Letting Grandson Use My Home

I had my daughter when i was young and she was the same with having her son, around 2 years ago he came to look after my home when i was going out and said to him if he was bored there is a box upstairs if he wanted to have a look through it,he was young only 14 at the time,that evening i checked the box it had porn movies and dirty magazines that my ex left behind and took o the first magazine and opened it to see he had wanked off into it,I let him for nearly 2 year's use my home,many times i found cum stains on my bedding, Monday just gone he came as i was just heading to see his mum i left i got know more than 5 minutes away from home and turned back,I went in quietly and sneaked upstairs and watched him getting ready to jerk off,most of the pages we're stuck together,as he was about to start i spoke asking if he needed a hand,I pretended to be interested in the magazine flicking pages with my hand only inches from his hard dick and with one quick move i grabbed it,he let out a little gasp,I forgot how hard a young man dick can be,each stroke gave him a look of extreme pleasure on his face,he erupted like a volcano going everywhere,so much cum to clean up,when his father came to pick him up he was getting horny again but his lift was here, usually he gets in the car but this time he spoke to his dad through the window and he walked back as his dad drove off, excuse he gave his dad was he wanted to finish watching something,he said we only got 5 minutes before he comes back,soon as i shut the front door he had his dick out and sat on the stairs wanting me to suck it,some might think it's disgusting but i did what he wanted, it was less than a minute he cum in my mouth he was holding my head down hard on his dick,I couldn't take anymore cum it was to much for me and he wasn't stopping it was dripping out the sides,when he finally let up his assault on my gob my mascara was running down my face looked like I'd been crying,he's been sending messages that he wanted to fuck me,I'm not sure we should
