Repeating Erections

[minimoya]

The morning bus to school takes about fifteen minutes. There is a part in the last 3 or 4 minutes of the ride, I get a semi-boner every morning. No other point on the ride I get a boner, just then. Luckily, it goes away to being flaccid before I get off the bus. Also, I am fortunate the bus is not crowded and that it is dark in the morning, so people can't see a bulge. Why only at this time?

Um.. this is a hard question. Although I am the same way usually.. is it possibly because there are bumps in the road or something? If there are, maybe thats causing your dick to rub up against the fabric?

There are a loot of cracks in the road.

Some people have dicks sensitive to vibrations and some engines vibrate after having not been run for one nights worth of time. its normal, same thing happens to me too.

[PewterIceFalcon]

That happens to me a lot on a bus

[Stronger]

There could be alot of bumps and that vibration is giving you one

Maybe because when you started to notice you got hard when ever you approached that time.
