I was so focused on the clock on the blackboard in the classroom that I didn’t notice what Brayan was saying to me
“Hey buddy, what the fuck are you thinking? XXX … How did this happen, my breathing was becoming more agitated
“How does it feel” – My sister told me with a shy voice
“Fucking good, don’t stop I’m about to…” I couldn’t hold back any longer, my cock was releasing wave after wave of semen
My sister seemed quite surprised by the amount of semen coming out of me
“I-I’m s-sorry, I s-shouldn’t have. …” – she washed her hand and continued with the bath avoiding going over my crotch, when she finished she helped me get out and put on clean clothes
As quickly as I finished putting on my clothes, she left my room
