"Alan?", inquired Nina. "No ... not at all", I stammered. Almost as soon as Iíd finished my sentence, Nina got down from where she was sitting, and proceeded to pull her towel away from her body. She then re-tied the towel round her waist and sat down again. I almost had heart failure when I saw the beauty of her magnificent tits. Needless to say, she was one of the most beautiful women Iíd ever seen in my life, and her breasts were sexy as hell. Almost as soon as I realised what had just happened, my cock began to grow faster and bigger than ever grown before. I was eager to touch Ninaís breasts ... even if it was the last thing I ever did. "You know", piped Katy, after a short silence, "I think youíre right - it is getting quite hot in here". She continued, "I might just lower my towel to my waist as well, if thatís alright by you two". "Fine by me, Katy", said Nina, without delay. "Is that alright by you, Alan?", asked Katy. "What ... ", I said dazed. "Oh yeah; no problem, go ahead", I replied. I watched as one of the most beautiful teenagers I knew, untied her towel from just above her breasts, then lowered it until it was round her waist. As with Nina, she finished the ëprocedureí by re-tying the towel around her hips. By now, I was getting really ëworked-upí by sitting within a very small distance of two topless beauties in a sauna. I decided that I should pinch myself in the side, just to make sure I wasnít dreaming. Luckily for me, I wasnít! In order to attempt to confirm the fact that I wasnít dreaming, I chose to go and have a cold shower, as I was beginning to ëburn upí with the heat and the excitement. As I closed the door of the sauna behind me, I breathed a heavy sigh. I stood under the cool spray of the shower, and I tried to get my heartbeat down to a reasonable level. Unfortunately, it didnít seem to want to slow down at all. Within less than a minute, it was obvious my heart wasnít going to slow down for anyone this afternoon. With this in mind, I decided to go back to the heat of the sauna and the beauty of the two semi-nude young women. Not long after my return to the sauna, Nina started talking again. "You know, this heat is getting beyond a joke for me. I think Iíll go and take a quick shower, if thatís alright by you two", she said. "Thatís okay by me, Nina", stated Katy. "Not a problem with me either", I said. Soon after Nina had gone out the door for a ëquickí shower, Katy started asking me questions. "Well ... what do you think of her, Alan?", asked Katy, anxiously. I couldnít help but to let out a slight laugh at the question Iíd just been asked. Of course, I thought Nina was one of the most beautiful young women Iíd ever seen in my life, but I didnít know what to say to Katy. "She seems alright", I said. "Do you think sheís sexy?", asked Katy. "No comment", I said laughing. "Does that mean you fancy her?", Katy continued to quiz. "Aye, Iíd say so", I retorted rather calmly, with a smile. As Nina walked back into the sauna, she noticed that both Katy and I were smiling. "Whatís wrong?", she asked. "Oh, nothing much", replied Katy, "We were just talking about you behind your back!". "I hope you werenít saying anything bad", said Nina. "Well ... ", I said slowly. All three of us burst into spontaneous laughter. As soon as weíd settled down and Nina had taken her seat beside Katy, it was Nina who broke the tense silence. "This heat is becoming really unbearable. If itís alright by the pair of you, I think Iíll take this blasted towel right off". I couldnít believe what I had just heard. Were my ears playing really cruel tricks on me, or had Nina just said that she wanted to take her towel off?! I decided that my ears werenít playing tricks on me, and that I should allow Nina to do whatever she wanted! As neither Katy or I objected, Nina proceeded to get down from where she was sitting, and removed her towel from around her waist. As soon as she did, I thought I was going to have a major heart attack. As it turned out, I had vastly underestimated the beauty of her body. It was a beauty like nothing Iíd ever seen before in my entire life. I continued to watch her as she folded her towel, placed it reasonably neatly where she had been sitting and sat down on it. By this stage, my penis was increasing in size like never before. This afternoonís ëactivitiesí had already surpassed all of my wildest dreams or fantasies. The atmosphere in the sauna was fast becoming increasingly tense and sexual. For a change, I decided to be the one to break the unbearable silence, "Nina, what are the other staff in here like to work with?". "Oh, not too bad; once you get to know them, you know", she replied. As she finished the sentence, I noticed Katy getting down from the upper ëledgeí. I quickly asked her what she was doing. "I agree with Nina - itís getting very warm sitting up here; Iím taking off my towel, just as she did a couple of minutes ago", she replied. Were my ears trying to deceive me again, or did one of my best female friends just say that she wanted to take off her towel? I again decided to presume they werenít playing tricks on me, and waited for the ëoutcomeí.
