Jen started walking toward school, the breeze on her bare legs and ass making her completely aware of her current state of dress. She had almost made it to school when she heard a bark. She turned and saw to her horror a doberman, she tried to stop herself as she walked over to the dog and dropped her bag. Jen couldn't stop herself as she grabbed the hind quarters of the dog, pressing her crotch to its rear. She began humping, her movements rhythmic and slow at first and beginning to quicken.
"Ahhhh..." Jen moaned as she continued her movements, the dog confused struggled against her, but found it couldn't get away, that she seemed stuck, the flesh on her hind quarters had already fused with Jen's body, and Jen could feel everything, her every movement and struggle felt as if someone where manipulating her clit. The dog's features began to change, it's legs melting into Jen's, leaving a patch of fur on Jen's thighs, her belly bloated, the dog struggled to pull away as she felt her new master's body and lust. The commotion had drawn the attention of the dog's owner who ran out of her house.
"WHAT ARE YOU DOING TO MY DOG???" She screamed in horror, as the dog's head began to shift to a long point, it whimpered and howled in fear, the woman screaming at the site grabbing at the newly forming cock head, "JACQUIE!!!! JACQUIE!!! NO!!!!" She cried and yelled. Jacquie's paws scrabbled in the grass, struggling with all their might, until they started melting away, merging into the dog's body, her body bloated, her stomach, deforming into not only a pair of enormous balls, but the sheath of Jen's new cock, the woman backed away in horror as the fur and flesh of her dog changed bloating into a massive dog cock, it's sides bloating out into a large knot. Jen fell backwards on her ass, her new hundred pound cock standing straight in the air, Jen moaned in hunger, shacking and sweating. Jacquies owner rushed over to Jen, grabbing her by the throat.
"BRING JACQUIE BACK YOU FUCKING MONSTER, I'LL......" The woman's eyes glazed over and she let go of Jen, she stared at her and then looked at the poor girl's massive cock, standing a massive three feet up in the air, her balls the size of cantaloupes, the owner of the cock moaning and shacking.
"Miss.." the woman started "...are you okay, do you need some help with... um..."
"P...Please...." Jen moaned, the woman, somewhat reluctant that she asked began rubbing Jen's new cock, Jen moaned, loudly trying to tell her to stop, but she couldn't get the words out, as the woman quickly brought Jen do climax, her new cock spewing seed into the air and onto the lawn in front of her. Jen still shaking slowly sat up after a few minutes, her new cock slowly growing soft and retracting into her new sheath.
"I'm sorry..." Jen sighed.
"Oh, no it's alright, I deal with this all the time. Usually with dogs though, and never with a cock this big. Are you okay, have you gone into heat or...." Jen stared at her for a minute, and found her mouth moving with her making any effort. "Oh no, I don't go into heat, I've got a human sex drive and all."
"Oh you poor thing, that.. beast..." the woman blushed at the thought "... must give you a lot of trouble."
"Oh it does, but it's easy enough to tame, it just hit me hard this morning." Jen said as she got up, not under her own control, and grabbed her bag. "Thanks for the help ma'am." Jen started off to school as the woman returned to her house, unsure of why she felt scared and angry. Jen stopped a few feet away out of view, and choked back a sob as she looked down at the monster now attached to her, it's head poking out slightly after it's first action, she felt the new weight on her body, and tried to decided whether to trek home or go to school.
