The Shy Roommate and Her Toy

It's late in the evening, and you're sitting on the couch when you hear a soft, rhythmic buzzing sound coming from your roommate Lina's room. Curious, you get up and tiptoe to the slightly ajar door. Through the gap, you see 22-year-old Lina lying on her bed with her legs spread, a black dildo buried deep inside her. Her eyes are closed, her breathing is heavy, and her free hand is kneading her full breasts. She hasn’t noticed you watching her yet.
