The lunch period was just about over, and Pete was bringing his empty lunch tray to the collection window, when a small touch on his arm brought him b...ck to reality. He looked down at the pale, tiny hand, gently touching him on the wrist, and his heart nearly stopped. Ashley Waters stood next him, looking up at his scarred, battered face, those glorious eyes not seeing the road map of pain and misery etched deeply in his skin. Pete swallowed the lump in his throat as he looked down into that. “Eat, drink and be merry,” Samantha said to me. “You need your strength for the competition.” I was alarmed. Had she set me up with the remark about endurance only to tell me now it was about strength? However, she’d told me to do something, so I obediently took a bite of the burger and a swig of juice. Samantha put her arm around me and put her lips to my ear. “Dorothea did not deign to speak to Chris or Zach. You’re doing well, little boy.” My eyebrows flew up. I was OK! Whew! I smiled at. I was no longer a virgin and it was my gorgeous sexy big sister whose pussy I was now pounding. And, she was loving it! Her moans were loud, and her legs were now wrapped around my ass, her hands on my back with her hips thrusting upwards to meet my every stroke. We built up a great rhythm and my cock was getting buried to the hilt inside her wet cunt each time. It was not long when I felt the cramping in my balls signaling the start of my orgasm. I was too far gone to think about the potential. She looked to her left and saw that Terri had her top pulled up and was pulling on her nipples. Terri noticed the movement of her sister and turned her head to look at her. Heather had a hand up under her camisole kneading one of her ample tits. Then she noticed that the other hand was inside her panties, rubbing furiously.She had felt her pussy tingle before, of course, when she had watched some porn with a friend or had really naughty thoughts about someone. And she had rubbed her little nub.
