Isabella enters the room

Just as I started to feel the pressure in my balls building and the feeling of my cum racing toward my dick, I heard the door open and looked past my feet to see Isabella turning to look straight at me and a look of shock started building on her face. Almost as if it were in slow motion, I could only watch as my body betrayed me even more and shot a load out of my dick like a cannon. If it didn't go up like 3 feet in the air before hurtling back to earth and splashing across my stomach I would be floored. Isabella's hands flew to her mouth and her eyes got wider than I ever thought they could. Then the world snapped back into normal time as Isabella turned and fled downstairs leaving me with cum dripping off of my dick. I quickly grabbed my towel and wiped my cum off as best as I could. Throwing on a pair of shorts just to cover my half limp dick, I tore down the stairs after her.

"Isabella wait! Can we talk please?"

Instead of finding Isabella though, I ran straight into Riley. Backing up, I looked at her and asked, "Have you seen Isabella?"

"Yeah, she just came through here running like her life was on the line or something. She seemed a little upset too. What happened up there?" Riley asked looking at me.

"Nothing you need to worry about. I just need to talk to her. Thank you." I said before trying to push past her.

"What is that white stuff on your chest? It looks a little like glue or really thick milk." Riley asked before I could get around her. Stopping, I groaned internally as I realized that in my rush I had missed getting all of my cum off of me.

Quickly wiping at it, I turned around and said, "What white stuff?" I was hoping playing dumb might allow me not to have to explain what it really was.

"Nice try. I saw you wipe it off. But you still missed some." She said pointing to the side of my chest. And before I could stop her, she reached out and scooped it onto her finger. Pinching it between her fingers and rubbing it around a little while inspecting it, she glanced up at me. Then she stuck her tongue out and tasted it. Shocked I just stood there and stared as I watched her lick my cum off of her fingers. "So, it isn't glue and it certainly isn't milk. Is this why Isabella was running away?"

"I don't know what you're talking about." I retorted still trying to deny it.

Glancing around, Riley moved in closer and whispered, "I can tell that this is cum. I'm not stupid. So, is this why she ran?"

"Fine, yes. But not the reason you think. She caught me in my room and freaked. There. Happy?"

"Eh. So so."

"Can you please not tell anyone?" I pleaded with her while glancing over my shoulder hoping to end this quickly so I could catch up to my best friend.

"Depends. You do some things for me and nobody has to know." Riley responded with a smug look on her face.

"Fine. We'll talk later." I said before turning to leave.

But just before I took off, Riley said, "By the way, you taste pretty good." With that I took off to find the friend that had caught me jacking off with the thought in my head that I had just been blackmailed by my little sister's friend and she said that my cum tasted good. I wasn't sure this day could get much weirder.
