train a young lifter that that big cock is a reward for a good workout, make taking that load up his ass so he can absorb the nutrients, protein, testosterone to feed his pumped muscles the end of his workout. soon he's stacked like this hot bodybuilder and it's so natural for him to crave that big meat.
Love that bud, often find a hard muscled man with those big legs and gluts so horned for my big meat, can bang his prostate and drag back over it for hours. those muscle men always coming back for more cock meat.
