Joining the party.

The bickering between Piya and Lawan hits all the cadences and beats of every sisterly squabble, flitting between Thai and English as Piya continues the quarrel while she is looking for her bikini bottoms and putting them, hopping up once to pull them up before looking at the lines her bottoms made on her lean but well-curved ass.

I can see the raised skin, the red mark on her ass peeking out from where the fabric quits but choose not to say anything, rather get dressed into my trunks.

Lawan and Piya continue to talk faster and faster. My Thai remains rubbish but I have learned a few words and I can swear I hear Piya say the word for "horny" several times, each time getting a defensive seeming response from her younger sister.

Admittedly, I'd like to stay out of their exchange as best I can so I focus on getting myself dressed, covering up my cock, still slick and glistening from Piya's pussy.

Pulling open the drawer that Piya said my stuff was in I see two options. My typical trunks and the yellow and green Australian pride budgie smugglers Yui **** me to wear at the last party. The front and centre kangaroo emblem staring straight at me as I open the drawer.

"GAAH" I hear Lawan say, exasperated. "You always do this!"

I look up to see how Piya responds. Her chest and face still dripping with cum, gag in hand and flexing her jaw open and shut to loosen it up. "I always do what exactly?" Piya says sternly, "when was the last time you walked in on me getting blasted in the face with cum while wearing a gag? Because this feels like a first for me."

"It's not that..." Lawan says, losing steam, "Its just--"

Lawan loses her train of thought completely and starts laughing, causing her older sister to look my way as well and see me standing by the dresser in my yellow and green, super short, super tight trunks, my still not deflated post fuck erection practically ripping through the fabric giving the kangaroo a very deformed shape.

Lawan and Piya begin to laugh hysterically, clutching at each other to support their weight as they double over.

Piya comes over to me, planting a loving and lingering kiss on my lips, I can taste my own cum before she breaks away, "great choice honey. Yui is going to love that you're wearing that."

"It really looks good on you," Lawan says, her eyes laser-focused on my crotch.

"Let's not keep everyone waiting." Piya says while funnelling Lawan to the door, "God knows what Aor is telling them all."

I reach out and grab Piya's wrist and pull her back to me. She looks surprised and excited by what I might be doing but she protests, "I really don't think we have time for a second round."

I smile, "we can't have you going out to your party like this," and begin to wipe my cum off her chest and cheeks.

Feeling the sticky splatters of jizz wipe into and off her skin onto my fingers causes Piya to purr and I can see her nipples start to raise, outline through her bikini top. "I really don't think we have time for a second round my love," I say to her teasingly.

We follow Lawan down the stairs as she leads the charge to the pool. I watch her fit teen ass sway as she moves down the stairs and I'm holding Piya's hand the whole time.

The pool deck is littered with gorgeous women in bathing suits, in the pool and around the pool. All of them with drinks in their hands and it looks like everyone is here. Jess and Holly are with Becky in the shallow end talking with Aor and Dawn. A few of Piya's other friends are lounging on the pool deck sunning. All of them wearing the skimpiest of bathing suits and holding what looks like very large glasses of various mixed drinks.

The only person not by the pool is Yui and she is there, waiting for us all with drinks. "Here you go," she says, giving us each hugs and kisses as she hands the drinks to us. Each kiss getting bigger and deeper as she moves through us, first Lawan, then Piya. Then a long kiss for me, her tongue slipping into my mouth as she presses her fit body against me. "God! Why do I feel like I've missed you?" Yui says as she breaks the kiss and hands me my drink.

"Thanks, Miss Yui!" Lawan says as she takes a sip.

"Lawan it's going to get weird if you keep calling me that!" Yui says, "I've known you your whole life and we're out here drinking, barely dressed, maybe I'm not Miss Yui when we aren't a school, yeah?"

"I kind of like it," Lawan says defiantly into her drink, causing Piya Yui and I to exchange looks.

"Oh, Piya! You have something." Yui says, reaching up and wiping a missed bit of cum off of the corner of Piya's lip. Yui locks eyes with me before she sucks the cum off her thumb and then takes three steps and dives into the pool. I watch as her toned body, wrapped in a red bikini goes into the water and I chug my drink, look at Piya and follow Yui, diving in after her.
