~Third pov~
Matt was walking downtown
(mAkiNG My DOwNtoWn with mY tEam, jAke's beIng meaNNn)
Until he was stopped by a call
Matt took out his phone, and saw the Tom was calling
Hmm.. he's probably wondering where I am.
He picked up the phone and heard Tom yelling "Found it!!"
"Um? you found what?"

"I found my g-spot!" Tom yelled out cheerily through the phone.

Matt stood there in silence while blushing a bit
"U-Uh congratulations..?"

"Thanks! It was surprisingly easy to fine aaaand I'm still touching it."

"W-What?! You're calling me in the middle of masturbating?!"

"Sorry.. I just got so excited when I found it, I had to tell you right away..
You know I was always scared of touching down there"
Tom sighed
"Hehe, yet now I'm fingering myself, and it doesn't hurt! So fear conquered!"

"T-Tom, maybe you sh-should hang up n-" Matt was cut off by Tom still talking

"And it's so sensitive I wonder what happens if I slowly rub it?-"

There was a silence for a bit
until Matt hear a moan through the phone "h-haaah.!~"

"H-hhh this f-feels so!~—" the Brit panted
"H-Holy shit, Tom I shou-" Matt was cut off again by Tom
"A-AH MATTY!~" Tom moaned out
Matt jerked up "uh, y-y-yes.?!"

"O-Oh god!~ I need- I need..!~"
"What do you need, Tom?"
"A-Ah!!~ I don't know!! I n-need you here..! I need your fingers in me!!~"

Matt walked over by a building and saw that no one was near there and slowly unzipped his pants "hmmm.. Tom, you want me to touch you down there?~"

"Y-YES I WANT YOU T-TO TOUCH ME ALL OVER!~"

Matt bit his lip and started to stroke his cock "holy fuck, Tom.."

"IM GONNA CUM!~" Tom kept moaning louder as he finally came, panting heavily

"Oh my gosh,, t-that felt amazing.
I should do that more often"
Tom completely forgot that Matt was still on the phone after that
"Oh right!"
He picked up the phone and brought up to his ear
"um.. Matty are you there? Matty?
Are you ther-"

"Tom."

Tom jerked up as he heard Matt behind him, getting startled
"What how did- I hOw- You? Where!?"

"I took a shortcut." Matt said that while grabbing both of Tom's arms are pinning them against the head of the bed, this caused Tom to start squirming
"W-What are you d!-" Tom was cut off by Matt
"Shh, relax Tom.. now it's my turn to find your g-spot"
