I feel like it's not done often but I do think penis enlargement/growth is pretty hot. On others, on myself, just in general. Admittedly, I just really enjoy all expansions and transformations. (So if you have one in particular you would like to hear about. I'd love to share fantasy about it!)
Imagine the following, could be me, could be yourself, could be a random person. I spend a majority of my time in an office so my biggest point of reference will be dress pants. This person doesn't even need to have a dick to begin with! (sometimes better if they don't…)
They are just working away taking sips of a brand new energy drink. Each sip sends like a pulse of electricity through their body. At first they just think its the energy drink taking effect and waking them up. After a couple more sips they begin to feel a bit of pressure build between their legs. They soon begin to notice those surges of electricity seem to flow right to a spot between their legs. They shift in their seat and spread their legs lightly.
After a couple more sips they look down to see a tent popping up in their pants. With the sudden boner they know they can't just go to the bathroom to check it out, everyone would see the bulge pressing against their pants. It's also way to present to just be ignored. They might try to press it down. However the light touch forces them to gasp as pleasure shot through their body.
They would try to fight back making their pleasure known as they guide their growing member down their pant leg. Trying to ignore it now, they take a couple more sips of their drink. As the surges travel straight to their dick, they look down to see in real time as it presses harder against their pants and inches further down their leg. The squeezing pressure and shifting of the fabric rubbing their dick causes them to become more flushed and their heart beats faster from the pleasure.
Finishing off their drink sends a final, more powerful surge through them. They could feel every pulse of their dick and with each pulse, feel as it grew larger. The pressure between their leg and the fabric of their pants becoming too much. They could see the seams struggling. Every other second they could hear the snap of the seam tearing just a tiny bit at a time.
Everything finally slows down so they can take inventory. Their pants are ruined. Their dick is now as long as their thighs reaching to about their knees. It's also about as thick as their forearms, certainly needing both hands to fully wrap around it. It is absolutely too large by any normal or logical standards.
Now all they need to do is either wait for it to become flaccid, who knows how long that will take, or make it go flaccid. Maybe a passing coworker is willing to help!
