The next morning as we were sleeping naked. My body had a natural reaction and my little brother became big and was poking Lucy's stomach. Lucy opened her eyes and looked at the thing that was poking her and she blushed seeing it. Then she looked at me sleeping and then had a playful expression and she thought, it seems I need to help him. Then she began to give me a blowjob while in my dreams I was dreaming some beautiful lady was helping with my erection. After some time I felt I had reached the limit, so I released it all. It felt so real, while Lucy drank all my semen. Then as I woke up, I saw no one around me. I thought Lucy might have gone for a bath.
