Suck your first cock

Tiffany takes you a few streets over. Most of the guys here are wearing red. Your sister begins approaching them. "Hey there, this one's just learning the ropes... can I interest you in a $1 BJ?"

As you fall to your knees you ask your sister if she has any advice. "Honestly, every dick is different... just open wide and do what they want. The best way to learn is the way I did... by sucking hundreds and hundreds of cocks."

As the first of many finishes in your mouth, you're glad you were never that well endowed - your rock hard stiffy is hidden beneath your skirt.
