I will not give any personal details so don’t ask.

It’s half term so my 12yr old daughter would have to be home alone all day this week as her mother and I had to work, but her grandad (her mothers dad) said he would call round every day and check on her. Great I thought, at least a family member to keep an eye on her.

The week started great, but on Wednesday was able to finish early. When I got home it was quiet at first, wondering where everyone was. Then I heard this knocking/moaning coming from upstairs. I was about to shout out but I suddenly realised it was someone having sex. I slowly walk upstairs listening and wondering what’s the hells going on? As I get to the top of stairs I look across the landing and can see in my daughters room. There’s grandad moaning as he is pounding away on my girls bed. At first all I can see is the side of Grandad with 2 skinny legs wrapped around him. I moved to get a better look and could see it’s my daughter. I couldn’t move, OMG Grandad is fucking her and fucking her so good. I mean really fucking the shit outta her. Not going to lie, I got such a hard on watching them fuck. Grandad was talking to her as he pounded her, she was nodding and smiling. I ducked down on the stairs as they changed positions. When I looked back again my girl was on top of Grandad, she was riding so good and fast. OMG she was actually loving it. It sounded like Grandad was saying ‘just let it out, just let it come baby’. Grandad moaned and my girl started moaning as well. My cock was bursting. I took it out started rubbing it in time with them. Grandad went faster and was really fucking her hard and deep. My girl moaned louder and louder, she was cuming so hard. Grandad moaned loudly and then cum hard inside her. I slowly went back downstairs and waited outside for a while. I was soo shocked and horny at the same time. Her moaning was soo hot. Think I really want to fuck my girl. I’m going to try soon. Don’t know how I’m going to do it yet? I will post again if anything else happens.
