When I visit my girlfriend’s house, her big-breasted older sister is always sleeping after her night shift as a nurse. She sleeps completely unguarded, her breasts almost spilling out, and I struggle to control myself. One day my girlfriend goes out and leaves me alone with her. Unable to resist, I start fondling those defenseless tits… and she doesn’t wake up at all. The mischief escalates—burying my face, licking, titty-fucking—yet she still doesn’t stir. With free rein over those breasts, I do everything I’ve always wanted to do with them.
