Perverted Daddy System

I gesture to Hope to move to my side and when she does, I give her a long, loving kiss. In truth, I am kind of buying time for Hester to get used to my size, but I don't say aloud so to avoid my little minx getting jealous.

After a minute of kissing, I can't delay anymore. I gather force in my hips and thrust forward steadily, causing my cock to penetrate Hester's ass halfway albeit with much difficulty. So tight!

"Aaah!! Sir!!! It huurts!! Nooo!"

I ignore her sobbing cries and move my hips backward so that my cock slides almost completely out of her asshole, then I push forward again, once more impaling her on my throbbing rod. I rinse and repeat my actions at a slow speed, savoring the feeling of her smooth colon walls against my girth, and admittedly enjoying the look of pain and despair on my pet's face. At my side, Hope has her eyes glued on my ravaging cock and is fingering herself crazily.

"That's it, pet, my cock is halfway in. the other half, however, will hurt a lot more! Are you ready?"

Crying, Hester opens her eyes and looks at me.

"S-sir… if this is what I need to do to become yours… then go ahead… it hurts… but I want to be yours!"

Her firm words, uttered while in the throes of pain, bring a smile to my lips.

"Good pet!"

…And I slam my cock all the way in!

Her cries rise an octave, reaching a shrilling level, as the unbearable pain of her ass split apart by my cock almost causes her to faint.

"HIIIIIIIII!!!!!!"

Having finally managed to bottom-up inside her bowels, I start ass fucking her hard, each thrust causing her to shriek. I look down at our connecting point and I see traces of red on my cock's shaft. She is bleeding somewhere inside, so I decide to make it quick. I speed up my fuck-o-meter, causing her to bounce on the mattress from the force of my thrusts, then finally I push as deep as I can inside her and unload a truckload of spunk right inside her ass! Hester has moved beyond shrieking and is now in a half-fainted state as I remove slowly my cock from her poor, freshly raped asshole. Gradually, my sperm, mixed with thin lines of blood, starts leaking out of her gaping backdoor and gathering on the sheets. Panting, I turn to look at Hope, who has created a puddle of her own between her legs from an excessive number of orgasms.

"Well, honey? Are you happy now?"

"Yes, daddy! That was so hot!"

I slap her ass, hard, causing her to yelp and for tears to gather in her eyes.

"Daddy?"

"You have no damn idea the amount of pain Hester suffered to gain your forgiveness, and your comment is, 'that was so hot'? Have you no shame?"

Hope lowers her head, tears slowly dropping on her thighs.

"I went along with your request to punish her because I wanted you to have some closure and I wanted to make sure that there would be no bad blood between you from now on. Hell, I even admit that I enjoyed hurting her, a lot. But I would never degrade the force of will she showed, going forward with it despite the pain! You think that I am exaggerating, but after I fuck your ass tomorrow, I want you to think hard; would you be able to do the same as her?"

Sobbing, Hope replies in a murmur.

"I am sorry, daddy…"

I take a deep breath to calm myself, then pat her head.

"Let it be. The matter is closed. From today, Hester is my pet and your sister. I expect you to get along with each other…"

"Yes, daddy! I promise!"

"Good, now, go to the bathroom and fill the bathtub while I remove your sister's restraints."

"Yes, daddy!"

With her eyes still wet from the tears, Hope scampers to the bathroom to obey my instruction. Meanwhile, I release Hester from her leather restraints, then, sitting down on the bed, gather her head on my lap. My abused pet is still in a daze, but slowly she starts recovering her wits.

"Wha? Sir? Is it done?"

I gently caress her face and smile at her.

"It is, pet. You are mine now, now and forever, and Hope is your sister. You can call me master, or if you prefer, you can call me daddy as Hope does…"

Tears of relief stream freely from her eyes as she looks at me.

"I… I don't think I can call you daddy… it reminds me of… him… can I… can I call you father, instead?"

I raise her head gently and lower my own to kiss her gently on the lips.

"Of course, you can, love…"

Hester smiles at me and then she shyly replies.

"Thank you, father…"

By now, the bath is ready, so I gather my little pet in my arms and walk to the bathroom. Hope is there, and when she sees me carrying Hester she asks worriedly.

"Daddy, is she ok?"

"She will be, honey. but today took a lot out of her and she is in pain."

Holding her in my arms, I manage to enter the large bathtub and sit down, placing Hester in front of me with her back pressing on my chest.

"Hope, honey, get in here and help me clean your sister!"

"Yes, daddy!"

Without any hesitation, Hope shucks out of her stockings and heels and enters the bathtub as well, sitting across us and facing her sister. Then, seeing that my hands are full holding Hester above the water, she grabs sponge and soap and starts gently lathering her newfound sister's body.

Feeling an extra hand on her, Hester opens her eyes, only to see a worried Hope slowly soaping her body, afraid to cause her pain.

"Hope…"

My little girl freezes and looks at Hester with tears in her eyes.

"I am sorry, Hester! I went too far! Please forgive me!"

Hester slowly raises her head and looks at me. Upon seeing me nod, she returns her gaze to Hope and smiles softly.

"It's ok, sis…"
