Because I was bullied for being a virgin, my sister surprisingly proposed, 'I'll make you a man.' She seriously taught me step by step, but on my first time, I ejaculated as soon as I was slightly stimulated... Even so, my incredibly kind sister gently taught me how to touch and lick. Somehow, after insertion, my sister hadn't had sex in so long that it felt so good she unexpectedly became a nymphomaniac and milked me dry on my first experience... My sister's out-of-control horniness was insane!
