Just a short story:

My friend - T - and I go for runs together. We’ve been doing so for the last five months or so, and it’s really developed our friendship positively.

The other day, we had agreed to have breakfast after our run. So we started at her place, and I had brought clothes to change.

When we were done with our route, we headed back to her to shower and change. She was first up, and when she came out of the shower, she only had a towel covering her body, as she walked to her bedroom to get dressed. I’m not going to lie - watching her amazing body only covered in a towel, turned me on a bit, and when I locked the bathroom door behind me in her apartment, the sparked fantasy of having her join me actually made my cock hard. But she’s married, and nothing will happen between us. For a second I thought about wanking it off in the shower, but decided on not doing it.

Fast forward: I got out of the shower, and wrapped a towel around me, before heading out to pick up my bag with clothes. When I opened the door, she walked past me - and I saw her looking down at my bulge, which at this time was a semi. She said “damn boy”, looked up at me, smiling, and then continued to kitchen.

This had blood rushing to my dick again, and I could feel it getting harder, so I blushed, picked the bag and quickly went back to bathroom. I lowered the towel, and my cock was fully hard.

I got dressed, spent the next few minutes trying to think about tax returns, to make the erection fall again. When it had dropped enough, I left the bathroom and joined her for breakfast in the kitchen.
