I'm sure we all have a head full of images we conjure up when having a wank. I have plenty, but my top two at the moment are when my girl was on her hands and knees with her ass up, playing with a vibrator, while I wanked and came on her arsehole and pussy, licked it off, then we kissed deeply with our faces covered in my jizz. The other, just a few days ago, was fucking her doggy style while she reached under and fingered my arse. Absolute bliss, in fact I think I'll have to have a wank right now!
