Mark was an unusual boy. His parents sadly died in a car crash when he was very young. He doesn’t even remember them and was brought up by his single Aunt who quickly notice something different about him. Being a bit quite, Mark spend most of his time in his room, did not really have any friends or played any sports. That he was not like most other boys became even more noticeable when he was in his mid to late teen years. His Aunt had always told him he is special and not abnormal or weird but the rumors about him always got too much to handle and they had to move to a new town and new school once again.

“Hopefully this time things will go better” his Aunt reassured him when they went to meet the new school principal of the school he would be going to after the summer holiday. Like with other school principal meetings, in the previous towns, his Aunt did all the talking and Mark just sat there a bit shy and looking down onto his lap. “I really need more information or a doctor’s recommendation to make these exceptions for Mark” was the reply of the 58 year old female school principal. “All boys go through this phase, I really don’t see why for Mark it is any different?” And at that moment Mark knew what was coming. Not that he’d mind, the school principal was fucking sexy, and he had a hard time keeping up the act that he was sad and troubled. “I’m sorry dear but we really have to show it again, you understand don’t you?” his Aunt asked almost whispering. And with a red and shy look on his face Mark stood up and without any warning dropped his pants. He had no boxers on and folded his hands behind his back while still looking down shy. “Do you now see what the problem is??” his Aunt asked the principal a bit more aggressive. Karen, the principal, was totally flabbergasted and just stared with wide open mouth. She could not keep her eyes of the biggest cock she had ever seen. Hung like a horse was the phrase that came to her mind, literally, and it wasn’t even erect yet! His Aunt lifted his cock with her right hand and the contrast with the size of her mature hand made his young cock look even bigger. “Ofcourse all teenage boys have uncontrollable erections but I think you can imagine the problems it gives Mark when he gets erect!? His pants won’t keep it in or it will be down his leg like a small baseball bat!”. His Aunt was very serious about it to the principal. “I do what I can in the morning but I can’t be with him all the time so when he feels it is getting erect I would like for him to have some escape” I want him to have a normal teenage life and not be ridiculed by the other boys”. Still holding his cock in her hand that hung and dangled in a large curve. Mark felt he was getting aroused by not only his Aunt holding his cock again but also by how the sexy mature principal just could not stop staring at it.

“Okay, okay, I can see what you’re getting at” the principal said while she regained her composure. “you can sit down now” pointing at Mark’s cock. Only Mark did not put his pants back on and still kept quite and shy. If he played this right it might be very rewarding he kept thinking to himself. “What do you mean by escape? What is it that you do in the morning to help him” the principal now asked with a slight tone in her voice that she might just know what his Aunt had meant. “He needs to relieve himself or it just won’t go down once it is hard but he can’t do it like normal boys. I mean, he can, but it will not lead to orgasm. So I help him with his morning wood. It has something to do with his physical erotic feelings being connected to the visual and creative erotic part of his brain. Or so a specialist says” his Aunt explained it like it was the most normal thing in the world because she wants it to be that way for Mark. “Euh…, you mean you help him cum???” the principal asked to be sure. “Yes I do” his Aunt said proudly, “ he needs visual stimulation to orgasm and somehow when he sees me helping him with my hands and mouth it works”. The principal thought she had heard or seen everything in life when it come to teenage boys but this was not even in the same ballpark. Still she somehow believed what she was told and even had to suppress the thought how much fun it could be to help this horse boy cum! And is she seeing this correctly, is he slowly getting erect? His cock that was laying in his lap like a large fresh sausage was now slightly raised from his lap. “So, about this escape than” the principal continued while feeling slightly warm, “Clearly giving him a private room where he can masturbate is not going to help. Would porn not do the trick? I’m sure he has some on his phone” His Aunt replied that she tried that but that it only worked if she was watching the porn with him. Somehow a woman has to be present. “It isn’t easy for me either” his Aunt kept going, “I have no normal social life either. But I don’t blame Mark, he can’t helped it being this large endowed” And both mature ladies stared at his semi hard cock again. “Shit, why did you not say anything dear?” his Aunt said with a kind of a sorry tone in her voice. “He is getting hard” she explained to the principal, “I think we need some time alone”, while she slowly started massaging his cock”

