Golden oil glistens on every curve in “20cm long” under flickering candlelight. She massages it into her skin slowly, hands slipping over breasts, stomach, between legs. The slick sound mixes with soft moans as fingers plunge deep inside. She rides her hand harder, oil making everything shine. When climax hits in “20cm long,” her back arches dramatically, toes curl, a low cry echoing. “20cm long” feels like an ancient ritual of pure female pleasure.
