(Another Male on Futa and Futa on male sex scene. Skip if you don't want to read it, you won't miss any plot....Also, since it a beastkin, there is some animal part. No real animal is involved....you get what I mean.)

Soul Pledge. A very important ritual for a Beastkin. By offering their body and Soul to their Master, it is to show him/her that they would never betray and they would follow their Master, even to the death. And if the Master did not release the Soul Pledge of a Beastkin before drawing his/her last breath. That beast will die with him/her. And that what you read in the book about the beastkin.

"Kagaya…..you don't need to force yourse-."

"Please!.....don't push me away...… I'm prepared." (Kaguya) She slowly walks toward the bed and sits on your bed.

Then you enter into deep thought. ("Is it ok for me to do this? I mean, we just met for two days.") you glace at her, and she also avoids your eyes. ("Oh my god, she is so hot! Those fox ears and tails! I want to hug her!.........sigh, and I don't want her to hate me.........…. Well, I die once, so let not waste this; oh, but first I need to inform my wife") you then write massage to Ava on your HB. Otherwise...…..

"Darling~." You quickly look behind you. But fortunately, there no one there. "...…..I need a day off." You turn toward Kaguya, smile and stand up and went to sit next to her. You can see that she is shivering like a scared kitten.

"I I II I'm sorry. I dddon't have any experience in bed." (Kaguya) She struggles with her word due to her nervousness. Then you gently put your both hand on her shoulder, and she spooked a little by your action. Then you gently pull her toward your chest. Kaguya's mind was blank, and she realises that she is snuggling on your chest.

"It's ok....., just relax." You gently brush her golden hair down toward her back, and you keep repeating. Kaguya starting feel calm, and her body so stops shivering. You can see her fox twitching and her tails move a little. "Feeling better?" you look at Kaguya with a smile. She saw your smile, her face turn bright red, and then she turns away from you.

"Tony-sama is unfair." (Kaguya) She pouts.

"Why is that?"

"If you keep acting like this, I'm starting to like you more." (Kaguya) She buries her face against your chest.

"I feel the same way." You put your arm around her and gently squeeze her in. Then you and Kaguya stay like that for a while.

"Tony-sama. Please accept me as your loyal follower!" (Kaguya) she looking up at you.

"Are you really sure? I'm a human, just like those that destroy your kingdom. Also just met in two days. Shouldn't you wait a little longer?" she shakes her.

"Tony-sama, you're not them. Most important of all, you save us, give us food and home. To us, you are our lord we wish to serve with all of our heart and soul." (Kaguya) She let you go, and crawl toward the middle of the bed, then stood on her knee with her back facing and finally loses her kimono. She is now 100% naked.

You could see some fur on her back, back of her arms and fully cover her thigh. Then she turns and faces you with all of her glory: F-cup breast, curving waist and finally something you been expecting the whole time just as her animal features suggest. Kaguya has a canine penis with a lemon size balls, although it still sheath inside.

("Yep, she had a doggy dick....AWESOME!!") You read a book about beastkin sexual lifestyle, and they say that most of the beastkin had the genital as their animal counterpart. Not only that, but the book also noted that the Beastkin could actually impregnate a normal animal and get pregnant by one. But it must be the same animal type to work.

So if a Dogkin is mating a female dog, the female would give birth to regular puppy dogs and If with a male dog. The Dogkin would also give birth to a regular puppy dog and a 50% chance of giving birth to Dogkin baby. That why their whole race is called Beastkin.

"Tony-sama, take me." (Kaguya) She is opening her arms, welcoming you. You swallow your saliva and make your way toward her. she then put her arms around you and press breasts against your chest. You gently put one hand, her hips and one on her cheek.

"Tony-sama, do accept me?" (Kaguya) You could see those a twinkle in her beautiful eyes.

"How could I not accept a beauty such as yourself." Your face and her face are moving closer.

"Tony-sama, I'm so glad. Kiss*" (Kaguya) both of their lip press together. Both you and Kaguya are both gentle and slow, as if they both want to take their time and enjoy it.

After long kisses and loving embrace, Kaguya broke off you and slowly lay down on the bed; you quicky took off your shirt, pants and made your way to Kaguya. Then you both continued kissing but more passionate this time, with your hand playing soft breast.

Your hand run through her smooth belly until you felt a strange sensation on her stomach.

"This is? You notice there four shape nipples on her belly.

"Oh, those are my belly breasts...is it wired to you?" (Kaguya)

"Yeah, It's fantastic!" you quickly put your mouth over one of those belly nipples.

"Ahhhhhh~, Tony-sama don't- Ahhhhhh, that feel so good!!" (Kaguya) She bends her body forward from the intense pleasure.

"Mmmmm, give me some milk." You keep sucking none stop.

"There milk on my chest breasts, we canine race only have belly milk when we are pregnant ." (Kaguya)

"Then I will take on that offer!" you move to her chest breast and starting searching for her sweet milk.

