Helping Out A Young Man

I work as a cleaner at my grandsons school. The way i look, i do get attention from some students. I went in to clean the boy's toilets and seen someone using the cubicle, All i could see was his shoes at first then his trousers was down at his feet. I knew exactly what this boy was doing yet i still asked if he was ok and heard a low voice back saying nan is that you? I said it was, and didn't expect him to open the cubicle door which he did and was still wanking himself off slowly. I found myself staring at my 15 year old Grandson's cock! He was going to stop, that's when i decided to help him along. I got closer and took over from him i honestly thought he was going to cum right then. This boy was leaking so much precum, it felt like my hand was covered in it. I pulled his foreskin back as far as it would go and held it there and his cock twitched and again and knew at any moment he was going to cum and the third time he orgasmed. I held on feeling his orgasm dying off. When he had nothing left i was able to wash his cum off my hand. I looked back and he was still rock hard i think he would of done it again but i had to clean. I made sure it was clear to leave the toilets and let him go.

The following day i went to clean the toilet and he was waiting, wasn't any point in asking what he wanted i knew. He unzipped and pulled out his already hard cock and i began wanking him off and this time he joined in fucking my hand i was worried he might be heard moaning as that was getting louder so i stopped couldn't let anyone know what is going on. He look disappointed but i wasn't done with him. I sat him down on the toilet and fucked him, he was quickly tensing up i pulled his face in to my tits and let him be as loud as he wanted when he came. I just kept on riding his young cock and nothing will beat that moment i made him ejaculate in my pussy filling me with his baby batter. He looked like one happy young man after. Most evenings he comes by after work and we fuck. I know at some point it will stop.
