Colin, a highschool senior with a strange disease

I´m sitting on my PC, indulging in my favorite hobby, masturbating. Since three years now, I jerk off at least three times a day. Once immediately after waking up, sometimes even in school and two or more times in the evening, when the house went silent. The scene currently running on my screen, features two young woman in cheerleader uniforms and a stud, FFM scenes beeing one of my favorites at the moment. A short blonde with small tits is gagging at the impressive cock of the dude, while her black haired friend, with in contrast to her gigantic boobs, is fucking her ass with a big strapon. The big plastic cock stretching her little asshole is a massive turn on, anal beeing one of my greatest kinks for a long time now.

I take a quick look to the side at myself in the mirror of my wardrobe. I´m one of the smallest boys in my class with only 5´5" and even some of the girls are bigger than me. My light brown hair is almost shoulder length and I often look to the ground and hide my face behind my hair, when something makes me uncomfortable or embarrassed. My body is mostly hairless, only a few hairs growing from my chest and in my armpits. I regularly shave my croth and balls, because for once I like the smooth feeling and in addition it makes my 6" cock looking bigger. I´m relatively pale, since I don´t go out often and spend the most of my free time in my room. Last month I turned 18 and I have come to terms with the fact that the chance of my body changing significantly anymore is very small. My arms and legs are very thin and often people meeting me, think I´m younger than I really am. One more than one occasion, I was even mistaken for a girl in one of the saggy black hoddies I prefer to wear. I really wish I would at least grow some face hair, even if my mom says she likes my boyish look and she doesn´t need another man in the house.

Unexpectedly I hear a sound on the corridor next to my room and footsteps seem to come closer. A look at the screen shows it´s hardly five a clock in the morning, normally no one is awake at this time and I can pursue my hobby in peace. In a rush I pull up my pants, click the mouse hastily to close the video on my screen and turn to the door. After a softly knock, the door opens without awaiting an answer and my mom enters my room.

"Hey Colin, why are you awake already? You shouldn´t play videogames at such a time, a young boy needs his sleep." She seems very sleepy and it´s obvious she just woke up. My mom Angela is 39 years old and she is an awesome woman, as her short black lacey nightgown reveals once more to me. Her whole body seems equally tanned, at stark contrast to my pale skin. Her hair is black and only a little bit longer than mine, often tied together in a ponytail. Her impressive 32H tits are almost spilling out of her nightgown and don't really fit her otherwise slim figure, apart from her plump butt, which is also a little wider but well-shaped. She's a little taller than me, even though she doesn't wear high-heeled shoes like she usually does.

"Nothing like that Mom, I just woke up early and decided to do some schoolwork, if I´m awake anyway." I try to distract her from my jerking session and hope she leaves soon. "And I told you I´m not a boy anymore, I´m a man." I remind her for the hundredth time

"Schoolwork?" Mom asks, completely ignoring my latest comment. She lifts an eyebrow and switches between glancing at my visibly stretched shorts and the screen of my computer. "Interesting school work you have these days, wish I would have been tought something like that when I was in highschool." Her blue-grey eyes are very clear now, all sleepiness seems to have gone away. "Well, have fun with your 'school work', but don´t overwork yourself." She really uses air quotes and smiles suspiciously before she turns to leave. "Boys are just boys." She mumbles to herself before she finally closes the door and leaves me alone.

"I´m a man." I protest silently, but I know she couldn´t hear it. She never really takes me seriously and still treats me like a child, a fact my older sister Denise often jokes about. Denise is merely two years older than me, but while she is treated like an adult... It doesn't matter now, so I place the thought away and turn back to my PC.

When I turn around, I see why she reacted in such an awkward way. There is still porn running on my screen! In my haste, I seem to have clicked on one of the random videos on the sidebar instead of minimizing the window and my face blushes deeply red as I see wich type of scene is played. Couldn´t it have been some lesbian porn or something else 'normal' a mom could expect from her teenage son. No, it´s a scene with a young male adult, beeing agressively spitroasted by two well hung milf shemales. It´s title 'My Stepmom and my Stepaunt ravage all my holes until I faint' says it all. Fuck, one of the actresses even looked somewhat like my mom. I'm terribly embarrassed, but at the same time I realize my cock is still rockhard and twitches excited. I have done worse than jerking off while thinking about my mom, no wonder considering her appearance. Normaly I´m not so much into dickgirl porn, even if I find it quite arousing. The thought of beeing turned on by cocks, even if they are attached to beautiful women, makes me fear I could become gay, so I skip these mostly. But today it´s something else and I slip out of my boxers again and continue jerking my cock, this time to the image of the mom-lookalike porn actress fucking her 'stepsons' ass. I feel the built up in my balls and only seconds later I shoot my cum into a nearby paper tissue, just in the moment the actress on screen comes in thick white ropes over the gaping asshole of the young male actor. At the climax of my orgasm, my eyes fixated on her fleshy, 10 inch cock, I suddenly feel a severe pain in my chest. A surprised scream escapes my lips before everything around me goes black and I fall to the ground, ****.
