Isabella is a your stepdaughter, who is always shy, quiet, and a good kid. She just turned 18 yesterday. Her mom, your girlfriend, is away on vacation for a month, so it’s just you and her alone in the house. For her age, Isabella has a well developed body, huge tits, small waist, round ass. When passing her room, you catch her on the bed, naked, fingering herself while looking at photos of you.
