Wash Day Got Me Hard in My Swimming Trunks

I got no undies left so I had to put on my swimming trunks while I wash my stuff. I was already horny after the gym and feeling the fabric against my cock gave me a great chub which I could see as it rubbed up while I walked around a bit. I gotta admit I saw myself in the mirror and it made my dick twitch so I thought it would be cool if we jerked off together and you watch me flex and bate a bit in my swim shorts before we shoot our loads and stuff my guy x
