อยู่บ้านคนเดียวกับพ่อ - ตอน 2

The weekend has started and I was very horny. Since my dad studied medicine I knew how to trick him into getting to touch my dick. I told him that each time I touch my dick it would rise and that he should check if that's normal. He began touching my dick and to his surprise I was right. He told me that there's only one way to relax my big muscle.
