Offline/Offer Asha some deep tissue action
After a brief dramatic paddling of your sister's ass, you turn to your cousin. "Hey Asha, wanna try some shee-at-soo?"
"Umm... no, that's okay." She really did think about it.
Emma is a little more insistent. "Yeah! C'mon! You get a turn too!" She wiggles her way out from under you then hops over to pull Asha to her feet, guiding your cousin onto the sleeping bag. Asha tries to lay down on her stomach beside you but you redirect her legs to slip between your own before you outright sit on them to try to keep them pinned down.
Sliding along Emma's bed caused the shirt Asha is wearing to rise just enough for you to see the bottom edge of her bum. That's enough of an invitation. Without asking, you grab the hem and force it up her body, revealing first her full little ass followed by every progressive inch of her back.
"Justice really likes seeing girls naked!" announces your sister, sounding weirdly proud of that tidbit of knowledge. She may be trying to explain this fact to Asha, but she's staring with interest at your stiff cock when she says it. She also makes a point of adjusting her posture at the same time, straightening and opening up her threadbare body for whoever might want to look. Asha just glances over her shoulder, eyeing up your face and your cock with equal measure.
With a guilty smile, you push the top all the way up to Asha's shoulders, the fluid reveal of her figure proving to be very satisfying. She has propped herself up on her elbows similar to how Emma was so it's not hard for you to fully push her shirt off of her shoulders as well, the top hanging down her arms but still held by her neck. But what is very hard is your cock.
As you lean into her those extra few inches to finish adjusting her top you feel your tip slide into Asha's warm flesh. You actually notice the wince on Asha's face before anything, but it's an easy set of dots to connect. A glance down and you see your head nestled between her legs making contact against her underside. When you lean back you open her cheeks and watch as a thin string of precum droops in the air between the two of you, bridging your glans to her asshole.
It's fucking tempting to just drive it home right there, but you keep up the fun and pat your palms along each side of Asha's ass and hips sending her bum jiggling. Emma emphatically joins in, slapping her friend's back, head and face in a flurry of crazed activity.
With your sister serving up a wild distraction, you slip your thumb into your cousin's butt crack and plant it directly against Asha's tightly puckered little hole. rub your personal lubricant into her. She definitely notices, squawking and swiping one hand behind her blindly, but is too busy with the torrent of giddy slaps from Emma to really do anything. In fact she mostly just clenches her teeth and puts her head down to avoid Emma's face slapping, her body tensing up. Pulling one half of her bum aside, there's clearly some excitement. Asha's backdoor visibly clenches and relaxes over and over while you run your finger around and around her rim, both her cheeks flexing under your stimulation. It's surprisingly fun watching her backside squirm and twitch under your touch but you decide to relent a little and leave her asshole alone for now.
A firm squeeze of Asha's cheeks help you fully appreciate your little cousin's full backside. It's not a massive booty by any means but, unlike your sister, Asha's ass is more than a mere handful. You admire your cousin's rounded butt with a wide spread and greedy grip, working her cheeks like warm dough. Tracing the roundness of her butt, peeking on her pussy further down between her thighs, every single bit of this is captivating. Emma, chatty once again, even strikes up idle conversation with Asha. But after a minute of eager squeezing you just can't help yourself. With short swings you deliver a few weighty spanks down onto this beautiful bum. Asha shouts in surprise and both of the girls share a laugh at the loud strikes that seem to echo off the walls like thunder complimenting the rain. You massage and soothe her cheeks a little between strikes, thoroughly enjoying her soft girlish posterior. But as you get into it and spank even harder Asha suddenly feels the need to escape.
After some rocking and wiggling she manages to twist beneath your legs, turning herself over to face the ceiling. Her shirt works it's way down her arms a little, the shift obscuring her face and forcing her arms up since her head is still trapped in the shirt. At first she flops her arms above her for comedic effect, but when Emma winds up and smacks her cousin's exposed nipple with reckless delight Asha squeals and tries to cover herself. Emma fights back, pushing against flailing arms and pressing against the shirt to continue slapping her friend's bare chest. You lean forward to help your sister out only for your cock to nuzzle it's way up against Asha's squishy little vulva, spreading more precum, only this time across the top edge of her slit.
Feeling something poke her privates she quickly bucks and writhes as best she can. Her movements are so limited with your weight against her legs, but she can still arch her back and push her pelvis up at least a little. It's not really helpful of course, assuming she's trying to find space for herself. Bucking up into you only causes your slick glans to slide between her lips and push against her folds.
One thing that her bucking and flailing manages to do is free her head from her shirt. But with Emma pushing back on Asha's arms, it just so happens that the shirt stays locked around Asha's upper arms with only her head popping forward. The shirt stretched between her arms behind her head only further helps pin her arms up above her. Emma takes advantage of that too, smacking her friend's face again with unbridled joy, cackling gleefully.
Trying to lean into Asha some more, you reach up to tickle her exposed armpits and vulnerable neck. You press down onto her and dig your cock into her crotch, pressing against her sex. Asha yelps once more and begins fiercely struggling, trying to escape.
