Offer them their clothes back.

“You two have put on a wonderful show, so I grant you back your vestments!” you declare officiously as you ceremoniously raise their rolled up swimsuit.

Abigail walks up and snatches her suit out of your hands and begins to dress.

“What about my outfit?” Carly grumbles as she covers her chest with folded arms.

“Alright, I’ll go find it...” you tell her, feeling a bit guilty about throwing it in the first place. You head off in the direction you tossed the skimpy fabric.

Unfortunately, you picked a dark part of the yard and it is impossible to see anything. You stomp around with your foot, hoping to feel a swimsuit over the soft grass. You then head over to the bushes and pat around, trying to angle yourself to get some moonlight on the leaves.

Suddenly, you feel something on your shoulder! You jump with a startle!

“Shhh!” hushes Lynn.

You squint to see the head cheerleader hunched down behind you.

“What are you doing?” you ask her.

She points back to the deck and whispers, “Just watch…”

You peer over and can make out Carly and Abi sharing a lounge chair. They appear very chummy right now.

“Did you do something?” you ask the mischievous blonde.

“I just gave them some space, you’re the one who started it…” Lynn replies.

You feel like a peeper, watching the two share an intimate moment. You can’t make out what they are saying to each other, but they are comfortably caressing each other’s thighs. It’s like watching a private movie with the sound off as Abigail leans in and gives Carly a kiss on the cheek. They converse some more and Carly looks even more shy now, but she still allows Abigail’s hand to run up and down her body.

Soon, Abigail is running her hands over Carly's body, fondling her breasts. You can’t turn your eyes away as Carly is laid back on the chair and Abi starts licking her friend’s tits. You feel a smack on your ass and jump, turning to Lynn.

“Sit down, this could be a while,” Lynn tells you. She’s seated cross legged and watching the show. You realize you’ve spent the whole time hunched over like a ghoul. You seat yourself on the grass as well and continue to watch.

Abigail’s hand has found its way between Carly’s legs and Carly is visibly writhing over it. They share a kiss while Abi fingers her friend. You feel fingers as well, clasping around your hardened dick. You turn to Lynn and she whispers in your ear, “This is getting me soooo hot….”

Your erection is evidence enough that it has done the same for you. You allow your classmate to give you a handjob while you watch the two girls across the yard. As Carly helps Abigail out of her Speedo, Lynn pulls down your shorts and climbs on top of your lap.

You feel Lynn’s juicy pussy squeeze around your shaft and let out a soft groan as she plants herself into a comfortable position. She wiggles her ass and leans back into you, with both of you facing the Sapphic action on the deck.

The girls on deck are fingering each other with urgency and Lynn matches the pace. Their cries become loud enough for you to hear at this distance. Lynn pulls your hands up to her breasts and you squeeze them gingerly as she bounces feverishly on your cock. With the cries of pleasure coming from across the yard, the two of you race to catch up, edging closer and closer to climax.

You hear yourself panting hard as you and Lynn fuck in the darkness, watching on at Carly and Abigail, now eating each other out in a sixty nine. Abi’s leg is up in the air and it twitches while her friend hungrily licks and sucks the pink flesh below.

Suddenly, there is a shout from behind the gate.

“Who’s there?!”

The girls on the deck shriek and scatter.

“Oh shit! The owners are home!” Lynn says.
