Wait... breed? Before Jeff could answer, her mother approached. She grabbed the dog's collar and gently tugged.
"Come on, Luke. You know you have to share," she said, not waiting for an answer from Jeff.
Luke's knot pulled at the entrance of Jeff's new pussy, the pressure causing another spurt of cum to coat her insides. Jeff couldn't help but let out a small moan in front of her mother at the stretching sensation from Luke's swollen knot tugging at her new canine cunt. This felt different from having a human vagina. The entrance to her canine pussy was biologically designed to contract and keep dog cock locked inside her for the duration of the mating period. A new realization that her body was now only suitable for sex with dogs washed over her and added to the mixture of shame, embarrassment and arousal she was feeling as her mother nonchalantly watched her fuck her pet.
After a few moments, Luke's knot finally deflated enough to slip free and a gob of dog cum dribbled to the floor.
"You better hope he hasn't knocked you up again, young lady. Mr. Jones is willing to pay a small fortune if you can foster a litter of his pups. Come on up, Mr. Jones!"
"Wait! Don't I get a say in this?" Jeff finally managed to muster.
"Oh, don't be shy, sweetie! You'll do great! You always do!"
Before Jeff could say anything else, a man and his large dog appeared in the doorway. He looked down at Jeff and the eyes of a stranger suddenly made her hyper aware of her body. Six teats with plump nipples hung beneath her as she stood on four dog legs, her dog pussy exposed and still drooling Luke's cum. A wave of embarrassment washed over her again and Jeff looked away, focusing her attention instead on the large dog at the man's side. His red doggy cock had already started to peek out from his sheath. This was not the idyllic future with Luke that Jeff had in mind!
"Ah, so this is your daughter." Mr. Jones entered the room and began to inspect Jeff like a show dog. He put his hands on her hips, ass, tail, even cupping one of her teats in his hand and looking at her pussy before leaning back in apparent approval. Jeff looked up at her mother who only smiled back passively as if this were routine. Jeff's face grew hot from the humiliation of being handled like a breeding bitch.
"Yes, she looks quite healthy. I think this will work just fine. Come, Champ!"
The enormous dog, apparently named Champ, dutifully trotted toward his owner while eyeing Jeff. His cock had made its way even further out of his sheath, aroused by the musk of sex still in the air from Jeff and Luke's last romp. Luke growled and lunged forward. For a split second, Jeff felt like a damsel in distress who's knight in shining armor had come to save her. But this fantasy was abruptly cut short as Jeff's mother caught hold of Luke's collar and scolded him. Luke quickly relented with an obedient whine as he watched his mate's rear end get sniffed by the larger male. Jeff let out a surprised yelp as Champ began to lick her pussy clean.
