You nudge Greg into thinking it's no big deal.

"Oh dear, let me grab a towel and clean up my baby boy's mess," Melanie says, joy in her voice. You lift yourself off her lap, but as she pulls back she surprises you with a small peck on the lips.

You don't let her go so quickly: bringing her into your arms you lock lips with her more fiercely, savoring her warmth and love. She lets out a surprised yelp, then relaxes and accepts the kiss for a few more seconds before tapping at your side.

You reluctantly let go and smile at her, your heart beating rapidly for this lovely, delicious woman. Her eyes shine at you with even more affection, and then she takes her leave to grab some towels.

Greg shuffles uncomfortably and clears his throat, quickly refocusing to the issue at hand, "What do you think about Gemma, son?"

You smirk a little, enjoying every little reaction, every moment of his discomfort.

With regards to the busty cop, you wonder how you could convince your new father to accept your relationship with her while also acknowledging her as your sister. While it may seem strange, you've already come this far developing this make-shift family... It doesn't matter whether you see Gemma as your sister or not: what matters is that the family recognizes it. You wanted to see how far you could take their interactions.

Of course, hearing Gemma call you "big brother" might be kinda hot, too.

Thinking back to Erica, you understand that her presence is accepted thanks to the power of her role as your slut; you don't plan on taking that approach with Gemma, though.

You try to push Greg with a comparison: "Dad, is it really a problem? I mean, you have no problem letting Erica be my sister..."

Greg frowns and raises an eyebrow, as if you're asking something silly. "Well, no, of course not. She's obligated to take care of you, since she's your personal slut. Don't tell me you're going to have this little girl be your slut, too?"

You frown as he dismisses your argument. Also, Erica taking care of you? You can't help but internally scoff. This lazy girl never really helped with the errands and taking care of apartment you shared, only splitting the bills as needed.

Erica looks away when you glance at her, as if she knows your thoughts.

Meanwhile, Gemma seems quite shocked by what Greg's implying. "S-slut?"

Hearing the worry in her voice, you rush to reassure her.

"No, no... Gemma, you're so much more than that, trust me! I don't think of you that way."

Hearing your sincerity, Gemma smiles sweetly and relaxes... But she's clearly still concerned and confused about her role.

Erica coughs. "I mean... It's not that bad. Besides, you've got to take care of your boyfriend's needs, right? What's wrong with embracing it?"

Gemma blushes and seals her lips, not willing to answer given how Erica might turn her words against her. She can't help but think back to earlier, when you made love for the first time. She's slightly ashamed to lose her composure, though it was your fault for teasing her.

You sigh, refocusing on the subject at hand. After a few moments, you decide to try a compromise:

"Dad, just think of Gemma as your daughter-in-law. Just like with Erica, I want to have a close relationship with Gemma. It shouldn't be a problem if I want her to be like a little sister, at least while we're together as a family?"

Greg furrows his brow, thinking deeply and hesitating before answering. "I... Well, uh... I suppose?" Then he relaxes a bit, and grins at you. "Daughter-in-law, huh?"

Gemma's face flushes further, understanding what you're implying. Before she can open her mouth, you preempt her with some reassurance. "I mean, it's too early for that, of course but... All I'm saying is that... That I'm serious about Gemma."

While it's a little embarrassing to say it out loud, there's truth in your words. It's not every day that you meet a busty, petite police girl. Despite being a woman of the law, she feels more like a rabbit... Which makes you the wolf. You want to taste her as much as possible, sure, but at the same time... Her personality and appearance makes you want to cherish her, too.

Melanie comes back in time to hear your resolution. She interjects, in a huff: "That's right, it is too early! Mommy still needs to spend a lot of time with her sweetie and her new girls! We can all agree to love each other, right? The rest is... Details."

You stare at her bare, jiggling jugs as she towers over you, beginning to wipe down the couch and your nether regions. You shiver in delight as you feel the wet cloth sliding over your bare skin.

Greg hums, nodding in agreement with his wife. It seems her words (and yours) have convinced him somewhat.

