"Oh, you're asking me whether I'm a boy or a girl?"
 
There you were standing in front of that student with the lavender hair and antennae. They had been your childhood friend for years, heck, practically, they were the childhood friend of several classmates at the school. Despite that, you cannot recall much of your time with them. They were always rather tight-lipped about their childhood to the extent that they were pathological liars. Even their gender was up in arms considering their habit of pivoting between being a boy one day, yet wears skirts for school.
 
Grinning widely, they propped themselves on their desk with their legs lying limp like that of a doll's. For a small person of their stature, they had long, curvy legs further compounding the confusion you are currently feeling. To further send you over the edge, they pinched the hems of their skirt and lifted it ever so slightly. Is your childhood friend really doing what you think they are?
 
They notice your hesitation and snicker. "You don't have to be that nervous; after all, we had gone to the pool before, and you saw me in one of my swimsuits."
 
They raised their feminine leg showing off their black stirrups. "Besides I know that you think about me a lot."
 
You try to deny it, but the student with the androgynous face could see the lies slipping off your tongue. Before you even began to process what was happening next, they removed their shoe and placed their socked foot directly on the fly of your pants. Laughing, they flicked their toes in seduction sensing that your "member" was bulging to life.
 
"Well, that says otherwise."
 
You shove their foot off you. Your childhood friend at that point couldn't resist bursting into bouts of laughter. A deep shade of red spread across your cheeks. They spread their legs out now with the skirt hanging between their legs. "I can show you what I'm packing down there, but you'd have to kiss it first."
 
With that, they lifted their skirt all the way revealing their crotch to you. A pale, 13-inch semi-erect cock with lavender pelvic hair. Their testicles hung down like sandbags, but they did start to draw up. Around the head of their cock, foreskin veiled the glans in the style of draperies. They clutched their member between their thumb and index finger lightly rubbing the foreskin. A low moan seeped out from their lips.
 
"What's the matter? Haven't seen the family jewels before?"
 
While admittedly intrigued by the size of your childhood friend's girth, you were nevertheless unsettled by their openness with flashing their junk in your face. You turn to leave, but there was a sudden tug on your wrist. Looking back, your angel-faced friend smiled this time showing off their teeth.
 
"Go on and pucker up, madafaka! ~"
 
They took hold of your head and shoved it towards their foreskin. Taking their right hand, they peeled back their foreskin. Inhaling sharply, the glans of the head opened up to direct your face into it.
 
"Oooo....yes, oh. You are good at this~"
 
Your friend was smaller in comparison to you, and yet, their had to be some muscle on their scrawny body due to holding the back of your head without letting up. You try to scream, but you are drawn deeper into their cock. Your face glued against the walls of their urethra, you attempt to shriek again, but those pleas fall on deaf ears.
 
"Ah, baby, don't be scared," they said, "this way we'll always be together!"
 
The flexible glans works their way up your shoulders and ensnare them. Pre-cum drooled from the sides making it apparent that your childhood friend was enjoying toying with you. They leaned back further in their desk. Your larger frame was proving to be more of a hassle compelling the smaller student to lay back as much as they can. Your torso was the next part of your body to be gobbled down.
 
The more you struggle, the deeper your plummet becomes with the urethral walls tightening around you. With your arms pressed to your sides, there was little way for you to worm yourself the opposite way. You could say that being that deep within your friend's cock reminded you of the time you spent inside your mother's womb. And much like your mother, there was an opening that was opening up for you.
 
Before you, the external urethral orifice was opening up. The inside of it proved to be slimy with bumpy walls. As you were gathering your thoughts, you felt trembling from outside. Your friend shivered in ecstasy now that his glans devoured your pelvis and was slurping your legs in.
 
"Mmm, you were probably the most delicious friend I've had in a long time! Hope you make me feel full in there!"
 
In their lower abdomen and within their bladder, your large body was forced into a fetal position with the walls feeling strange around you. Your friend got up from their desk and quickly managed to slip their skirt back up despite the roundness of their abdomen. "Hope you enjoyed this as much as I did!"
 
**********************PISS ENDING*********************************
 
After a day hanging out with their other friends - and drinking a lot - your friend's bladder was completely full. The most sensitive part of their bladder, their trigone, sent a signal to their brain notifying it that you needed to go. While conversing with their friends, they excused themselves and headed to the restroom.
 
Feeling like they were a girl that day, they go into the women's restroom without much issue. Selecting the middle stall, they opened the door and went inside. With no one around, they slid their skirt down and released their cock. The piece of meat hovered over the toilet seat for a moment before a drizzle of golden urine sprinkled down and plopped into the toilet bowl.
 
"Mmm...yes."
 
Psssssssssss
 
More urine evacuated from their body and rained down into the bowl making an audible sound. "Ah...you feel better coming out than when you went in! ~"
 
The floodgates of the mighty river were now open allowing the water to flush out and fill the toilet bowl. They shivered from the chill urination causes. Tentatively shaking the drips of urine off the head of their cock, they looked down at their work. About three liters of golden piss was in the bowl nearly overflowing.
 
"I must say I find you more adorable like that."
 
Giggling, they triggered the lever with the water rushing in to carry you away. Your childhood friend would forget you come morning.
