MASSIVE thong malfunction at the GYM. Fuck me! Even the straight personal trainers had their eyes STUCK on my THONGED ASS. And all those eyes watching me, well.... you know what happens.... my MUSCLE COCK likes that so he begins to GROW and EXPAND... INFLATE and ENLARGE... longer and harder inside my spandex shorts. FUCK ME! Now I have a massive erection but I'm still doing my workout. Making my MUSCLES bigger and harder for your enjoyment.
