I rearranged myself into a more comfortable position as my heart raced. “Why don’t you spread your legs and touch yourself for me, babe?” The wo...ds came out closer to a whisper than a command.She pushed her knees outward and lewdly exposed the fabric of her panties to my view. The tightness in my pants lurched as I saw that it was a thong, with lace around the edges, and a wonderfully snug fit on her hips. “Touch myself like this, you mean?” She ran her fingers along the line of her panties,. He put a hand on each side of her legs, resting on the bed lifting his bum he was just about to stand when he knelt down again.Raising himself upright but still kneeling he rubbed his cock looking between her legs at the sight in front of him. His other hand was now on her thigh and rubbing in circles, he looked over his shoulder at the door to see if I was there.Both hands now on her thighs, he was stroking her, moving upwards very slowly. I heard him mutter under his breath, FUCK Bev that is. "Your going down to X-ray for a final check-up on your ribs. Then you're coming back here to have them strapped up again before doctor Mortenson comes in to check the plaster on your arm. Then it's time for your dinner." And then what?" I asked fishing for answers.She simply smiled, her poker face giving away absolutely nothing. "It's out of my hands Justin I'm afraid." Fair enough," I said. "So when does your shift finish?" Seven-o-clock, why?" Oh," I smiled, "just curious that's all." By this. Her braces were delayed in being removed because the stupid dentist had broken his leg in a skiing mishap the weekend before her appointment. Her non-existent breasts refused to develop and she had absolutely no need for the silly training bra.To make matters worse, her younger sister Pamela was bragging about how she was going to the football game with Jeff Randall and she was already wearing a bra at the tender young age of 13.She looked in the mirror and saw her hated braces still shining.
