I have a fantasy of meeting a woman in a quiet place. I drop my jeans and wank for her. Before I cum she hold her knickers open and has me cum into them as she's wearing them . Then simply places them back against her pussy and walks off, when she goes home she can play with my cum with her hubby
My ex at uni was really into this frequently before she leave in the morning she would partly dress wank me into her knickers pull on her jeans and go in for the first lecture of the morning
Been a thing of mine for a while, wife getting out car and lifting skirt & stretching her panties for A guy 'or 2' to soak the front and gusset with a hot load of Cum.
Then treat her to a cocktail at our fav bar with the scent of sperm escaping from beneath her skirt every time she opened them slight ;
