Look at my boner! Look at my erection! Look at my my long hard meat between my BIG QUADS! He is growing LONGER as I do the seated BICEP curls. My MUSCLE COCK likes exercise, so when I exercise he begins to INFLATE just like my MUSCLES. Muscle cock grows fatter and juicier. He extended longer and harder inside his spandex shorts. Yes! Muscle fucking erection! What are you going to do with my big muscle dick now? Which hole will you use to make my muscle dick happier?
