Fill me up withcock, Denny!” “Okay, you sexy little cunt!” grunted Dennis,grabbing his hot-assed sister by the hips. “Your bi...gbrother’s gonna fuck you like you’ve never been fuckedbefore, girl! Yeah… you’re gonna feel this fuckin’thing all the way up to your fuckin’ throat,sweetheart!” With a mighty heave, Dennis lifted the girl’s hipsup clear off the bed and stuffed a pillow under herperfect little ass. Melissa lay back. The girls still sat there watching. Their big eyes followed every move he made. Jason retrieved a piece of the bread and dunked it in the stew and ate part of it. The girls still had not moved or eaten anything.“Aren’t you hungry?” he asked, finally.“Yes, Master,” both girls breathed in tears.“Why are you not eating then?” he asked.“You have not given permission yet, Master,” April whispered in fear.“Permission?” Jason asked, in confusion. “The food is here, eat. What is this permission?”“We. If you cum then the device will send an electrical pulse through the electrodes on your nipples. Like this." He pushes a button and suddenly your nipples are on fire and every muscle in your body tenses. Just as quickly as it starts it stops. You begin to pant. He pulls out another cart. This one has a box connected to two large dildos covered in bumps. He flips a switch and you watch as they slowly start to move back and forth. As you watch it begins to speed up and the dildos start to rotate.. But as they had a staple diet of tongue or rigid dick they were going to have to go hungry for the moment. Frustrated he turned out of the car park and for the first time that day wound the throttle back against its stop. The front wheel became light as he went up through the gears. He hoped he hadn't scared her as he felt her grab him in an effort to stop herself falling off the back of the bike. He braked hard as the bend came upon them, he felt the V of her crotch pushing into him. His prick.
