by her big change in behavior, but relieved that she stopped what she was going to do to you.
"I'm so sorry, please forgive me. I thought I had gotten used to it enough and could control myself more easily this time. Every time I transform I get one hell of a boner and practically lose control of myself and act out of pure instinct to mate or, not having a partner, relieve myself on my own. I can control myself well already and I thought it would be safe to change in your presence. Seeing someone other than me here after I changed triggered my instinct to mate with an intensity I'd never felt before and I barely managed to regain control of my actions, so I ended up hurting you." your girlfriend said in response to your silence
You could see tears running down her wolf face, that's why you hugged her saying "It's okay, I was just surprised. At least you managed to get yourself under control in time."
"It's not okay at all. I may be in control right now, but I still feel a very strong urge to have sex with you." she said, her dick still hard, throbbing and dripping precum.
"But you are stronger than this desire. You no longer need to endure your condition alone, I'll give you all the support you need, except let you fuck me. With your size you would kill me." you said
"No, you better not stay here. Go away and leave me alone, I don't want to risk losing control again and ending up hurting you." your girlfriend said
