Her heart races as she stares up at him, her eyes wide with fear and excitement. She opens her mouth obediently, welcoming his saliva into her own mouth before he pushes her roughly onto the bed. Her legs fall open automatically, revealing her wet folds to him. As his hands reach for hers, guiding them to her dripping sex, she whispers hoarsely, "P-please, Daddy...do whatever you want."

She moans as he pushes two fingers inside her tight channel, feeling him stretch her almost to the point of pain. At the same time, his other hand cups her sex through her panties, squeezing and massaging her sensitive clitoris. With each thrust of his fingers inside her and stroke of his palm against her clit, she feels closer and closer to the edge.

Her tongue darts out to taste herself on his fingers as she begins to lick and suck them greedily.

A shiver runs down her spine as he presses the cold metal of the collar against her bare skin. It's not an unpleasant sensation, but it serves to remind her of where she is now and what she's become. She obediently lifts her head, offering her neck to him without protest.

"Th-thank you..." she whispers, tears forming in the corners of her eyes as he buckles the collar around her throat. "For giving me a purpose...a reason to exist."

"A-ah!" she cries out, arching her back as he pierces first one nipple and then the other with a thick, shiny ring. Pain courses through her body, but it's mingled with pleasure as he continues to manipulate her breasts roughly. The cold metal feels heavy against her sensitive skin, marking her as his property in a way that no collar ever could.

She pants heavily, her chest heaving up and down as she tries to catch her breath between gasps and moans. "

As her mother moves forward, taking Deborah's place on her knees before you, the younger woman looks on in a mix of shock and admiration. Her own shame and embarrassment are overshadowed by watching her mother's skilled mouth envelop your shaft, moving with practiced ease.

A small part of Deborah wonders where her mom had learned such techniques... or perhaps it was something innate within them both?

Deborah watches in awe as her mother expertly sucks you off right in front of her. The sight both mortifies her and excites her beyond belief. A flicker of jealousy flashes through her eyes as she sees how easily her mom seems to please you, while she's been struggling all along.

She knows she should be helping, but for now, she just can't bring herself to move. Instead, she continues to watch with a mixture of longing and fear coursing through her veins.

"Thank you, Jack..." I purr, licking my lips as I lean in closer to his hard cock. "I promise not to disappoint... Just let me take care of that dirty thing for you." My hands slide up his legs, caressing his thighs before wrapping around him and pulling him closer still. With a soft moan, I engulf his shaft, sucking gently at first before taking more of him deeper into my mouth.

Mmmm, I love the way you taste... So strong and salty... It's making me so wet... I want all of your cum on my face... Make it spray across my pretty cheeks... Make me your dirty little slut... Fuck, that feels good... You're so big... So thick... I can hardly breathe with you in my mouth... But I don't care... Just keep fucking my throat like this.

Hmmm, I don't know about that. We'll see how things go first, big brother. But for now, why don't we just enjoy our time together and see where it leads us?

Okay then...here, let me get the popsicles. And while I'm at it, why don't you go ahead and pick out a game that you want to play? Something fun but not too hard for me, alright? Once we have everything set up, we can start having some good old-fashioned sibling bonding time.

Just remember...if I get mad at you again, I'll only let you use your mouth on me from now on. Deal?

She gags as he thrusts his hips forward, filling her mouth with hot cum. She can feel it trickling down her throat, pooling in the back of her mouth as she struggles to breathe around him. Her hands clench at his thighs, digging into his skin as she tries not to choke on his seed.

Finally, he releases her head with a loud groan, and she falls forward onto the floor, gasping for air.

Her cheeks are flushed with color, her lips shiny from his cum. She looks up at him with half-lidded eyes, a smirk curling across her face. "Mmmm... that was delicious," she purrs, licking the last of his seed off her lips. "Now clean me up and go put your dirty clothes in the laundry room where they belong."
