My Friend and His Gay/Bisexual Secret

As I knew the secret of a friend of mine, he was bisexual or even gay (I did not know for sure at that time). I felt it was almost impossible to get the conversation topic to go to sex or male-male contacts without exposing my knowledge about him. So this one time I took all the nerves I got and tried some different things. This story begins in a vacation during a hot summer.  Because we were both a bit geeky, and we both liked computer games my friend invited me for a weekend gaming at his parent’s home. Nobody else was there because his parents were on a vacation trip. My friend’s parents were pretty rich, they had a jacuzzi, a swimming pool and even a sauna in their home. For a while we were playing some computer games in their basement. It was pretty hot in this basement so I decided to take off my shirt. After a few minutes he did the same. After a few more minutes I told my friend it was too hot for pants and asked if he wouldn’t mind if I took them off. He did not, so I took off my pants and threw them into a corner. I was sitting there, in my boxers, on the couch playing games. For some reason my friend did not do the same. I was worried I was pushing it too hard, so I did not try anything else.  We played some more games for about half an hour, when my friend decided we should go for a swim. As I deliberately did not bring any swimming suit, I told him I would like to swim because I was sweating like a pig but forgot my swimming pants. He gave me one of his pants, I tried them on but they didn't fit, as he was a bit thinner than me. He then told me he needed a swim because he was heating up and walked to the pool. I followed him, in my underwear. We both jumped in, chilled in the pool for a few moments and then we got out again. Now your underwear is all wet, he told me. I nodded, while I was drying with a tower. I removed my underwear, but still covered my private area with the towel. While he was drying himself I just looked a bit into his direction. My friend started to remove his swimming pants, but did not cover up his parts. I glanced at his penis, a normal size haired, uncut penis. He looked at me, I looked away and pretended I wasn't really looking. My hearth was bouncing. My friend did not say anything, but casually put on his pants. He asked if I wanted to go into the sauna in a bit, I accepted, so he turned it on. We started to play some computer games again, I was only wearing a towel around my waist, as my underwear was drying. There was some tension in the room while we were playing the games. After some games the sauna was ready, so we went in. I was still wearing the tower around my waist, I unfolded it and gave my friend a little glance of my privates, while we both lay down on the seats. After a few minutes my friend removed his pants, he just lay down without covering his dick. While I faked I had my eyes closed I constantly looked at his dick. I started to get an erection. I 'accidently' moved my tower a bit so he could see my half erect dick. No reaction. Of course for me the tension was pretty high. After 10 minutes or so we exit the sauna and I took a cold shower, folded the towel around my waist then he did the same. We started playing some games again, both dressed in towels.  After a few moments my friend removed his towel and said it was too hot for clothes. I was a bit shocked. I looked at him, and of course glanced at his dick. He did see that, and suddenly asked if I liked what I'd seen. I was shocked even more. My heart was breathing around 200BPM. I nodded a bit, tried to ignore the real question and tried to play the game. He then said, I know you're hot too, remove the towel, and he tried to remove my towel. As I was hard, I still tried to cover it up. He looked at my erect dick and asked if he could touch it and immediately said I could touch his if I'd like.  He did not accept no for an answer as he started to jerk me off. I started to touch his dick as his was still flaccid. Two sweaty boys, sitting on a couch, both with each other’s hard dick in their hand, jerking each other. He then moved his mouth to my dick and started to suck it. Of course I liked it, so after a few minutes I was ready and told him to slow down. I started to suck his dick. This was my first cock sucking experience. My dick started to drip some precum. My friend wanted to suck me more, so he did. We moved onto the ground and moved into sexual position 69. We were both moaning and sucking, sucking and moaning. I was ready to cum, my dick exploded into his mouth. He tried to catch all the semen into his mouth but my load was too big. It dripped all over his lips. As I was still sucking his cock I tasted a bit semen. He started moaning even more and then also shot a big load. As I've never had cum in my mouth I did not like it, so I spit it out. He came all over his own stomach. We cleaned up, went into the sauna again and talked about it for a bit.  In the evening we repeated the jerkoff session again the same goes for next day. However, my friend never did or even tried to make a picture or me or my dick.
