I have a Fwb thing going with a guy on my swim team. We often meet up after class to have some fun together. I love oral so this week I suggested we try something new.

We met up for a late night swimming session and made sure we were the only ones who had booked the pool. I was wearing my skin tight blue swim suit, with a blue swim cap and goggles on.

I told him to get in the pool and just relax in the shallow end. He knew he was in for a treat when I grabbed his Speedos and took his already erect dick out. I then took a deep breath and went down.

I held onto his legs to help me stay under water and I took his dick to the back of my throat. We like to play breath play with his dick quite a lot so I know I can hold my breath with his dick in my throat for up to 2.5 mins. 3 mins if I'm lucky. So I worked his dick for as long as I could on one breath before coming back up and taking another big breath in.

'You're so hot, get back down there" he said as he grabbed my head and pushed me back down under the water. I only just had enough time to take a breath in again before I was pushed under and onto his dick again. He started thrusting fast. All I could do was hold my breath and let him fuck my face and then as the thrusting got harder, my throat.

This time I had to tap his leg when I needed air and he let me back up. He kissed me, stuck his thumb in my mouth and rubbed my pussy through my swim suit. I moaned and said "are you ready to cum for me?" As soon as I said that I took another breath in as he pushed my head back under the water.

I knew he was getting close. His thrusting was getting faster and harder. I could feel him at the back of my throat on every thrust. And then he went balls deep in my throat and came. I was hoping to take one more breath before he came but I didn't have time. I just hoped I could hold my breath for long enough to let him cum down my throat. He came a lot, the urge to gag came but I had to surprise it. Gagging under water wouldn't be fun especially have way through taking a load.

When he finished he let go of my head and I came up for air. With a big deep gasp I shot up to the surface. I loved every second of that experience. To thank me he picked me up, placed me at the edge of the pool and put his head between my legs. He went down on me next and after my underwater Deepthroat session I was already so horny. It didn't take me long to cum hard too.
