As your hand rests on your junk you begin to feel an increasing sensitivity from your dick, moving your hand to cup your balls you rub more of the deposit into your nuts and feel your small cut cock begin to stiffen against the fabric of the boxers. A slight moan escapes your lips as you harden to your full four inches, the head of your cock pulsing and beginning to moisten. God you had no idea boxers were this much of a turn on!
You are completely unaware that the head of your cock is becoming slowly encased in a thick foreskin, its sensitivity is increasing more and more as it reverts to an uncut state. Your hand is now squeezing the top of your shaft and for the first time you feel your new foreskin retract and slide over the deep purple head beneath. A gasp escapes you as this slick new head is exposed and rubs along the inside of the boxers picking up the sweat ground into the fabric. A new smell now begins to waft up from your sweaty junk, heightened by the pulsing warmth of the floor your crotch has taken on a muskier, more fetid stench, as if you haven't washed the head of your dick in a week. The smell hits you hard and you lean back against the floor but instead of turning your stomach you accept it as the price of having a thick heavy cock, always dripping with precum.
Wait, thick heavy cock? You stop rubbing at your dick and actually pay attention to what you're feeling. Your cock IS thicker! In fact its three times as thick feeling almost like a beer can in your hands and the head is soaked in pre, slopping as you jerk yourself off through the boxers. Your other hand moves around the base of your cock as you stare down at the heavier bulge in your boxers and brushes against a pair of balls that have swollen to the size of oranges and are actually pulsing at your touch! You feel so confused, like you should be freaking out but the waves of pleasure coming from your thick stumpy dick are combining with the hot smell of unwashed cock to completely confuse you...
