The Hidden Erotic Allure of muscle expansion

“muscle expansion” ends the day with her naked on a city rooftop as the sun sets. She lies back on a blanket, legs wide to the sky, fucking herself with a suction-cup dildo mounted to the concrete. The skyline behind her, she rides hard, breasts bouncing, moaning into the evening breeze. When she comes in “muscle expansion,” it’s explosive—back arched, toes pointed, a scream carried away by the wind as her pussy pulses around the toy again and again, city lights flickering on below like an audience.
