Shit! Just where the towel ended I could see the fat head of my cock idly resting between two hairy balls! Shit! Shit! Tina had been looking straight ...at my cock! I threw the bathrobe on and went to Tina when she called that dinner was ready."Well, I must say it suits you."Suddenly she giggled a little."What?! What?"Terrified I looked down at myself again. Was I exposed again? I couldn't see anything suspicious so I sat down opposite my sister and drew in the smell from the stew in a long. There was no turning back of events now. Her eyes dipped quickly to look at Martin’s crotch. She took a sharp breath seeing the monster spring up free against Martin’s body and slap his stomach after being trapped under the sheets. She simply stood there in silence with her eyes shifting between Martin’s face and his erect enormous cock. Of course she was getting flushed.Martin’s over 8’’ length and phone pole size thickness was proudly waving openly. The shaved pubes was a big help, hiding. Go ahead and say whatever it is?”I took both of her hands, and looked her in those beautiful blue eyes she has, along with her blonde hair, and her facial features. Her nose, how it crinkles when she smiles, her lips turn up in the corners and make the cutest dimples in the whole wide world.“Earth to Richard, what is it, you have to say to me? We both have school to get to ... Oh my god, I have to leave! We’ll talk later, all right?”She got up and started to go, but stopped, came back and gave. So I went out and then I ask Sunita mam “Is she talking about us?” Sunita mam told me “”she already knew about it as she told about us to her before.” I did not say anything more.Slowly within few days she became very frank and talks freely with us. She start to wear tight salwar and kamiz, and sometime even jeans when comes to Sunita mam home for lunch. She started to look more sexy and hot. I stare at her most of the time when she is in front of me. When she wear jeans her thin legs and ass.
