A virgin, my experience with girls equals zero. My sweet, affectionate older sister, noticing this, gently said, "Want me to teach you all sorts of naughty things?" The taboo of learning sex from my real sister mixed with an irresistible thrill. Watching her use fingers and dildos, making lewd blowjob faces—scenes I'd never seen before. My sister's body, which I hadn't seen in a while, now radiated mature allure. Helplessly, my virgin cock became fully erect. My sister stroked it, sucked it, then took it inside. When she whispered, "You can cum inside," I couldn't hold back and erupted deep into her sisterly pussy.
