For quite some time, I just laid beside the girls like that, watching them make out. It was such a turn on and still amazed me the level of their comfort with one another. Avery would occasionally brush one of Kaia’s breasts, but most of that attention was going the other way.
Kaia broke off their kissing to nibble and lick her way down Avery’s neck and then down to the breast closest. She gave me a pointed look, then flicked her tongue across my sister’s nipple. I got the hint and positioned myself to join in on the other side. My cousin certainly hadn’t been kidding about how suckable they were. It was pure bliss taking the entire aureole into my mouth, kneading it with my tongue and lips.
Avery simply moaned at our combined efforts. Kaia and I, cheek to cheek, worked her over diligently, only briefly pausing to kiss one another. At some point, my cousin took my hand and dragged it down to Avery’s crotch. I don’t know if she’d already been touching my sister down there or not, but the panties were clearly soaked. I spread my fingers across her entire pussy and rubbed gently. Her legs tightened around my fingers and I immediately sensed hesitation coming from her.
“Whose hand is that?” Avery asked rhetorically. “Alex?”
“I put it there,” Kaia said, as if that made it all okay.
I looked up at my sister from where I’d been sucking her nipple. She looked down at me through slitted lids, pursed her lips, and sighed softly.
“Let’s leave the line at playing with my tits, okay?” she said without a hint of anger.
Honestly, it gave me a sense of relief. Now I knew where she stood on the matter. I wouldn’t have to worry if I was pushing things too far.
“Deal,” I said, quickly removing my hand from her crotch.
“You too, ‘cuz,” Avery said.
Kaia pouted but nodded in agreement. “Yes, dear.”
Avery rolled her eyes, then closed them fully as Kaia and I resumed our tag team assault on her tits. Kissing, touching, sucking, moaning — it went on for quite some time. At one point, I thought Avery might be close to orgasm without any direct contact below the waist. She seemed rather pleased with all the attention, and that was good enough for me.
We all cuddled with Avery in the middle for a bit. The girls kissed lightly every now and then. Avery never turned to meet my lips, though, and again I was okay with that limit. It somehow felt like it would be more intimate that playing with her tits.
“Feeling neglected yet, Alex? ” Kaia reached across Avery to run her hand down my side to my hip. My cock, which had flagged somewhat while we caught our breath, surged quickly back to full hardness. It bumped into Avery’s hip. If she noticed, she didn’t react.
I shrugged. “Not really,” I said. “This is already the best Christmas ever.”
Kaia grinned. “But it could be better. Much better.”
“If you say so,” I said, chuckling.
“Oh, I say.”
Avery groaned. “Geez you two. Can I leave?”
“Hell no,” Kaia said. “You’re staying and you’re participating, even if that’s only to watch.”
Avery’s smile told me she wasn’t that bothered by the absurdity of the situation. Not any longer, anyway. And me? Well, the idea had grown on me enough to have already shifted from impossible to inevitable.
