As she is fucking intimately with you. Riding your shaft in a good circling movement. You run your hands on her breast, her belly, her nipples. You want to share your pleasure with her and you use your skimming hands to do so. Addicted to her soft skin you can't stop doing it.

Run your hands over her body as she rides you

Don't stop, love. Move your hips deep around me. I love your body, your breasts, your belly. Your nipples are so hard. I can't stop skimming you with my hands.

As you are fucking intimately with him. Riding his shaft in a good circling movement. You feel his hands running on your breast, your belly, your nipples. He wants to share his pleasure with you and uses his skimming hands to do so. You love it so much that you start moaning for him, encouraging him to go further.
