this about my dirty panty fetish.My niece and her daughter live with me and soon after I discovered this fetish I would inspect their panties as we shared a bathroom and a dearly wanted to wrap them around my cock and let my cum explode in them but they would know its me so I settle for the next best thing and took photos off them and then jerk of to these photos and then once I got brave and took one and that evening I told everyone I was going to bed early and loosened my ass with my fucktoy and kept it in and wrapped the panty around went for it and then suddenly my niece came to my room to ask me something.I barely had my hard cock with her panty wrapped around it covered with my duvet before she entered.I was diffucult too keep a straight face as my ass clenched a round my fucktoy and she talked for a while and my cock stayed hard and then even though I barely touched my cock I still drop my load of cum into it.I guess it was the thrill of it being her own panty and she was blisfully unaware about it that made me cum
