In a dimly lit, private space, two muscular jocks engage in a intense session of CBT, their focus solely on each other's bulging balls. One by one, they carefully attach weights, feeling the pull and stretch, their cocks hardening with each increment. They stroke their meat, the tension building as they edge closer to the point of no return. The weights swing and tug, their balls red and swollen, as they grunt and groan, pushing through the pain for the ultimate reward.
