Good son: drop on your knees and wait
From Create Your Own Story
You drop on your knees and wait. You hear the other guy unzip and a huge, hard dick slips through the hole. It has got to be at least 9 inches long. You feel your dick get hard instantly and your mouth is watering.
It is your first time so you are kinda scared, since his cock is so huge.
"Just start licking it a bit," the guy in the other stall says. You reach out and grab it around the shaft. It feels so good to feel the dick of another guy.
You move your head closer until his cock-head is touching your nose holes. You take a big sniff and the masculine aroma is making your whole body hot. Your own dick is completely hard now and you feel like you HAVE to have the huge meat in front of you inside your mouth.
You start to slide your tongue over the head of his dick, taking in every bit of pre-cum that is there and is still coming out. The salty taste is so delicious you need to have more of it. You press his head at your lips while swirling your tongue around his meat. Slowly you take him past your lips and start to suck him off. You bob your head up and down eagerly slurping up every bit of pre-cum that was running down his dick before. Every time you go down on him you take him deeper and deeper into your mouth-pussy. You moan loudly as you eagerly take his huge dick further down your throat.
All of a sudden, and without any warning, you hear a grunt from the other side of the wall and your mouth fills with the sperm from the man in the next stall. You quickly seal your lips around his shaft and try to swallow everything he gives you, but it´s way too much and some of it drops on the floor.
You clean yourself up and wait until you hear the other guy leaving before getting out of the stall yourself. You walk over to the sink and wash your hands before turning around to the door. You just freeze and stand there in shock. Seems like the guy you just blew didn't actually leave, and is still standing there in front of the toilet door. The dick you just took into your mouth belongs to none other than your 67 year old grandfather James.
"Did you like sucking me off?" he says while grinning. "I saw you entering the toilets and just could't resist getting blown by such a cute little bitch. From now on you are my own personal cum-slut. Whenever I want your sweet lips wrapped around my dick, you will be there to do it. Otherwise I will tell your parents what a little cum loving whore you are! Got it?"
The only thing you can do is nod. Your granddad then quickly leaves and you run to school.
