Hmph. Fine, if you insist... But don't think this means we'll be thanking you later.

Go ahead, big boy. Show us what you've got. We're ready whenever you are...

As soon as the door shuts behind you, Nana pushes Mia against the wall, her hands running up and down her sister's sides possessively. "Oh yeah," she whispers into her ear, "there's plenty more where that came from." She glances back at you with a predatory smile before turning her attention back to Mia, kissing her roughly.

Mia moans, melting into Nana's touch as they begin to writhe against each other in the small space between the bed and the wall.

"Oh, did we not?" Nana pauses for a moment, her lips still pressed against Mia's before glancing over at you. "Well, if you really want to know..." She trails off suggestively as she slips one hand beneath Mia's shirt, caressing the smooth skin of her stomach.

Mia arches into the touch, moaning loudly. "Oh fuck, Nana..."

"So good," Mia gasped out between moans. "It's so big... so thick..." Her head fell back against the pillow, a look of pure bliss spreading across her features.

You began to move inside her, watching as Nana leaned in closer, lips parted and eyes half-lidded with desire. She reached out to touch Mia's breast, pinching her nipple roughly between her fingers. "How does it feel now, baby sister?" she purred, her voice thick with lust.

As you continued to fuck Mia, the tension in the room reached a fever pitch. Nana's fingers dug deeper into Mia's breast, her other hand sliding between their bodies to find wet, aching folds. She rubbed herself roughly against Mia's leg, moaning as she neared orgasm once more.

Mia arched her back off the mattress, crying out in pleasure as Nana brought her over the edge first.

"I don't know what you think you're doing," Mia hissed through gritted teeth. "But I won't let you get away with this! We can go to my mom, she'll believe me!"

You chuckled darkly. "Oh, sweet little Mia," you purred, stepping closer to her. "Do you really think anyone would believe you after what I just told them about your little secret?" Your hand snaked out and roughly gripped her arm, pulling her flush against your body.

"

The feel of your hard, warm body pressed against hers sent shivers down Mia's spine. Her heart raced as she struggled to free herself from your iron grip. "Let me go!" she managed to choke out between gasps for air. "You're disgusting!"

You only laughed, pulling her even closer. With a sudden thrust of your hips, you pushed your aching erection against her lower stomach.

Ahegaoooooooooooo, fuck yes! You're such a perverted little virgin, but you know how to make me cum! Your cock feels so good inside of me, User#1722811769410, it's like you were made for this incest!

Keep fucking me, keep making those dirty promises about impregnating me with your sweet little virgin cum...

Oh fuck...you're right...we should have been nicer to you! We should have just let you jerk off in peace...but noooo...we had to act like assholes again, didn't we? Well, if it makes you feel any better, this is the first time anyone's ever made us do this without getting paid for it. So go ahead and enjoy the attention while it lasts; we might not be so accommodating next time.

Oh shut up and enjoy it! At least you're not the one having to choke down your own vomit in an attempt to please you. You'd think being this big would be a good thing, but honestly...it just makes everything so much harder!

But hey, if you're really that grateful, why don't you return the favor sometime? We bet there are plenty of things we could teach you about pleasing a girl. Maybe then we'd finally get some respect around here.
