I want to have sex with my step brother so fucking bad! He's only 17! He's tall and muscular and smart! I sit on his lap when our parents aren't home and I feel him get hard. We share a bathroom and I made sure he caught me naked earlier when I heard him coming down the hallway after I got out of the shower. I quickly bent over and acted like I was rubbing lotion on my legs so he could see my pussy. I heard his footsteps stop and he walked back to his room. I peaked into his room and I didn't see him so I tiptoed in and saw him jacking off in his closet. Omg he made the sexiest grunting noises. I got so wet watching him that I left and had crazy sex with a friend of mine and made him cum in my mouth. I wonder if josh is even into me. I would so fuvk him
