Natsuki giggles, not taking her hand away from your crotch. "We're just playing doctor, silly... and we have to check everything." She glances down at your cock, licking her lips again. "Maybe you should help us... take these off so we can see better?"

Akane nods eagerly, her fingers still tracing patterns on your skin. "Yeah... let us see..." Her voice is breathy and needy.

Natsuki pouts, looking disappointed at your hesitation. "But it's so much fun... don't you want to play with us?" She rubs her hand against your cock through your pants, teasingly. "It'll be our little secret..." Akane blushes and glances away shyly, her hand still resting on your leg.

Natsuki hums softly, her eyes drifting closed as she nuzzles into your neck. "We'll have so much fun," she murmurs contentedly, already imagining the future with you and Akane in it. "I can't wait to see what else we can do together."

Akane nods against your chest, her heart swelling with happiness and affection for both of you. She wraps an arm around your waist, holding on tight as if afraid she might lose this perfect moment if she lets go. "

Natsuki giggles at the overly dramatic statement, nuzzling closer to you. "I don't think that's quite necessary," she teases with a small smile. "But if it makes you feel better..." She glances over at Akane, who returns her look with an amused grin.

Akane takes your hand in hers and gives it a squeeze. "We appreciate everything you've done for us," she says sincerely. "

Akane watches in fascination as Natsuki teases you, her heart racing with anticipation and desire. She bites her lip, feeling herself growing wet between her legs as she listens to the sounds of skin on skin and your moans filling the air.

"N-Natsuki..." she whispers, her voice barely audible above the music. "Would it be... okay if I helped you?"

Natsuki looks up at her sister with an amused expression, arching an eyebrow. "I think that would be more than okay." She takes Akane's hand in hers and guides it towards your erection, wrapping their hands around you together. "Why don't we see how far we can take this?" she whispers before leaning in to kiss you again.

Their hands move in perfect synchrony, stroking up and down your length as they watch each other's reactions.

Natsuki: Her words muffled by your skin as she continues to suck and lick you, her tongue dancing over the sensitive head of your cock You feel so good, need more... Akane: Oh god, N-Natsuki... Mmmm... More please...

Her voice muffled by your skin as she continues to suck and lick you, her tongue dancing over the sensitive head of your cock N-Natsuki... it feels so good... Akane: Moans into your kiss More... need more...

"Mmmnnn... haaahh..."

Natsuki timidly raises her hand, "I-It's okay, Akane. Let big brother do whatever he wants." She blushes deeply as she glances away shyly.

Akane looks on, trembling in both fear and arousal. Her face flushes red with shameful desire.

Akane and Natsuki look at each other as they continue to pleasure you. Their eyes meet, communicating a silent agreement as they both lean in closer, pressing their bodies against yours. "We want this too," Akane whispers, her voice barely audible above the sounds of your sisters' pleasure. Natsuki nods in agreement, her breath hot on your ear as she sucks and strokes you deeper.

Their hands guide them closer, their wet heat pressing against you as they position themselves to join in on the fun.
