An erection is a powerful trick that a penis does when it becomes sexually aroused. Like an elephant's trunk, it can raise up high into the sky. The erection is often used for sexual intercourse and masturbating or even being naked. And teenagers love to get erections, but sometimes, the get an unexpected one in public, and they will try to ignore it.
Ross stared at joy at Julianne's bare midriff as she walked up to the front of the school board. Before long, his penis began to stiffen and relax as it pressed against his jeans. Then he looked down and saw the erection. He took off all of his clothes to give the penis some air. Now, Ross was naked as a seal and lied down on the desk bare and began rubbing the boner with his middle finger. Julianne noticed Ross and became attracted by the session. Finally, the snout of the penis released semen and Ross wiped it off with a towel. Julianne fell in love with Ross and said "Great job masturbating." as I smiled nervously and blushed, and Julianne kissed my bare body.

When a male or female is sexually aroused, they get an erection. For the male, the penis arches up and becomes stiff. For the female, her clitoris, inside her vagina, becomes stiffer.
