Cousin fingered again...not quite as expected!

Yesterday she was on pain killers for something and by evening already appeared quiet chilled. I watched her take her overnight tablets and so I went off for a drink, intending to go check on her in an hour or so.

I went up to bed about 1am, passed her room and i could see the light was on from the 3 inch gap in the door.
I pushed it gently and asked if she was okay, but all I could hear was a feint snoring sound.

I walked to her side to turn out the light and saw she was lying on her side with her right hand resting off the bed with her half smoked joint still hanging from her lips.
I couldn't resist getting my cock out, taking her small hand, wrapping it around my cock and feeling it swell as i made her wank it.
Then i flicked the light off intending to get under the covers with my phone and record some footage of her pussy. Typically the one time I get opportunity and the battery was nearly flat!

Anyway I crept under the covers and managed to catch a few minutes of video as I first exposed and then fingered and gaped her pussy hole, I couldn't resist and had to give it some licking as well.
Then sadly the phone switched off and I made the decision to sneak back out and go fetch my laptop and webcam as it was to good an opportunity to miss.
10 mins later the laptops by the bed, screen covered to hide the light and the webcam is inches from her pussy hole as I licked her some more and gaped her hairy pussy with two fingers,
By this point I was desperate to get my cock up her so slid up the bed behind her and started fumbling around trying to get myself buried in her pussy.

I had two finger in her and ready to guide my cock in when out of the blue she jerks away and says 'what the fuck was I doing'...
I froze and said nothing, hoping she might just go back to sleep, but she asked again before adding I shouldn't be taking advantage of her like that.
I said sorry and that I'd go and then she surprised me again and mumbled I didn't have to go, but that I shouldn't be groping her in her sleep. I replied okay and lay silent and then cuddled her and she went back to snoring in minutes.
I went back to my room and hoped she might not remember today but she did and a discussion followed this afternoon which as proved interesting and thankfully not caused any long term issue so long as I'm not caught with my fingers or mouth in the cookie jar again without permission!
