A dark haired beauty.

Amber, as I just found out, realizes I'm trying to hide and leans against the side of the pool, her lower body floats out towards me, effectively obscuring my lower half in the pool but at the same time trapping me between her kicking legs. The sight of her ass and her pussy peeking out from her bikini is not helping my throbbing hard cock.

"It's fine Ash, look who just showed up, our big step-bro." As she says it her hips drift down and she pushes her pussy back against my cock, oh this girl is evil.

"Oh, so this is him? Dad didn't mention you popping in" As I look her up and down I see her toned body, cute little ankle socks, loose fitting silky boy shorts, a very thin loose tank top barely covering her small but perky tits, her raven hair held back by a pair of headphones, a stunning angular face with piercing blue eyes. My cock throbs as Amber slides her pussy up and down my cock.

"Yeah he's going to be staying with us for a while I guess." Amber says as she just barely slides the head of my cock into her pussy, careful not to move to quickly, as her hips 'float' back towards me pushing my cock deeper "What, um, did you, mm, need?"

"Oh, uh, I was just wondering," I notice her looking at my body. "um if," her voice catching as her breath is a bit shorter, "ahem, if you could help." her nipples hardening and poking through the thin fabric as she locks her hands behind her ass and she spreads her legs just a bit, Amber pushes back driving agonizingly slowly another inch of my cock into her. I can now see up the leg of her shorts from my vantage and I see her smooth pussy slightly moist.

"With, mm, what Ashley?" Amber pushes off the edge of the pool driving my cock deep into her hot pussy. After all the teasing I'm not going to last much longer, and I seriously need to cum.

"Oh, mm with my, um, Yoga?" Ashley says as she pulls her hand behind her back and arches her back the thin fabric of her shirt pulls tight across her chest showing her hard nipples in detail.

Amber pulls off of my cock towards the edge of the pool till just the tip is just inside her pussy.

"Oh! I'm sure our BIG brother here" as she it she pushes back and pulls me in with her legs, driving my cock deep into her pussy. "ohhh, would be, mm, happy to help, wouldn't you?" As she plays that she's just grabbing me with her legs she drives, short, but deep thrusts. I feel her pussy pulsing and squeezing around my cock. Her pussy milks me as she cums on my cock.

This drives me over the edge and I start cumming deep inside Amber's pussy. I try my best to hide the fact that I'm cumming right here in front of Ashley deep inside her sisters pussy. I control the urge to thrust, I blink slow into the sun to hide my eyes rolling back. I look up and see Ashley expecting an answer. I try my best and stutter out "Oh, fuck yes, I'd, ugh love to mm, help you out."

"Really?! That's great! I still need to change though" she pulls at the waist band of her boy shorts as she says this causing the leg to pull more and letting the sunlight in. I see the light on her smooth mound and see her clit peeking out of her glistening pussy. I can't help but thrust deep at the sight spraying more cum deep into Amber. I don't know if Ashley is aware but right now I don't care.

"I'll go get changed then, and umm find you some shorts." Ashley says with what I think might have been a wink. As she turns I watch her sexy little ass walking away.

I grab Amber's hips and drive my cock deep into her eliciting a deep moan from her as her hips start shaking. Squeezing my cock as I pound her pussy hard and spray my cum deep inside of her. Our orgasms peaking all over again as Ash walks away.

"I'll leave you some shorts on the kitchen counter bro, meet me in the dance studio when you're dressed." Ash says as she turns and walks through the door.

"You should, mm, probably get dressed" She says winking back over her shoulder at me.

I pull my cock out of her still pulsing pussy, wade over to the edge of the pool and pull myself up. I locate the clothing I stripped out of, gather some of it and at least cover my crotch as I know the kitchen is right there. Then I realize I have no idea where this 'dance studio' is.

"Dance studio?" I look back at Amber and her glistening tight body, she points at what I knew to be the guest room. "Thanks, for not leaving me wanting there?" I wink.

"I told you I wanted to make you cum. Anytime, like really anytime?" Amber says as I stumble through the door into the kitchen. A pair of jogging shorts waiting.
