My girlfriend had a very lewd older sister at her house. The big-breasted older sister, Mao Kurata. She approached me with a smile and gently touched my dick so that her younger sister (my girlfriend) wouldn't notice. Maybe because I couldn't make a sound, she teased me very slowly, with an exquisite feathery touch that was just barely touching it. Without using much pressure, she slowly gave me pleasure with the tips of her fingers, toes, and the tip of her tongue. I'd never felt such pleasure before!
