I woke up at about 10am; the house was quiet. I got up and went to the kitchen to get myself some left-over-pizza and a glass of juice. I wondered where everyone could be. I sat down on the couch and switched the TV on. My mind drifted back to last night as I looked over at the couch Bianca had been lying on. In my mind, I saw her open legs and beautiful tits; my penis immediately reacted to my thoughts and quickly grew semi-erect.
I cleaned my room, watched porn on my pc, masturbated and showered. While I was in the shower, they came back from wherever they had been. The bathroom door opened and my brother came in; I was standing naked in front of the sink.
"My God! You do sleep late." he said as he put some things into the cupboard.
"I had a rough night." I said looking at him. He didn't know that I saw him and Bianca but he'd find out pretty soon.
"Had a wet dream again?" he asked looking up at me with a smile on his face.
"Something like that," I replied. "How about you... how did you sleep?"
"Well, thanks." he said, not giving anything away. He got up and left the bathroom. He wasn't going to tell me anything. I would just have to tell him that I know what happened. I just couldn't understand why he didn't tell me about it; we usually share our secrets with one another.
We spent most of the afternoon relaxing in the pool. Bianca was now hotter than ever; I had to force myself not to look at her boobs that were covered by a small bikini top. Lucky for me the water was cold.
My brother was the first one to get out of the pool. He said that he would get everything ready for the barbeque.
I got out and made my way back to the flat. I hopped in under the shower and went back outside feeling fresh again. Bianca said she would see us in a while and went inside. I saw this as my opportunity to ask my brother about last night.
"Listen I want to ask you something, so here it goes." I said taking a deep breath. He just stood there waiting. "What happened last night?" finally came out of my mouth.
He looked at me with a puzzled look, "Last night? What do you mean?" he replied still looking puzzled.
"Oh come on, you know what I'm talking about," I looked straight into his eyes. "I saw you and Bianca on the couch getting it on." I said when he didn't answer me. "I came out of the bathroom, went to the living room and bang, there you were licking her pussy." I went on. "Now do you know what I'm talking about?" I asked.
"I was going to tell you but I didn't know when to do it or how for that matter." He said and looked at the flat. "Bianca and I have been fucking for a while now, we didn't know that you would finish up so quickly and thought why the hell not have a quick go at it." He continued when I didn't say anything.
"Okay, so you've been fucking her for a while now but you chose not to tell me about it." I said and continued when he nodded. "Why didn't you tell me what was going on? I could've gone to a friend's house for the holiday to give you some time alone to fuck as much as you want."
"I didn't tell you because Bianca wants to ask you if you would mind joining the party." He said and saw that he surprised me with that explanation.
"She what?" I asked. I didn't believe him. "Okay, I don't mind you fucking with her but don't fuck with me." I said and waited for an answer.
