Looking for pegging position tips when both partners get tired easily

My girlfriend and I have been having a lot of fun exploring pegging lately, and it’s become a pretty regular thing for us. The only issue is that her legs sometimes get tired when she’s on top or standing behind for extended sessions, and if I try to take on more of the movement myself, I end up burning out pretty fast too.

We both enjoy longer sessions when we’re in the mood, so I’m curious what positions or setups other couples have found work best when stamina becomes a factor. Ideally something that lets her stay in control but isn’t as physically demanding for either of us. Pillows? Furniture? Positions that don’t involve too much squatting or thrusting?

We’d love to keep the momentum going, just looking for ways to make it more comfortable for both of us without losing the vibe.
