Athletic Briefs

Men think that just having athletic underwear will make them more active, be viewed as being more masculine having a sporty appearance. They ignore the boxers and supporters other athletes would tend to prefer, instead going for the briefs they're so used to. They never consider how those articles are made for a different purpose.

As men start wearing the briefs in their daily lives, they feel the changes start to happen. They feel their stances change, their muscles growing toned as they unconsciously spend more time being active outside. They sweat more, their surface populating with fur to draw heat away from their bodies, their ass perking up from its constant use.

They never think about how men seem to pay attention to them more, their figure growing more feminine with wider hips, their fat peach attracting the male gaze. At least, until the itch starts. They feel it in their rear, their thickened lower half constantly playing with the button inside them. Their hole becomes needy, their mind searching for anyway to relieve it, beginning to notice the way other men can't seem to look away from their bottom or keep their hands off it.

The needy feeling finally takes over, forcing the man to finally whore themselves out to another. They let themselves be pinned down in bed, feeling the dominant role taking in the prone view with pleasure, the new bottom letting a submissive nature take over. They revel in the sensation of being penetrated, their body being used, their mind loving every moment of their passivity. They feel a wave of euphoria every time their prostate is hit, sending their thoughts further and further away.

It isn't long before they go around barely wearing anything else, their crack visible over the briefs they allow to slide down, inviting anyone to use them.
