This happened to me a couple of weeks ago. I was at home watching TV, my 18 year old daughter was upstairs and shouts down 'Dad, l am getting in the bath' 'Ok no problem' l reply. A little while later l go to charge my phone but can't find the charger. I can hear my daughter still in the bathroom and decide to look for it in her bedroom, as she is always using it! Anyway, l open her bedroom door and am shocked to see her friend Lucy naked on the bed doing her make up! Lucy is 20 with short black hair about a size 14/16 with a fantastic pair of tits! 'Oh sorry! I didn't know you were here' l say. 'Thats ok' she says and laughs and as she does so she spreads her legs giving me an amazing view of her shaven cunt and looking me straight in the eyes begins to finger herself. Unfortunately l could hear the bath water draining and realised l couldn't take things further as my daughter was out of the bath and could catch us! I gave Lucy a kiss and got out quickly. Unfortunately nothing has happened since, but l wonder how far things might have gone!
