I have no idea what prompted her to speak to me, but it happened, and I’m not complaining. It was Friday, end of the week, and at exactly 3:00 PM,...the bell rang, and there was the usual flurry of activity to and from the lockers. I was looking forward to learning this new trick on my board. I slung by backpack over my shoulder, and I was about to take off when I heard someone call my name. Someone who’s voice I didn’t recognize. “Led!” Yeah, okay, maybe my name has something to do with why. Her pace hadn’t slowed down at all. Firm fingers wrapped around my muzzle and forced me to face her again, then resumed playing with a nipple. Unable to meet her eyes, I stared at her mouth instead. Aching with need that I didn’t understand, I panted and moaned quietly. Red lips curved sensually, parting slightly, and her forked tongue snaked out and licked her lips. Exploring fingers slid down my stomach and reached between my legs.I welcomed them.My entire being was focused on her hand.. At least the little voyeur was quiet. He lay down on his pillows, crossing his arms and turning away from Runt, closing his eyes and trying to get back to sleep. After a few minutes of trying, he sat up again. He was angry, tired and now sporting his own bulge beneath his suit. It was as if his ears were attuned to the sound of the aliens going at it like giant, horny rabbits, he couldn’t block it out. Every low moan or cry of glee jolted him awake, jarring him just as he started to drift out. As soon as he inserted the tip of his cock, however, she moaned loudly, and opened her eyes.“Oh, Rob,” she moaned, and wrapped her legs around him, pulling him in as far as he could go. “Stretch me out!”After just a few pumps, Amber was screaming in pleasure. Rob decided to join her in orgasm - he wasn’t used to having quite this much control over his load, but as soon as the thought crossed his mind, he was able to really let loose, filling his sister’s wet cunt with wave after wave of his.
