In The Bank Manager's Cupboard - Part Twenty-one Karin was not long returning to the bedroom, she promptly unlocked his room and breezed in cheerfully, waving her keys as if to promise unlocking him. She pushed David back onto his bed. She stepped out of her panties and climbed astride his face saying, "I'm very sticky, clean up the mess." With both hands she held her vaginal lips open, and tensing her muscles she positioned herself just above his mouth. She ordered, "Tongue." He licked out her vagina, nearly gagging as he was forced to swallow male semen from her recent encounter. Karin taunted David, "If you were a real man, you would be allowed to do it, not just clean up after." She reached down and grabbed both his ears, then wiped herself back and forth over his tongue. Commenting, "As a flannel excellent, as a man useless." She climbed off and ordered David to turn over. Picking up her keys from where they had fallen to the floor she unlocked him and unstrapped him completely. She rolled him onto his back again and once again sat astride his face, this time facing his feet. "This is known as Queening," she said as she let her weight fall upon his face, her anus on his mouth. "I think you can understand why!" David, feeling totally subjugated, could understand that! Karin ordered. "Worship me, that's a good little flannel, and I'll give you your reward." David, now familiar with how to worship Karin, pushed his tongue deeply where it had been before, just as he had in the afternoon. As he did so he felt her touching his penis lightly. Her fingers playing with him like a pianist tripping lightly over a piano keyboard. This in itself a frustrating kind of pleasure, and he thrust his hips up to meet her hands. Trying to gain fulfilment. Karin relaxed back onto his face, and let David do all the work. He could barely reach her fingers, yet he constantly thrust upwards gaining so little for so much effort. Karin almost laughed at the idea, he was being made to tease himself. He was brought to the verge of orgasm, and then she slapped his prick back and forth, painfully stemming his eruption. She repeated the process again and again and David thrust his tongue desperately into her, hoping that it would earn him the ultimate reward. His penis became red and sore, just as his buttocks had been that afternoon. Denying him any release, she climbed off and instructed, "Cold water, and then bed. Behave yourself." David couldn't see her amusement as she locked the door on him. His light went out seconds later. David lay there in sexual torment, his organ pumping, he desperately wanted to touch it. But dare he? Eventually he took the risk of wanking, thinking that Karin must have gone to sleep. He was instantly on the verge of orgasm, but the light came back on. Realising that Karin was almost certainly now watching him he went over to the bidet and splashed himself with water, until his erection eventually subsided. As he returned to the bed, the speaker announced, "That's a good boy, now don't ruin it, behave yourself." The light went out again and David lay down and tried to sleep. He tossed and turned restlessly. Then he felt something silky against his face and he realised that Karin had left her panties in his bed. David held the silky garment up to his face. He inhaled, and by the scent alone his nose located the gusset. There he found the smell of her sex, and he sniffed, like an animal in heat. The scent of her was more than he could take, and he took hold of his throbbing erection, and started wanking furiously.
