Mum and step-dad told us it's shower time. I wash myself then my step-brother. All the soap and me cleaning him makes him get hard. I rinse the water off and get on my knees. I lick his balls and work my way up to his dick. I start sucking his dick good teasing a little. Spitting and making it sloppy. Don't worry mum and step-dad won't know. I keep going until he can't take it anymore and blows all over my face and body! I love to play with it before washing it away.
