>>2166001oh my goodness that is a phenomenal image. Not even a footfag, but i'd love to get in between those! So, i'll find one for you as well.
anyway,
Before you start fapping, squeeze the bottom of your shaft and tap and rub your dick against the air or your other hand (pretend you're doing it on her tits/feet/ass. you can continue doing that during the fap at anytime)
When you;re about to finish get naked and go on all fours in your bed. put your head down on your pillow and your ass up in the air. cum on anything you'd like. I like your idea, maybe some panties or socks.