"Alright, fine," he declares, before focusing on Gemma with more reassuring eyes. "...Gemma, you can call me 'Dad' if you like. If my son is this serious about you, then I have no reason to get between the two of you. Regardless of your... Unique relationships with my son, you and Erica are now part of our family. I think that should be enough."

Gemma smiles meekly; while still unsure about this entire situation, she's definitely happy to hear those words.

"Um... Thank you, Daddy... Mommy..." As she speaks, her new parents grin and nod encouragingly.

Checking the time and eyeing the stove that she left on, Melanie pipes up: "Well, it's been a long day, and dinner's almost ready. Why don't we move to the table?"

As everyone gets moving, Melanie finishes wiping you down. Then she places her hand on your cheek and gets up, heading for the kitchen. Greg trails after her, clearing his throat.

"Um... Honey, are you going to put some clothes on?"

Melanie chuckles, shaking her head. "I have to be ready, in case any of our children need some milk."

She glances back at the three of you. Erica can't help but shiver in delight, while Gemma gulps nervously.

"Oh... Of course," Greg replies uncertainly. "...But do take care of yourself, hmm? I don't want you to catch a cold."

He slides his arm around his wife's waist as he walks with her. Melanie smiles, leaning in to kiss her husband.

As they drift further into the kitchen, their voices becomes quieter... But you don't need to hear their words to know that Greg is putting the moves on Melanie. His hand moves down her side, then further, cupping her shapely ass...

You watch the interaction carefully. Melanie giggles, politely declining her husband's advances. Then she says something, and he begins helping her set the table.

For a moment you're lost in thought, considering your "father" and his role in this new family... But Erica's voice snaps you back to attention.

"So... Now that Daddy is in-the-know, we're officially a family, right?" Erica moves to you side, flopping onto the couch.

You smirk, glad to see your cousin enjoying herself so much.

"Well, you and I have always been... For better or worse... But yeah."

Erica scoffs at your attitude. "Just because I'm your slut doesn't mean you have to be mean."

You shrug, unable to hide your smile. Gemma giggles, feeling a little more at ease now; that doesn't last long, however, as you lock your gaze on her. Although you're only wondering what to do next, Gemma mistakenly feels as though something's expected of her. Her eyes slowly converge on your crotch, where she sees your half-hard cock.

She hesitates before taking a deep breath, getting up, then moving to your other side. Then she surprises you by leaning closer, embracing your arm.

"Um... Big brother? Do you want me to help you down there, like Mommy did?"

You blink, staring at her in astonishment. Then your erection twitches, quickly rising to full mast.

"Wow, Gemma... That's... Perfect."

She blushes, then turns her face away. "I-I'm trying here. You don't have to--"

You stop her short by placing an arm around her slim frame, groping her breast. She keeps her face hidden, but otherwise fully leans in to your advances with a slight moan.

"You're so precious," you whisper, kissing the top of her head.

Erica coughs, breaking the moment. Refusing to turn invisible and lose to her new sister, she grabs your other arm. "I don't think so, Gemma. I'm the elder sister, and his slut. I have a responsibility to handle this."

As you turn to look at her, she leans in and ambushes you with a kiss. Uttering a surprised grunt, you have **** but to melt into her embrace as her tongue dances with yours. Gemma turns and watches, her mouth hanging open.

Your cock twitches, leaking pre-cum. That doesn't get past Erica, who slides her hand down and grabs your member.

You flinch as she begins stroking, unable to resist your personal slut any longer. Still kissing her, you turn over and straddle her body. Then you slip a hand under her skirt, reaching up to cup one of her breasts.

Gemma has **** but to move over as her "brother and sister" take up most of the couch. Erica's clothes fly off in mere seconds... But before your new girlfriend can take in any more of the show, Melanie calls out to her:

"Gemma, sweetie, would you mind helping your father set the table?" Glancing up, you realize that both of your parents can see you... But neither bat an eye.

Gemma, however, takes one more look and frowns before hopping to her feet. You can see the jealousy on her face, but Erica seems to have succeeded in boxing her out... For now.