Having gone to the toilet to give Mark and his Aunt some privacy behind her locked office door, the principal thought things over. “Is she really that dimwitted?” Karen thought. I’ve been around teenage boys for long enough now to see that he, besides his abnormal large cock, is just like all the other horny boys and only and always think about one thing. But somehow this horse boy has massaged his Aunt into thinking he is a sad, shy and troubled boy who needs her help. Just so he gets it from her. Still, she is right, the size of his cock can quickly make him an outcast with the rest of the students. And she will not have any of that at her school. It could also put her in lots of troubles if some of the more religious parents found out she late a boy like him sit in the same class as their daughters if they where to find out about his horse like cock. “why am I still revering to it as a horse cock, if even turns me on a bit” she mumbled to herself while straightening her skirt and blouse. She must keep this between her and Mark and his Aunt. With her mind setup she returned to her office. Thinking they would be done by now she walked in for the final conversation only to find his aunt still in front of Mark’s chair, on her knees, in between Mark’s legs, her cup c tits hanging out her blouse with massive erect nipples, her hands massaging his large balls and baseball bat like shaft, kissing and licking the fist large deep red round cock head, her saliva and his pre-cum drooled all over his balls and cock. “Cum for Aunty baby, you know how Aunty likes your hot cum. You’re such a good boy with such a nice cock, you make Aunty really horny, you know that don’t you” Karen heard Mark’s Aunt say which made her think she might not be that dimwitted at all. His erect cock was even larger than she though it would be as she walked over to the two of them. Mark had his head tilted back and his eyes closed from the pleasure his Aunt gave him. “sorry, it takes a little longer than usual” his Aunt said with slurping noises, “probably because of the new strange surroundings”. Yeah, sure, Karen thought to herself. They are just enjoying this way to much to stop and all that went before was an act by the both of them to get her to comply. Even though the size of his cock is very abnormal, it does look really hot and horny to see his mature Aunt work it like a pro. I wonder how much cum he will shoot, Karen thought, when she found herself bending over him and started kissing and licking the apple sized cockhead also. Bend over in her skirt Mark was visually treated to the very nice and hot mature ass of his principle. And seeing and feeling her lips and tongue close to that of his Aunt all over his itching cockhead set things in motion. “Oh, he’s cumming, he’s cumming!” his Aunt spoke out loud and proud while she rubbed with two hands all the way up and down his massive shaft very vigorously as the principal kept tickling his cockhead with her tongue. Mark starting moaning real loud and lifted his teenage ass off the chair as the first very large amount of cum shot all over his mature principal’s face and blouse. “Good boy, good boy, good boy…” his Aunt said thrillingly while she kept rubbing his shaft over the full length with both hands. Karen couldn’t see with all the cum in her eyes and felt at least 2 other large loads splutter all over her hair, face and blouse. “Good boy” his Aunt said one more time as she let his soft going cock slap down into his lap. “OH MY GOD” Karen said, “this is both insane and super hot!” she had blurted it out before she knew it. “Isn’t it just” his Aunt said, “when he gets older he will know his cock is a blessing and not a burden. But till then we have to help him get through his teen-age years and you have seen why I don’t mind doing it, even if it is a bit wrong with being his Aunt”. “No more wrong then being his school principal” Karen replied, “but I think we can keep this between us and give this exceptional young man the happy youthful life he deserves. I think I know how we can give that escape he sometimes will need while he is at school. And I will exempt him from gym with a formal note to the gym teacher”.

“I think that went well, don’t you?” Mark’s Aunt said proudly when they where back in the car returning to the camping where they rented a small camping lodge for the time being. “That was amazing, we never had a one that helped me cum during the first meeting and she is just as hot as you are!” Mark replied with no more acting shy or sad, “And I really like her escape idea”, as he smiled smirkingly to his Aunt. “Now, now, only when strictly needed my Dear, you have me for the casual sexual fun remember, we will see how things go after the summer holiday with your first day at school, lets enjoy the new town and summer first”, as she winked to her young stud with a growing bulge in his pants.
