Jen sighed, this was now her life as a penis to Claire. She pulled in the tentacle which had stuck to her tailbone while sitting in class, but not amount of pulling worked. She was permanently attached to Claire now, she could even feel the blood flow from the tentacle throbbing into her body in soft but pleasant waves. Claire looked at Jen with a grin, and Jen felt a slight swelling of her breasts and a churning sound of her hips widening. Jen sighed and followed Claire's eyes towards Mrs. Smith, who was still talking. Jen shook her head at Claire, but her hips and breasts just kept growing while Claire stared at Mrs. Smith.
The teacher had at this point noticed the stare. "Claire, if you are too turned on to focus then get up here, with your penis." Claire giggled to herself and stood up, "Yes Mrs. Smith." She then walked up to the annoyed teacher, while Jen bit her lips. Her breasts had continuously grown so much with sloshing cum and were now heavy orbs almost the size of watermelons stuck on her chest. Her bra had already broke and her pants didn't fit anymore. With a hopeless sigh after being pulled in her connected tentacle she stood up and with an unintentional large sway of her fertile hips and walked to Mrs. Smith. Only her socks and shirt had survived the growth of her body, so the whole class got to see Jen's butt. "Be quick about it." Mrs. Smith commanded to Claire, who nodded and grabbed Jen. Mrs. Smith sat down on her chair and continued the lecture while spreading her legs. Claire forced Jen down on her knees and her face against Mrs. Smith, unfortunately, already damp crotch. Claire pulled down her teachers clothes and made Jen rub her face against Mrs. Smith's privates. Jen cursed to herself and looked up at Mrs. Smith. She glared at Jen and continued like she was a bad student. Jen opened her mouth to Mrs. Smith's lips, and just then with a push from Claire and a swelling of Mrs. Smith's pussy Jen's head was forced inside of Mrs. Smith. Everything was dark and wet inside of her teacher, and Jen's body felt so incredible hot. Jen could feel Claire grabbing her own hips like she was about to fuck Jen doggystyle, but she realized that she was going to use Jen like a huge strap-on against her teacher. The forced movement of Claire then began and Jen could do nothing but fuck her teacher like a giant cock. After a while like this Jen could hear a moan from outside of Mrs. Smith's pussy and just then cum forced its way through Jen's mouth and filled up Mrs. Smith.
Jen was pulled out and she coughed in her now much smaller form. She glared at Claire, who just stood there with a grin on her face. "Now get back to your desks." Said a now pregnant looking Mrs. Smith, covered in cum around her crotch, and she continued like this was normal.
