nylonheelslover is right. if you grab your cock at the base and squeeze as you bring the skin up and over the head, it feels great. Just like a dry handjob. It is the same concept. It is up to you to show her what feels good. Place one of her feet flat on your belly and pull the skin as far over the head as possible and lay it on her foot. Take her other foot and place her toes on the shaft. Start off really slow so she is not rubbing the pantyhose on the head. As much as I am a pantyhose lover, it doean't feel too good when there is too much friction on the head. Hopefully, you have a patient woman to help and experiment. It is worth the wait. As for the brand, it doesn't matter if the technique is right.