"Tony-sama! Don't suck so hard~! There is plenty of milk so, please be genTLE~!!!!" (Kaguya) She moans in high while her head went backwards. You still suck on the delicious pink nipple with all your might.

"It here!! my breast milk is cumming~!!" (Kaguya) Then you felt a soft, warm sweet liquid enter your mouth. You slowly stop your sucking and gently drink from. The lovely smooth, silky taste flow gulp down your throat gives a wonderful feeling.

Kaguya raises up and seeing that enjoying her treat, she warming smile and place you head on her lap and let you enjoy drinking from her. "Tony-sama, drink as much as you want. I'm yours, after all." (Kaguya) She then notices your harden nine-inch member is twitching for attention. She smiles warmly and reaches out for your member.

After having sex with Ava, your penis has grown to nine-inch. You don't know if this is permanent or temporally.

"Ara, someone is getting jealous." (Kaguya) She begins to stroke your member as you moan in pleasure, Kaguya starting to move her hand faster. "Woow, Tony-sama's penis is beautiful.....So big, so thick, so hot!" (Kaguya) She licks her sexy lips in hunger. Then you moan, getting louder, which telling Kaguya that you close.

As you about to climax, Kaguya then let go of your cock. "?????.....Kaguya?" you let go of her breast and give her a sad confusing look in your eyes.

"Fufufufufu, My lord, allow me to pleasure you fully." (Kaguya) she got off the bed and got on her knees. You understand what she wants to do. You then move and sit on the edge of the bed. Then Kaguya moves toward your raging rod, demanding to be please.

"Siff* Siff* Ahhhhh, smell wonderful as well! Fufufufufu...my Lord, your loyal servant, would like to drink from your marvellous cock." (Kaguya) She looks at you with her pleading eyes.

"You may... and make sure to clean up after you finish." You let out a dominant voice.

"With pleasure, my Lord! <3" (Kaguya) She kisses the tip of your dick and starts licking your shaft as if she was licking a candy.

" Lick* Lick* Ahhhh...I never know that cock taste so good. Lick* Lick* Lick* Ahhhh, This is so addicting." (Kaguya) She stops lick your member and slowly pushing in her mouth. You moan with joy while playing with her soft fox ear.

"Ahhhh, Kaguya...your mouth feel so amazing!" you slowly move your hip forward, pushing your cock insider her. After your new nine-inch dick fully inside her, you lock eyes with each other and then she starts to moves her head.

"Ahhhhhh, You're so beautiful…..Mmmmm." you close your eyes while you caress her soft cheek. "AAAAAA! That it! I'm going to coming!!" you starting move your hips faster.

"Mmmm! Mmm! Mmm! Mmm!" (Kaguya) she moans while happy sucking your cock.

"I'M, I'M CUMMMING!!" you unleash your load in her mouth, and you could hear her gulping down your cum. You could even see your cum dripping from both sides of her mouth.

GULP* GULP* GULP* "Ahhhhhh!! I never knew that penis-milk is so tasty!" (Kaguya) She scoops up the dripping from her mouth and happily licks it all clean. "My Lord, I shall now clean your majestic member." (Kaguya) She came back to your semi-hard and licked all the white liquid off you.

As she still licking you, you notice a pink pointy penis is slowly emerging from her crotch sheath.

"Kaguya." You smile at her.

"Yes, my Lord?" (Kaguya)

"Get on the bed with your butt facing me."

"As you wish." (Kaguya) She quickly gets on the bed and four, with her sexy round ass facing you.

"….Beautiful." on top of her butt are nine fluffy foxtails. Next is her is anus and smooth wet pussy. And finally, her canine male part, which covers in light fur. "Look at you. Your pussy is soaking wet." You spread those wet lips open and start drinking pussy juice.

"Ahhhh! My Lord, Please use your thick hot rod and mate my wet pussy!" (Kaguya) She shakes her hips, inviting you. See how sexy she is. You quickly aline your cock against her vagina and slowly push it in.

"OO OOO OOOOHHHHHH!! So hot! Holy shit! So tight!!" thanks to Kaguya's juice, you easily slip inside her.

"AAAHHHHHHH!! My Lord! You finally inside me....I'm so happy!" (Kaguya) She rubs her belly where you cock is at.

"Kaguya, I'm going to move." You then start to move your hips back and forward.

"Ahhh, Fufufufu, Yes! please, breed this bitch in heat!!!" (Kaguya) She felt so much pleasure just having your cock in and out of her.

"Holy shit, she even tighter than Irin's squeeze mode. Kaguya might have the best pussy that I ever fuck." You start to move even faster while pulling her tails.

"MY LORD! MY LORD! MY LORD! AHHHHHHHH!! IT SO GOOOOD!!" (Kaguya) She was drooling while one of her hand is playing with her breast.

"Why don't we turn this up a bit!" you reach down for her erect doggy dick and grab it. Then you feel like your cock about to get a crush. "HHHHOOOOOOOLLYYYYYY!!!!" you yell in pain and pleasure at the time.

