Ironcalves has applied gel to her hard muscular calves. Now she is posing them, flexing, making those hard muscle edges appear. She loves to rub her calves together, feeling skin on skin, muscle on muscle. Ironcalves has learned how to stand on her toes with her heels together and pivot, making the muscle show even better. She shows how hard her calves can get going up on tiptoe repeatedly, making her heels pop out, getting those edges as hard as iron. She never seems to tire of flexing. Quickly going up and down she goes, knowing she is going to make someone cum.
