How to bounce?

Hey lovely ladies! I have a HUGE FAVOR TO ASK. I have been dating my SO and we just joined the sexually active group a few months ago. Nothing turns on my boyfriend like me taking control, and I know how crazy he would go if I learned to be the one on top of him during sex, bouncing away. One problem, and I know I'm probably over complicating it, but how does one do this? Do you guys have any good tricks or tips for being on top and using your hips to bounce on him? - Future Human Trampoline