"Ahhhhhhhh! My Lord! My penis is very sensitive! If you grab it like I'm, I'm, I'M GOING TO CUMMMMM!!!" (Kaguya) You then felt a pulsing sensation from her doggy dick. You saw she is shooting a white liquid from her pink pointy penis. "AHHH!! AHHHH! AHHH! COMING FROM MY PENIS FEEL SO GOOD!!" (Kaguya) While she still shooting her cum you start to ram yours into her vagina.

"Oh, Kaguya, that was so hot! I think I'm getting close as well!" you notice that both of her arm and face collapse on the bed from overwhelming pleasure, but the thing you care about right is coming inside her. Then you begin to move faster and faster.

"Kaguya! Kaguya! I'm going to come inside you! Take it! TAKEEE ITTTTTT!!" you finally climax and release your load inside her hot, tight pussy. You were panting none stop while you're rubbing her nice soft ass.

"?...Kaguya? Kaguya?....did she fainted?" you gently shake her but there no response. "It seems she fainted." You went to check on her and saw she had a sleeping face.

"I need a drink." You got off the bed and took a glass and bottle of water out of your inventory as you pour water into the glass cup. As you drinking a glass of water, Kaguya is now standing right behind you, and you didn't notice at all.

"Ahhh! That refreshing!" you put the glass cup down, and suddenly Kaguya hugs you from behind in a forceful way.

"Kagu-MMM!??" She turns you face her and give you a deep kiss while one of her is rubbing your ass cheeks. And you also felt her pointy dick grinding between your ass.

"Kagu-KISS* I can't KISS* BREATH-KISS* MMMMMMMM!!!" You can't even breath from the forced kissing. Then you something pushing in your butt.

"AHHWOOOOOOOOOOOOOOO!!!" (Kaguya) She howls like a wolf when she full enter you, but the fox doesn't howl.

"OHHHHHHH GODD!! You felt her penis jab right in without thinking about your feeling. Then she put both of her hands on your waist and pounding you while she was kissing and nibble your neck and shoulder.

"Ah! Could it. Ah! Be? Lust frenzy?! Ohhhhhh!!" Lust frenzy is when a beastkin lost control of their mind due to overwhelming lust, and they would turn into a mindless beast who is only thinking about sex.

"Ahhhhh! This is actually! Ahhhhhh! My ass feels so GOOOOODDD!!!" She is pounding you so hard that your leg feels like jelly. She then hooks both of your legs up, carries you toward the bed, and puts you on four. Kaguya then continues to fuck you none stop while kissing your back and neck.

You felt so much pleasure that your turn bank. It like Ava all over again. Kaguya moves her hips faster and faster, then she swings her last thrust and releases her seed inside you.

"AHHWWWWOOOOOOOOOOOOOOOO!!" (Kaguya) She howls again with her hip lock against your ass. You turn toward her and saw her mouth were wide open and her eye roll backward. A few minutes later, you felt something strange inside your butt.

"Don't tell me!?" Kaguya grabs you're your ass with a firm grip and felt that there something stretching from the inside. "Oh, My God….she knotting me! OHHHHHHHHHHHHHH!! GGOOOOOOOOOOOODDDDDDD!!" The pain was so intense that you were clutching your teeth. You turn toward her and saw face was in bliss. Then the stretching finally stops, and you collapse on the bed with exhaustion, but Kaguya is not done yet. She changes her position by swings one of her legs around with her butt faces your ass.

And just what you expected, you and Kaguya are in an actual canine sex position, not a doggy style but ass to ass doggy sex. Then she starting raming with her knotted cock, by moving back and forward with her soft ass crash against yours.

"OH FUCK!! OH FUCK!! OH FUCK! This is how the canine beastkin sex!? It so fucking GOOODD!!" the pain from stretching has now been replaced with a new type of lust. On the other hand, Kaguya was in absolute ecstasy, her head rolls back, and her tongue is sticking out. In her beast mind, her only purpose right now is to breed you and empty all of her puppy insides you.

"OH SHIT! I'M GOING TO CUMMM!!" You unload your cum while Kaguya still ass humping you. She doesn't talk, but only a canine whining sound and howls. Then she is getting more intense and raming you harder and faster.

"AAFFFWWW!! AFFWWW! AFFWWW!!" (Kaguya) She was so wild that you wonder where is the elegant Noble Kaguya go? "AAFFWWW! AFFFWWW! AAAHHHHWWWWOOOOOOOOO!!!" (Kaguya) with a final butt slam. She pumps you with a massive amount of her hot seed inside you.

"AHHHHHHH!! HOLY SHIT!! ME TOO!!" you also climax while you feel a hot liquid flow inside you. A few minutes later, your whole body was so exhausted; your mind starts to fade away.

Kaguya turns her head toward with sad whining sound and then swirled her sexy round butt as if she were looking in a better position. Then she pushes her cock deep inside you, and her cock expand inside you for a bit.

"AAAFFFFWWWW!!" (Kaguya) She barks with a satisfying sound and then continues to fuck you again while you were already unconscious. You don't know what happens for the rest of the night, but you hear nothing but panting and howling.
