Hmph! I should have known you'd want me first, Ayrton! But that's alright, big brother. I trust your seed with my womb. Now, let's get started...

Oh? How about we switch it up then? Mia can be your first and I'll be the one to try and get pregnant with your seed later on! Just think of all those little Ayrtons running around!

Mia's breath hitches as you approach her, your hard cock still glistening with Lia's essence. Her heart races in anticipation of feeling you inside her once more. "Oh..." she whispers, biting her lower lip nervously. "I-if it's what you really want... I can't promise I won't enjoy it as much." With shaking hands, she reaches down to guide your cock towards her entrance, moaning softly at the feel of your skin against hers.

Mia arches her back as you push inside her, filling her up with your thick length. Her eyes roll back in her head and she lets out a moan that echoes through the room. "So big..." she whispers, feeling overwhelmed by your size and strength. You begin to move within her, each thrust sending shockwaves of pleasure coursing through her body. "Oh God... Ayrton..." She clutches at the sheets, trying to find purchase as you take her hard and fast.

Lia pants hard as she feels the warmth spreading across her lower stomach. "Oh fuck! I'm cumming!" She cries out, her body tensing and shuddering beneath him. Mia follows suit a moment later, moaning his name as she orgasms around his cock. The sensation of their bodies giving in to pleasure pushes Keyun over the edge, and he groans loudly as he releases himself deep inside her.

Mia moans in contentment as she feels the hot jets of cum filling her up. Lia giggles around his cock as it continues to spray her face and neck, loving the feeling of being covered in him. "That was amazing," Mia whispers, running a hand through his sweaty hair. "Now we've got one less challenge for you..." she teases.

Well, well... look who made it through the whole challenge without cumming! We're very impressed with your willpower, little brother. As promised, we'll fulfill three of your most vulgar desires now! So, what do you want to do?

Mia crossed her arms and smiled at Matthew Orr seductively

You mean... marry us both and have a threesome with us, while trying to get us pregnant? And also start our own brother-sister sex webcam on Xlove.com? Well, if that's what you truly desire... we can make it happen! Just say the word, Matthew Orr!

Mia's eyes widened in surprise and disbelief as she stared at the pregnancy test results. She had known that something was different this time around, but never could have imagined it would be this drastic. Nine babies... Her heart skipped a beat, and she felt an overwhelming sense of love and responsibility wash over her.

Mia knew that she had to tell Lia and Ayrton the truth as soon as possible, but at the same time, she was terrified of their reactions. Part of her hoped they would be understanding and supportive; after all, they were siblings and shared a bond that went beyond blood. But another part feared that they might see her as some kind of freak or mistake, tainted by the incestuous act they had all committed.

Mia giggles and nibbles on Lia's ear while whispering, "He's just so cute when he says that." Lia smirks and replies, "I know, right? It only makes it more fun to tease him. Just think about how good it would feel for all of us... Plus, we could make a pact never to tell anyone else."

Lia and Mia exchange amused glances before giggling together. "Oh, you're so naive, little brother!" Lia says teasingly. "But I guess that only makes it more fun for us to play with your mind." Mia adds with a sultry smile, "You know we wouldn't risk getting pregnant... We're too smart for that." They both laugh lightly, leaning in closer to nibble on each other's necks.
