Karen aims for the national championship in track and field. Her coach, claiming to strengthen her muscles, orders her to do squats and air chairs, then tries to take advantage of her when she's exhausted! Despite her body trembling from lactic acid buildup, Karen desperately endures it. However, her large breasts become her downfall as her thigh muscles reach their limit! The coach's glans finally enters Karen's vagina, penetrating 1mm at a time. Unable to hold the line just before merging, the coach's dick starts pistoning deep inside her vagina.
