Hot Summer Job/Get Kylie to back you up
"I could use some help here, if you hadn't noticed," you say to Kylie while Larissa taunts you with song.
"Ummm... sure."
Kylie shifts on the couch, making a move to stand. You pull your hand away, no longer concealed between her legs. But she doesn't move very far. She leans into you, kissing you sweetly while giving your cock a firm squeeze. Any protest you might have offered melted away when her lips and her hand acted so harmoniously against you.
The moment is short, but it's enough to shock the girls into silence. Kylie pulls back slowly, releasing her hold of you as she licks her lips.
"There. We kissed."
Not the help you were expecting. In fact it's not even remotely helpful in that regard.
"See! See! I knew it!" brags Larissa.
"That's gross." Bree crosses her arms, looking more annoyed than disgusted.
"Rylie and Kylie, sittin in a ..."
Kylie moves to the edge of the couch, running one hand through her hair. "You think kissing is gross?"
Bree doesn't reply. She just glances between Kylie and you.
"You just haven't kissed the right people," continues Kylie. She smoothly transitions off of the couch, kneeling on the mattress in front of your sis. "Namely... me."
The horny redhead reaches up and grabs the back of your sister's neck before eagerly locking lips with the younger girl. Bree looks shocked, her eyes opening wide and hands shooting forward onto Kylie's bare midriff. But she quickly changes her mind and her mood. All of 5 seconds into the kiss and your sibling's eyes shut tight, her mouth moving frantically to try to keep up with Kylie's apparent experience in this area. Kylie moves fluidly and sensually, shuffling closer and allowing her fingers to roam upwards into Bree's hairline.
"EEEWW!" protests Larissa. "You're not supposed to kiss other girls!"
Kylie breaks herself away from your sister but doesn't let go of her. "Why not? I think it's nice." She lightly pecks Bree's awkwardly pursed lips bringing a smile to both of them.
"You're just not supposed to!" Larissa states so assuredly.
"That sounds like a stupid rule. And I can prove it to you."
Kylie moves towards her sister. The spry blondie takes up a defensive position, hands poised for grappling.
"You can't make me!"
Kylie just grins. She grabs her little sister's hands entering into a brief struggle. It doesn't take much for Kylie to overpower her smaller sis, forcing her hands up into the air and then pushing her back onto the mattress. Kylie swoops down onto her sister, hands locked above their heads, and forces her younger sibling to make out with her.
"Ky... quit... is not... hmmmm..."
Larissa squirms a lot longer than Bree which makes Kylie that much more passionate. She chases after her sissy's mouth, locking lips only fleetingly at first. With her arms locked on either side of her head, Larissa can't escape the barrage. The youngest of the group looks especially amazing in this position compromised position, her shirt raised with her arms to expose her bellybutton, her stomach pulled taut and accentuating her hip bones.
The combative sisters make out for nearly 30 seconds before Larissa finally gives in and lays still, accepting and embracing her new submissive state. With all resistance gone, Kylie's hands slide down the full length of Larissa's prone arms and wander onto the girl's torso, roaming between her flat chest and subtle hips. She tongues the frozen girl's pensive lips, unconcerned by the comparative lack of animation. Larissa yielding at all is proof of her participation in all this, but her soft moans don't hurt either.
Watching Kylie and Bree kiss was hot in an innocent tender way, but witnessing the desire and lust radiating from these sisters splayed out in the middle of the room is nearly enough to make you whip your cock out and beat it right here.
"Um, a-are you allowed to kiss your sister like that?"
Kylie gently gnaws on Rissa's bottom lip before righting herself with an exhaustive sigh.
"You can kiss people however you want, as long as they kiss you back."
"You made me kiss you," Larissa points out while making no effort to move from the mattress.
Kylie plays with her sister's exposed belly. "Shuddup. You liked it."
"Did not."
"Did too! Although I bet you'd like kissing a boy even more."
Larissa looks over in your direction and smiles.
"No! You're not allowed to kiss my brother!" declares Bree, taking a stand.
"And why's that?" Kylie shoots back. "You trying to keep him for yourself?"
"No, I, er... he's my brother..." she repeats, as if that someone explains everything.
