Kiera eats your ass

You jolt when you feel your sister's tongue prod against your asshole, but somehow a little smile appears on your face, even without you realizing. You clench your ass, and then you feel Kiera's hand in your hair, stroking it softly.

"Shh," your sister says. "I've got you." Her tongue is running all around your asshole, still not actually penetrating. You reach back behind you and bury your hand in your sister's hair, pulling her closer. Having your big sister eating your ass is something strange, but the pleasure washing you is more than worth it. Little groans and grunts escape your mouth as her tongue presses against your anus.

Your eyes are still locked on Emily. Jordan has moved on from fingering. Like your sister is doing with you, Jordan is now eating Emily out, though it looks like she's focusing on your best friend's pussy. Jordan's long, pale fingers are hooked into the side of Emily's mouth so that she can taste the wetness of her own pussy as Jordan enjoys it firsthand.

Kiera realizes you're distracted and takes the opportunity. Just then, her tongue pushes past your asshole and enters your ass. Your back straightens and you stretch, almost presenting your chest to the watching Emily and Jordan. You laugh a little, completely involuntarily, and you feel yourself on the brink of orgasm.

"Oh my God!" you blurt. "Oh my God, Kiera, don't stop!" Your grip on her hair gets even tighter and you can feel your sister giggle as she eats your ass.
