This is the second part of a short series "Brother, sister and friend." I would recommend reading chapter1 before reading this story.
Laura in a matter of an hour or so had changed the relationship between my sister and I forever. I had been instrumental in bringing my sister to an orgasm that had shocked us both. I had not realized, that other than in porn, females really experienced orgasms like that. Laura insisted that Karen admit that the orgasm I had given her was as good as any she had ever had. Much to my amazement neither female had realized that I had had my own powerful orgasm at the same time as my sister. I had been able to clean myself up before returning to the poolside. Karen still seemed shocked by what had happened and Laura was not making things easy for her. I was delighted to see that both girls had remained topless but Karen had replaced her bikini briefs.
"I fully admit that I keep my little brother devoted to me by allowing him to play with my body when it suits me, but I have rarely allowed him to experience me enjoy an orgasm. If he is really helpful I have played with his lovely little body. It is lovely to see him quite unable to control his little cock. Mind you I am not sure that Matt is quite as small as my brother. I think that at the very least you should offer to put suntan cream all over his rather nice body."
"If you are so concerned about Matt maybe you should offer to help out."
"Matt would you like me to cover you with cream or would you rather your big sister did it?"
My god the day was getting better by the minute. Not in my wildest dreams had I imagined the sexy Laura putting her hands on me. The idea of my sister touching me was frighteningly just as arousing. Laura didn't wait for an answer but upped the ante by turning to my sister and adding,
"I can't wait to see what he is packing, I bet you have no idea do you Karen? If you would like a little suntan cream applied Matt why don't you come over here and stand in front of me."
My cock had been interested in what was going on but became a lot more interested and a lot bigger as I approached the seated Laura. I would have liked to adjust my cock because it was tenting my swimming shorts but decided that it would not look cool. Laura took hold of my shorts before turning to my sister and asking,
"Would you like to do the honors or may I?"
Karen looked stunned by the question and it was clear that she was not going to answer. From being firm my cock became fully erect before the goddess in front of me added,
"Oh thank you Karen I was hoping you would let me."
With this she started to pull my shorts down without pulling the front clear of my erection. She kept pulling until my cock was pointing down at a painful angle until it suddenly became free and slapped my stomach hard.
"Oh dear I hope that did not hurt. Here let Laura kiss it better for you. That is very impressive Matt I have seen a number of fully grown men with less where it matters."
My erection was so hard by now that it was nearly rubbing against my stomach. Laura did exactly as she had said and planted little gentle kisses all the way up my cock until her mouth reached the purple head. Her head stayed where it was as her tongue teased the sensitive point where my shaft met my head. The feeling was sensational and my knees threatened to buckle under me. I had not been completely delighted by her comparisons of my cock to fully-grown men and her next didn't start much better.
"There's a good boy I am delighted that you can control your excitement. The last man I did this to exploded within seconds. That was the end of that particular encounter."
It was a good job I had cum in my pants earlier as I am sure otherwise I would have suffered the same fate. Laura held my erection firmly at the base while she licked me like a lollipop. She demanded without words that I kept eye contact with her as she very slowly enveloped the head of my cock with her mouth. Even with her mouth full she managed to smile at me as my eyes widened. I knew I must not break the eye contact that the dominant Laura was maintaining. She didn't keep my cock in her mouth but alternated between swallowing just the head and licking it. Her hand around the base only moved to tighten or loosen her grip. I had only cum minutes earlier but she was somehow reading my body perfectly to keep me close to orgasm without quite getting me there.
"You really are a lucky girl Karen. He has not only got a lovely dick but he knows how to control it. I love that in a man. If he proves able to control himself a little longer I might be tempted to let him fuck me. Watching you two has warmed me up nicely. I need to have my own orgasm but am not sure which of you I want to give it to me. I bet you have never gone down on a female have you Karen? I might let you choose whether I get to fuck your little brother or receive your tongue. If you lick me to my climax that would leave your little brother to fuck you. I am sure that way you will guarantee having a brother who would do almost anything for his big sister, wouldn't it Matt?"
I was loving the way Laura was teasing my sister and she seemed to be opening up possibilities that I had never even dreamed of. I thought it safer not to answer her question, as we all knew the answer anyway. I was very keen to hear my confused sister's response.
"Would you really let my little brother fuck you? That is just - that is just - not right. It is wrong for so many reasons."
"Okay, give me the reasons and I will give you as many good reasons."
"He's my little brother, he is much younger than you and well that is enough isn't it?"
"True he is your brother, but he is not mine and as for age so what. As for good reasons firstly, he has got a lovely cock, secondly he is here right now with his erect cock and thirdly I could do with a good fucking. Finally, if I need a final reason, I rather suspect that your little brother would be delighted to fuck either of us right now, wouldn't you Matt. So is it you or is it me?"
I wasn't sure whether my big sister would be convinced but the gorgeous Laura had certainly convinced me and particularly my cock. I hoped like hell that my sister would not suddenly deciding that she wanted to taste her friends pussy as this seemed the only way I was going to miss out on getting laid. Fortunately she was far too engaged trying to answer Laura's last question. As for Laura she returned to sucking and licking the purple head of my erection.
"I can't, you know I can't - he is my brother. You can't - oh fuck."
The last two words seemed to seal the deal. I was going to get to fuck the gorgeous Laura and I suspected my big sister was going to be there to watch. I wasn't sure whether the second part excited me more than it disturbed me. I did know I would have not complained if Laura had invited every one of her friends to take front row seats.
"Well it looks like you will have to make do with me then Matt. Just a tip for you, if you want to make this a one off event then cum very quickly and leave me high and dry - or more probably high and wet. Now lets go up to your sister's room as her bed will be much more comfortable."
It was unbelievably erotic to follow a completely naked Laura up the stairs. Her ass was perfect and watching it as she climbed the stairs ensured my erection never waned. As she was above me I could see how wet she was between the legs, seeming to lubricate her movement. She was totally dominant when we reached my sister's room. I was flat on my back as she mounted me taking me deep into her warm welcoming pussy with the greatest of ease. I suspect she knew that the position I was in allowed me to physically relax as much as any man could when a goddess is fucking them.
I was able to reach up and find her beautiful erect nipples with both of my hands. I knew I should try and find her clit but the position made this so difficult I concentrated on her boobs. I have never been so happy that I have always loved to edge myself for long periods while masturbating. It is not the same as the position I found myself in but I had learned to control my orgasm and I was determined to fuck the lovely Laura for as long as she wanted and just as important as long as I wanted.
