Jennifer slowly walks towards Mo, her pussy getting wetter by the second. Mo can smell something different about his, owner and goes to sniff her pussy. To Mo, it smells like it's just waiting to be bred with. Mo licks her pussy once, and this sends a wave of pleasure over Jennifer. She's confused as to why something like this is making her feel so good. Jennifer can't resist and sits down on the ground with her legs spread out and pats her pussy, signaling Mo to come over. Mo eagerly runs over to Jennifer and starts licking her pussy as if he was drinking water from a bowl for the first time in days.
Jennifer was in heaven and was moaning loudly, encouraging Mo. After a while, Jennifer wanted more of Mo and looked down at Mo's crotch and saw the biggest cock she had ever seen in her life. Seeing Mo's still-growing cock turned Jennifer on and she couldn't help herself. She ripped off all of her clothes got down on her hands and knees and slapped her ass, inviting Mo to take advantage of her and pound her as hard as he wanted. Mo rushed over to her gladly and placed his front paws on her back, and began thrusting his huge cock in Jennifer's direction. Eventually, Mo found Jennifer's soaked pussy and thrust his cock as hard as he could into it. Jeniffer screamed, practically a howl, it felt so good.
Mo continued punding Jennifer as hard as he could, and each time Jennifer screamed with pleasure, she was a bitch in heat. Jennifer loved the feeling of Mo's fat dick smashing against her womb, almost penetrating it. Mo loved his new bitch, how her tight pussy closed around his cock and squeezed it. Mo then finally penetrated Jennifer's womb, causing her to let out yet another loud scream, and at the same time knotted Jennifer. Jennifer loved the feeling of his knot insider of her, it felt amazing. Then, Mo suddenly let out his huge seed inside of Jennifer, filling her to the brim, not a single drop escaped her pussy. Jennifer felt like she was going to lose her mind, the sensation of Mo's hot cum filling her up felt amazing.
Jen wanted Mo's giant cock to stay inside of her forever, she never wanted it to leave her. Jennifer turned her body around to face Mo and wrapped her legs and arms around him. Jen and Mo stayed in that position for at least 30 minutes, Jennifer just enjoying the feeling of dog semen swimming around inside of her as Mo's cock stayed locked in place inside of her pussy. Then Jen heard a bark coming from outside the door. Immediately Mo unlatched himself from Jennifer and began barking too. Jennifer felt a sharp pain as Mo's enormous knot along with his massive cock was torn out from her tight pussy. A waterfall of cum and pussy juice flowed out of Jennifer. Jen looked at Mo as he left Jennifer and looked at his cock. It was much bigger than when she first saw it.
(That huge thing was inside of me?!) Jennifer thought to herself, perplexed. Mo then ran away to the door.
Jennifer eventually went to the door as well and opened it, then saw a large seemingly stray black Great Dane. Jen looked down at the Great Dane's crotch and saw it too had an enormous erection like Mo's, except this dog's dick was much bigger than Mo's. It looked to be about 3 times the size of Mo's. Upon the Great Dane seeing Jennifer, it began thrusting its hips as if it were fucking something. That was when Jennifer realized that this dog was looking to mate with Jennifer. Jeniffer got instantly wet at the thought of Mo shoving his huge cock down her throat as this Great Dane shoved his even bigger dick into her pussy and planting its seed presumably large seed in her.
Jennifer decided to let the stray in and before Jennifer could even close the door the stray pounced on Jennifer's body and began savagely fucking Jen's tight pussy with its enormous cock as Jennifer laid on all fours. The pleasure Jen got from this was even greater than the pleasure Mo gave her and sure enough, the scream was even greater as well. This stray's dick easily penetrated Jennifer's womb as well and was moving its knot in and out of Jeniffer as well. Jennifer was once again a bitch in heat and she loved it. Mo watched as this stray was savagely fucking who was supposed to be his bitch, and realized that this stray was, in fact, the alpha here and that Jennifer was this stray's bitch.
Mo remembered that there was another hole Jennifer used whenever she screamed and decided to try putting his dick in there and seeing how it felt. Mo went to face Jennifer and Jen saw that Mo's dick was just as large as before and was glad to see it that way. Jennifer opened her mouth wide and allowed Mo to shove his cock down her throat. The feeling of Jennifer gagging made Mo's cock feel even better and made him happy that Jennifer had more than just one pleasurable hole. Jennifer felt the best she has ever felt in her entire life as both her pussy and her mouth were having enormous cocks shoved down them. Then, at the same exact time, both the stray and Mo came inside of Jennifer. Jen gleefully swallowed every last drop of Mo's hot delicious cum and gladly accepted the stray's warm cum into her womb.
Both the stray and Mo were now firmly knotted inside of Jennifer, so Jen made sure that Mo's dick didn't leave her mouth and that this stray's cock didn't leave her pussy. Eventually, both of their cocks slowly shrank and they were able to easily take their dicks out of Jennifer. A waterfall on dog cum flowing out of Jennifer as the stray pulled out of her.
Jen then decided that she would name the stray, and decided on the name Shadow after his dark fur.
Later that night, when Jen was watching television, Mo and Shadow came up to her and were clearly begging for more sex. "Ok," Jennifer said to them, "but we'll need to do it quick before my roommate gets home." Jen then gets down on all fours and presents herself eagerly to both of them. As Mo begins to move toward her face, Shadow barks and calls him over, gesturing to her pussy and her ass. Mo understands and lays on his back underneath Jennifer and stick his dick inside of her vagina as he licks Jennifer's face gleefully. Shadow then gets on top of Jennifer and sticks his dick into her asshole and begins fucking her vigorously with no restraint. Jennifer moans loudly and screams as her ass and pussy are being pounded by two dogs.
Not after long, Shadow begins going at Jennifer even faster and harder than before, practically destroying her ass. Jennifer, a bitch in heat, lets out another loud scream followed by her words.
"I'M YOUR BITCH, SHADOW! YOU CAN FUCK ME WHENEVER YOU WANT! MY BODY IS YOURS AND YOU MAY DO AS YOU PLEASE WITH IT. PLEASE FILL MY HOLES AND CUM IN MY DEEPEST PARTS!"
Shadow is glad to know that his bitch has accepted him and will submit to him whenever he wants. Jennifer begins kissing Mo and kissing him with tongue. Soon Mo and Jennifer are intensely making out as Shadow and Mo pound her holes as hard and as fast as possible, and then they both cum deep inside of her. As Jennifer lays there, a bitch in heat, she looks at the clock and realizes that her roommate Pat will be home any minute. Jennifer gets up and luckily isn't knotted and rushes to her room, Mo and Shadow following. Mo and Shadow clearly want to continue and complete destroy Jennifer's holes, so Shadow forces his bitch, Jennifer, to continue having sex with them.
