My brother and I are 5 years apart, with me being the big sister. I am 23 years old, 5'2", weighing 120 lbs, 34C tits, 34 hips and 24 inch waist. I am a brunette that is waist length. I wear glasses. My brother is 18 years old, 5'7", and weighing 140 lbs. So he is rather skinny in High School plus he played football.
I was asleep one night and a noise woke me up and I looked around to see what the noise was. I could barely make out the other side of the bedroom in the dark where my brother was sleeping on the other twin bed or I thought he was sleeping. I noticed a movement and thought to myself, 'OH WOW! He is jacking off!'
So I cleared my throat loud enough for him to hear, "Ahemmm Ahemmm,"
It scared him so much that he covered himself up with his covers. So I asked him, "What are you doing?"
He said, "Nothing. Nothing."
I told him, "I know what you were doing and if you don't tell me then I am going to tell Daddy."
That scared him so much that he said, "Please, don't tell Daddy."
I said, "Then tell me what you were doing then and I won't say anything."
He said, "You said you knew what I was doing so you tell me."
I told him, "You were jacking off weren't you? And I will not tell Daddy if you show me what you were doing as you jack off."
He said, "I don't think that is a good idea."
I told him, "If no one can hear you then it will be ok."
So he took the covers off and started stroking his cock. I was mesmerized watching him even though I really could not see him very well. Then I got an idea. Wonder if I could get him to come over to my bed where the flare ,at the refinery our Dad was foreman at, was shining in the bedroom on my side of the room.
So I said, "I am having trouble seeing you, so why don't you come over here and lay down and jack off."
He said, "I don't think that is a good idea."
I told him, "If we are quiet then no one will hear us so come on over."
So he walked over to my bed and laid down with his head on the foot of the bed. He started stroking his cock again and I was getting aroused so much that my pussy was soaked. Then another idea popped into my head.
So I asked him, "Have you ever seen a female's titties before?"
