It was a hot summer's day and my friend and I were at the gym again. We were determined to keep up our exercise routine and give it our best shot. My friend wasn't necessarily the most athletic guy, rather a bit chubby, but that never bothered me. I still found him attractive and his company kept me motivated.

I could already see some success in myself during the training. I had improved more and more and was proud of my progress. My friend, on the other hand, wasn't seeing visible results as quickly and that frustrated him quite a bit. He was depressed and I couldn't bear to see him like that. After all, he was a good friend and I wanted to cheer him up.

Suddenly an idea came to me and I pulled him by the hand into the toilet. He looked at me confused and asked what I was doing. I just grinned and said: "You'll see in a minute." Then I started to touch him and pulled his pants down. His cock was already hard and I could see how big and horny it looked.

I couldn't hold back any longer and started to suck him. I took him deep into my mouth and moved my head up and down faster and faster. His excitement grew and I became hornier and hornier too. I felt my wet pussy start to pulsate and I wanted nothing more than to feel his cock inside me.

I pulled my pants down too and sat on his lap. His huge cock filled me up completely and it almost hurt. But the pain was so hot and I couldn't get enough of him. He grabbed me firmly by the hips and pushed deeper and deeper into me. His movements became faster and harder until I lost control.

I came so hard that my knees were shaking and I could feel his cock pulsating inside me. I had to break my edge for this incredible dick. I squirted on his cock and he came inside me shortly after. His warm cum leaked out of me while he was still inside me.

After we both came, we carried on with the training as if nothing had happened. My friend seemed fully motivated again and I had the feeling that he had finally forgotten his frustration.

We remained just normal friends and I don't think anything like that will ever happen again. But that one moment was indescribable and I will never forget it.
