My eyes were apparently locked on his bulge and I couldn't take my eyes of him, he saw this as a green light and he took his cock out infront of me an... i think I uttered a gasp at his size, he was very thick and very long.I was absolutely hypnotised by his erection, I did not think myself gay, and was amazed at how turned on I was and how erotic I found his pleasure in being watched and my own in watching.Mesmerised, I watched him pulling his foreskin back to expose a huge swollen helmet, i. .. having a wank!! He panicked a bit, covered his cock n balls with his hands, but still enough on show to get me excited too!! I just laughed and told him to carry on as i did the same when alone. He didnt know what to do, so i sat opposite him and started to slow wank my now hard cock, whilst looking at him and his cock. After a few minutes he calmed down, and started to toss off too, while stareing back at me. We continued this for a while, then he stood up, walked to my side, and sat next. They had never spoken of that night since it happened, and you could cut the air with a knife it was so tense. Both wanted each other. Both knew it. But neither could start anything, even a conversation about it. Finally, Amy was bold enough to do something. Her skirt was inching up her thighs and she caught her brother looking. She parted her legs some more, exposing white panties with a pink design. He looked up at her and saw her looking at him mischievously. Seeing those pale thighs on. She placed the cup on the table and told me that am still wet and came near me with another towel and started drying my body with it. Then her hands went to my lower part of the body .She told me that I am still wet and asked me to change my Bermudas. My lower part was so wet that she could see my Big Boss bulged out. I saw her looking at them lustfully. But I didn’t show her that I was watching her. Then she gave me a Bermuda and ask me to change it. I rolled the towel around my waist and took.
