Mount your Sirs leg… Rub yourself back and forth, trying to reach orgasm. He can help you move back and forth, massage & pull you apart during. He can rub your back and arms. I encourage use of “Dirty-Talk” as it will help a lot.
See if you can reach orgasm only with use of his leg. (Maybe anal plug-in before.) Working together to achieve this will bring you closer. It may take a few try’s to get there.
Everyone try this weekend and report back. Please make sure you describe what worked for you and what did not… Good Luck… Be bad!
