Wanking over nude pics and a certain video

Hi im 23 and have been in a relationship for 5yrs,my partner and i live together and have done for around 2yrs.she recently started working part time 4 nights of the week, for her mother in the familys care home.starting at 7pm and getting in at 1am.

As we have lived together for yrs and both work days, our routine is wake up have sex then get up,shower, breakfast, kiss and see you tonight,then we get in from work have a shower make tea,do the chores then around 7.30pm either pub till 10.30pm or watch a film or 2 then goto bed around 11.30.We then have sex nearly every night unless its that time of the month and then im gettting blow jobs so we are sexualy active.

However since my partner has starting this night job,im now sat in alone and wondering what to do with myself,i dont go to the pub on my own, so i watch tv then get bored so end up on the computer.I was talking to a lad at work about 2 weeks ago, about how boring it must be for people wo live on there own if there is nothing to do accept watch tv or go on the laptop,he suggested a ps4 so i bought one and no didnt work still bored after an hour.Another lad at work said id love to be on my own at night wanking over porn and filth on the internet and told me a few sites to visit where it hosts girls from where we live.really i said so that night i put in the sites name and clicks the area where i live and sure enough,instantly i see a girl i know from the pub,im like jesus after about 10 minutes ive seen about 10 girls i know.fully naked and batting themselves or being fucked even 3somes.ive still got around 25 pages left to go,when i see on there one of my neigbours, she is 28 gorgeous and always says hiya when she sees me or the mrs, now im looking at her playing with herself, fully naked and theres a video link which is 15 minutes long.after about 10 minutes into the video my cock is throbbing,so i go upstairs take my clothes of put my robe on and come down stairs sit at my computer desk and continue to watch the film,with about a couple of minutes left to go im playing with myself,she finishes herself off and blows a kiss.I then click onto the next girl and the next, whilst still playing with myself and then i see just a video link on 1 page, so i click on this and its a girl, she is being recorded by someone but from the kneck down,she has an awsome body amazing tits and a landing strip of pubic hair which gets me turned on because my mrs dosnt like pubes so shaves,so im watching the video and its 28 minutes long,i feel a tingle like im going to cum so i stop and watch the video some more,this girl gets a black vibrator from under her mattress and sticks it to the floor via a rubber suction pad on the dildo and then sits on it,this dildo is about 14" long and she takes the lot she starts bouncing up and down on it,her perfect tits buncing in rythm huge nipples and im thinking i hope im going to see your face.after about 10 minutes off riding this black cock she gets out a finger vibrator and starts rubbing it on her clit.moaning and rubbing it faster i cant help it im now holding my cock and wanking again, theres now about 5 minutes left to go on the video and i get some tissue and sit down and i start wanking faster, watching this girl doing herself with this finger vibrator im feeling myself about to cum, so i start going faster,im about a minute of cumming when the camera lifts up lifts up and i see its my 20yr old SISTER... but the weird thing is i didnt stop, i carried on wanking till i cum about 30 seconds after seeing it was her.and the amount of cum that came out was amazing,it was gushing out for at least 10 gushes of cum huge amounts as well.i carried on wanking till i thought i was finished,but then i started cumming again once this stopped that was it,but then the video finished shortly afterwards i then saw it was her ex boyfriend, who had been recording her,so had posted it on this site as a revenge thing.

I wanted to tell her but i couldnt bring myself to doing it as she would know id watched it.plus my mrs would get to know ive been watching porn whilst she is at work,so on the page it said complain about this video so i did but nothing has happened its still on there.this is the problem im having,i know its still there as i keep watching it.i cant stop ive got a link on my iphone that takes me straight to the video hidden in a password video vault.ive watched it at least 3 times a day, since i saw it.and i get an erection watching it as well,i dont want to have sex with her or anything,i just cant believe she has a body like she does and can ride a huge black 15" cock to the floorboards and cant believe she let her ex bf record her.im thinking of approaching my sister and telling her someone has told me theres a video of her on the site, so she can then get her ex to remove it.and if he dosnt she will goto the police.its just that her knowing ill have watched it,will she be able to talk to me like she used to, or will she be too embaressed.or do you think she will say thanks for letting me know and nothing will change as we get on really well.i was going to mention it to a mutual friend of ours but then thought, my sister would be angry at me for telling him as he would then have seen it as well.what do you suggest.it needs to be removed as i cant stop watching the video
