When blood flows from one head to the other.
I was sitting in my class wearing basketball shorts and got an erection, then my teacher grabbed my penis because she thought it was my phone.

When a male becomes sexually aroused, the penis fills with blood and grows to a much larger size than usual.

The erect penis sticks straight up or forward, and is much harder than it is when flaccid. An erection is very sensitive, and contact with it can cause immense pleasure.

Teenage boys tend to get erections very often and doing so is usually very embarassing in public. Therefore, they will usually make an attempt to hide the unwanted erection.
Eric watched as Kim walked up to the front of the room, her perfect ass shaking back and forth with each step she took. He felt his penis stiffen as it pressed against his black/white checker boxers.

He looked down and saw the bulge appearing in his jeans and pressed his hands down on it, trying to keep it out of sight. But the erection's contact with his jeans only caused it become harder, and he felt it force against his hands.

He struggled to keep it in his pants, but it pushed past his fingers and found its way through Eric's fly, standing up in the fresh air. His jeans and boxers dropped down to his knees as the rod continued to grow.

He gritted his teeth as it rubbed against the bottom of his desk, the head becoming coated with precum. He leaned forward to keep it out of sight, but his dick slid across the surface of the desk, giving him an intense feeling of pleasure.

He was overcome with arousal and began rubbing his cock back and forth against the desk, feeling his orgasm build up with every second. His member felt swollen and heavy as his load built up in the head.

The class gathered around him as he let out a deep moan, and his hard-on released a flow of hot white sperm that splashed against the seat in front of him. His dick bobbed up and down as a few more spurts of jizz shot out, then slumped down into Eric's lap.

He opened his eyes and looked around, embarassed beyond all belief. He stood up slowly, his boxers and jeans dropping onto the floor and placed his hands over his member, then turned to leave for the bathroom.

In 7th grade I got an embarassing erection right as I had to stand up and recite the first 5 amendments in history class. I had to use my thick book to hide my boner as I stood up.

(Slang for hard-on.) 1. A male's most magnificent and majestic display of his virility, when aroused by the sight of a beautiful female or by the thought of sex. 2. The magical transformation of a cock that doubles in size, gets hard as a rock, and stands straight and tall as a soldier at attention. 3. The aroused state of a dick that looks like a huge rocket on a launching pad and feels like a giant stick of dynamite about to explode. 4. Sign to a female who sees or feels it that a male is ready and able to fuck. 5. Opportunity for a guy to show off his magnitude and his potency, when he has one while standing up in front of the class; likely to evoke giggles and blushes from girls, to hide embarrassment at the feelings it arouses.
When she felt my erection as we slow-danced together, she sighed deeply and drew me more tightly to her.
I could feel myself getting an erection as we kissed.
When I saw her standing in her wet bathing suit, I got an erectionso big that my cock stuck out over the top of my trunks. She smiled when she saw it and said, "Looks like somebody's glad to see me!"

1. When a man's penis is enlarged due to natural attraction to another person. Men will normally get a hard one after looking at woman who are posing in a manor that is 'stiffening' to a man. See example. Erections are also obtained during sex when fooling around with the opposite gender. However some teenage boys are unable to control this urge and often get an erection in an embarassing situation. Some men get an erection over another man ; this is the sure sign of being gay.

2. A building that has been created - generally through man made resources.
Description 1 : The man got an erection after looking at a semi-naked woman who was sucking her finger seductively.

Description 2 : The erection of the new school had been completed a day earlier than expected.
