“She digs her heels into your buttcheeks as your thick cock splits open her folds, harder... deeper... wetter... until you're all the way inside your sister.”

My girlfriend paused to catch her breath and soak in the feeling of having me fully embedded inside of her. And then she kept going. "Once you're inside, she drops her legs to the side to let you control the pace and the depth as you lift your chest up to stare down at her pretty face and perky breasts."

I did as she said, arching my back away.

“And while you do that, I take advantage of the room to straddle her face and Lower my pussy to her talented lips. I'm facing away from you and bent over, my face mashed against the mattress while I reach back with both hands and spread my asscheeks wide so you can see the winking rosebud of my asshole, which you plan on fucking next. And while you drill in and out of Danielle, I'm trembling on her face as she licks me to orgasm after orgasm..." She trailed off as the pleasure emanating from our joining momentarily disrupted Brianna's concentration.

“Oh, fuck..." she cooed.

I could see Brianna's beautiful body beneath me, her halo of dirty blonde hair spread across the pillow and her green eyes piercing into me. And then I let my eyes unfocus just enough so that I could imagine it was Danielle I was fucking and I could visualize Brianna bent over, just as she described.

We'd been on the island for two days already. Our time so far had been spent sunning ourselves on the beach, eating, and lots and lots of fucking.

It was the perfect vacation.

Presently, Brianna was on all fours, her head hanging down between her shoulders as she impatiently wriggled her ass in my direction. There was a creamy white trickle running down her leg as my Latest climax leaked out of her sodden pussy. I finished lubing her asshole and fisted my reborn erection, placing the tip to her tight anus and gradually pushing through.

“Oh, fuuuuuck, honey... I've got your sister beneath me while we sixty-nine, her mouth is in my crotch as she slurps your cum out of my slimy, wet cunt. 0h, oh, oh!" Brianna began to chant as I started ina familiar pumping motion, her tight anal walls clasping at my rod as it stroked in and out of her.

“Fuck my ass, David... Fuck my ass..."

I was doing just that.

“Fuck my ass... Fuck my ass, little brother..."

I blinked, and as the dirty blonde head turned around, it was

Danielle's face I saw screwed up in pleasure as I reamed her out. "Oh, yeah!" I growled and really began pounding her asshole.

“Fuck, fuck, fuck, fuck, FUCK!”

She tensed up and came, arching her back as her head thrashed around, sending blonde locks every which way. And as her muscles clamped down on me, she pulled me with her and I ejected blast after blast of scalding jism deep into the depths of her anal cavity.

Before I finished, her legs gave out and she collapsed. I fell down with her, my cock still buried in her rectum and spewing out more cum.

And then we were done, panting deliriously. My throat felt raw, and belatedly I realized I'd actually been screaming as I experienced the biggest orgasm I'd felt in a long time.

Brianna hummed happily as she felt my weight crushing her to the bed. I went to move off of her but she whined until I settled back down. And when she caught her breath she giggled, saying, "I'll bet the neighbors got a real kick out of that."

As much as I wanted to, man does not Live by sex alone. And besides, we were on a beautiful island and I didn't really want to miss out on everything it had to offer.

I thought we'd finally found a comfortable rhythm to our relationship, and it showed in the way I was much more attentive to Brianna, more empathetic to her moods and needs. I couldn't let her down. As I watched her dirty blonde hair flashing in the sun, I hummed happily with how much I loved her.

During the day, we bonded over hiking and snorkeling, sharing the physical challenge and the joy of discovery. During the afternoons, we hit the towns to shop for trinkets and took romantic walks on the beach. During the evenings, dinners became ritualistic seduction instead of just feeding times. Brianna especially got a kick out of sharing a lava flow with two straws.

I will say this, having sex in a tropical pool may Look wonderful, but it's really impractical. Don't get me wrong, despite the cool water, having a naked Brianna undulating beneath a waterfall had me harder than a tire iron. But the water isn't really good for Lubrication and the footing is sketchy at best. We managed to make it work, but I wouldn't be in any hurry to try it again.

It was Day 7 of our weeklong vacation. Tomorrow, Saturday, we would be catching a red-eye to return us to the mainland, our jobs, and the rest of the real world. Brianna and I were cuddled together in a hammock in the shade, Lightly dozing while enjoying the trade wind breezes. I was idly planning the next adventure. We'd summitted Sleeping Giant and photographed Spouting Horn. We'd snorkeled at Ke'e and ridden ATVs all over Kipu. I'd been reading something about Ziplines, or maybe springing the extra money for a Helicopter tour.
