Riding my stepbrother's massive member, I nearly conceived as his colossal cock filled me with warm cum. The intense pleasure left me craving more, but the threat of pregnancy loomed.
Almost conception, my stepbrother's massive member almost impregnated me while I rode it. His colossal cock was throbbing with anticipation, and I couldn't resist the urge to straddle it. The sight of his enormous shaft sent a rush of desire coursing through me, and I found myself craving his seed. I rode him hard, my body moving in sync with his, our breaths becoming increasingly ragged. His grip on me grew tighter, his thrusts more forceful, and I could feel the impending climax. The room was filled with the sound of our bodies colliding, the scent of raw desire hanging heavy in the air. And then, with a final, powerful thrust, he filled me with his hot, sticky load. His huge cock left me completely spent, his seed filling me to the brim. It was a close call, but we narrowly avoided conception. But who knows? Maybe next time, I'll be lucky enough to experience the miracle of pregnancy.
