I was struck by the realisation that if I had dropped a plumb line from her shoulder blade it would have reached straight down to the floor. Or, putting it another way, if she, in her normal standing posture, had slowly backed toward a wall, her shoulder blades would have been the first part of her to contact it.
Yvonne again opened her mouth as if to speak. Deciding that my examination was at an end, at least for now, I stood up and kissed her. The poor little thing seemed almost to melt in my arms. I lifted her up – she weighed far less than I expected – and put her gently on the bed, then I undressed and joined her.
This little girl turned out to be a complete sexual animal. Until the moment I entered her she was eager but fearful, her body trembling as I lay on my back and positioned her above me. I had intended to penetrate her slowly for fear that my huge throbbing cock would hurt her but as soon as she felt it inside her she came explosively, her entire body shaking so violently that I almost lost my grip of her; then she thrust herself down on me with astonishing strength, driving my cock deep into the farthest recesses of her cunt. This brought her to a second climax, only seconds after the first, with an orgasmic bellow that made me hope all Fran's neighbours were safely at work.
I was not to be outfucked by girl of eighteen. As she relaxed (but only slightly) from her second orgasm, I plunged into her again and again. I pounded faster and faster and incoherent moans of pleasure escaped her as those tilted hips bucked up and down. Suddenly she came again, more dramatically than ever, and this time it seemed she was spent as her body, so tense and excited only a moment before, now became wholly inert. I felt a twinge of disappointment; she would, I thought, miss the show's rapidly approaching climax (i.e., mine). But I underestimated her. As my own thrusts got faster and the end approached, strength returned to her and, gripping me as if her life depended on it, she answered my passion with her own.
We slammed at each other in an animal frenzy of fucking. Then a huge jet of cum gushed into her, and another, and another, as each spasm of my cock strained to extract every last drop of spunk from my balls. When the first blast hit her, her body jerked rigid and her hands underneath me clutched my back fiercely. My African lioness literally roared forth her pleasure, again and again as each spurt exploded.
And then it was all over and she seemed suddenly very small and weak again, lying utterly limp and helpless on top of me. I too was exhausted; what finally prompted me to move was a sensation of wetness on the bed beneath me. When I got out from underneath her and looked at the sheet I saw marks of bright red. She had drawn blood. I had to struggle to the bathroom and find Fran's medicine cabinet for emergency repairs on my back before I could get dressed and return to work.
I had no idea how long her trance would last; judging by the elemental nature of her orgasms, probably some hours. Before leaving, I arranged her comfortably and whispered to her that she should have a shower and leave as soon as she could, but I promised I should be in touch. In the event, Fran and Connie, arriving from work over four hours later, on entering the building bumped into a very pretty black girl just leaving, in whom they recognised all the symptoms: unsteady walk, sparkling eyes, and huge blissed-out smile. With the splendid collegiate spirit I had noticed among my girls, they told her I would shortly be back and invited her to stay. It would have been a good idea, but on this occasion the obedience conferred by FUCK worked against me; I had told Yvonne to leave and that is exactly what she did.
