Stepbrother Mistakes His Stepsister for His Girlfriend and Accidentally Fucks Her! Slut Wanted It…

My name is Lynn, my stepbro Nico is living in our house with his girlfriend and I really like her, she’s kind and fun but I have to admit I’m a little jealous! I hate her when she’s kissing and hugging and touching my stepbro… and I didn’t know why until she borrowed some clothes from her and took a nap at her bed when I was surprised from behind by Nico and didn’t complained when he started fucking my pussy thinking I was her! This could be a serious problem but it feels so good…
