Schnell und unerwartet wichs in der dusche

Wanted to get a hard-on in the shower so I could trim my pubes better but the porn I was watching got the better of me. I found myself jerking my cock and feeling it swell and stiffen within my grasp. I couldn't stop myself. Feeling my precum drip down my shaft only made me harder. The feeling of jerking off with a hot load of cum is not something I let myself experience often enough.
