Andy got up and got dressed, saying sorry to Kelly as he passed her. I finished dressing, then sat down on my bed, not lnowing where to start. I could sense tears welling up, but did not want to start crying in front of her. I was not sorry about getting caught, but more be the feeling that I had betrayed Kelly and Mum. The expression on her face upset me so much, she looked stunned.

After what seemed an eternity, Kelly came over and sat on the bed beside me. She turned round and asked if I was Gay. I told her that I was straight, almost all of the time. She then asked how long things had been going on between us. I told her that we had been together about 4 times, and that it was just experimental. 

Kelly said that I looked as if I was enjoying it, I told her it was fum occassionaly, but I preferred sex with a female. She asked how far we had gone, I told her that it was limited to wanking and sucking each other.

As I was telling her what we had done, I could see that her nipples were getting hard. I think she was actually getting turned on by the thought of it. She asked me when we were planning on meeting up again, as she would love to watch the 2 of us together. I told her that Andy had met someone, and that we would not be meeting up for that kind of thing again. She asked how I felt about that, and asked if I would miss it. I told her I would just have to get over it, but so long as I had Mum and her then I could be happy.

Kelly told me that thinking about the 2 of us together, was getting her quite wet. She asked me if I could give her more details. I told her I was going for a quick shower, then I would tell her. I went to the bathroom and turned the shower on, before getting stripped and jumping into it. A few minutes later I was joined by Kelly. As we washed each other my cock got hard and I could see her nipples were very hard.

We got out of the shower and dried each other before we went back to the bedroom. I was about to start telling her about Andy and I when the phone rang. It was our neighbour telling me Katie was ready to come home. We got dressed then went round to collect her. When we got home, Katie wanted to tell us all about her day, so my tale of exprimental sex would have to wait till later

Mum got home just before 5, I had started to get the dinner ready. We sat and had dinner, them Mum took Katie up for her bath before putting her to bed. Kelly and I cleaned up the kitchen so Mum would not have to do it when she came back down.

Mum came down about 6.30, Katie was in bed, and she'd had a shower. We made some coffee, then went to the lounge. Mum asked what we had been doing all day. Kelly said she had been shopping, but had got home earlier than she thought that she would be, and when she got home.. "I need a drink stronger than coffee" she said, and went to pour us all a drink, Mum looked worried, but Kelly said it was nothing too bad, just a little bit of a shock. I looked at her, pleading with my eyes that she did not say anything, but she gave us our drinks, then sat down.

She started by saying to Mum that when she got in she could hear noises coming from the bedroom. I started to go very red at the thought of what she was about to say. She told Mum that she had got to the bedroom door, when she saw me and Andy sucking each others cocks, until we came into each others mouths.

Mum looked at me, it was one of those situations where I just wished that the earth would open up and swallow me. I could tell she did not know what to say. Kelly then told her about the chat we'd had after she caught us. Mum then asked if the 2 of them were not enough for me, I tried to tell her that they were, but the words would not come out. I could feel the tears running down my face. Mum came over and sat beside me, she put her arm round me and told me not to worry about it, as most people of my age had experimented with the same sex a few times.

Kelly then came over and sat beside me, she too put her arm round me, she told me not to worry as they both understood, and they would help me get through this. Kellt then started to kiss me, while she reached down and started to rub my cock through my trousers. She was soon replaced by Mum kissing me, and I saw that Mum was rubbing her pussy under her skirt. 

Kelly too was rubbing her pussy with one hand while she tried to get my hard cock out with the other, soon the two of them managed to  get it out and took turns in sucking my cock, until I shot my cum into Kelly's mouth, who then shared her mouthful of my cum with the 2 of us. I then fingered the 2 of them until they both came. We got dressed again and Mum poured us another drink. Mum then asked if that was not better than being with Andy, I told her it was more fun, but not the same.

Kelly then turned round to the two of us and told us she had something to tell us both. She said that she knew that she had been told not to tell anyone about what the 3 of us got up to, but told us she had been drunk a few weeks back and had confided in one of her friends. We both looked towards her and said that she should not have told anyone, as our arrangement was illegal.

Kelly then told us that she had not said anything until hriend had told her that she had her brother had been having sex since he was 16. She was Kelly's age, her brother a year younger. This got us intrigued. I asked what they were like. Kelly told us they were of mixed race, their mother was Pakistani and their father was British Asian. She told us they were not black, but were blacker than asian if we knew what she meant. We did not, so she showed us a photo of them. They both looked very dark skinned, but both very attractive.

Kelly told us her friend (Camille), was about the same height as her, about the same weight, but her boobs were bigger. Her brother (Carl), was just under 6', slim and Camille said his cock was about 7.5" long, but quite thin. Hearing their descriptions was getting me hard. I could also see that Kelly's and Mum's nipples were now hard. Kelly then asked us if we would like to meet them sometime, as Camille had said she would love to meet us. Mum and I both said yes, so Kelly said she would speak to Camille on Monday at work, and try to arrange something for the next time Katie was away. Mum said that Katie would be away the following weekend.

It was now about 10.30, I was getting slightly drunk, so said I was going to bed. Mum said we would have to sleep in our own beds tonight as Katie was in the house. We finished our drinks, put off the lights and went up. Mum kissed us both before we went to our rooms. 

When we got into the bedroom we both stripped off then jumped into my bed. She asked what I thought of meeting her friend, I told her I was excited at the thought, as I slipped my hard cock into her wet pussy...
