The Best Quality [[PIPIS]] Are Filled With Love by Flangst

Summary
In the back of his mind, he brushed off a bit of information he remembered hearing from another addison years ago that strong emotional connections often lead to larger and more productive pipis.
That was obviously wrong, because he didn’t have feelings for Tenna!
Obviously that giant stupid dick was the whole reason Spamton was in this situation in the first place! And just that. Nothing else.

Summary
Spamton falls. And falls. And falls.
He falls through time and space, finding a certain person in the process. That certain someone makes another deal with him: they will grant any wish of his choosing, just as long as they are able to monitor him as he jumps from timeline to timeline, and universe to universe.
Spamton, terrified and hoping to gain freedom, accepts this deal.
Much to his own detriment.

Summary
Everyone knows the local mailman, the one who lives in the dump (not by the dump). And everyone knows he'd rather stay underground for eternity. It's safer, after all. Why bother?
Once an abandoned CRT washes up in Waterfall, Spamton may or may not have to consider a few things. Surely, this warm feeling in his chest means nothing. And surely, Tenna's dream of surface world fame doesn't involve him.
Spamton has nothing to worry about.
Right?

Summary
This is a collection of NSFW Spamtenna oneshots. Each chapter will be a new story based on headcanons my friend and I have been cooking up. The stories will be of varying lengths, ranging from a M to E rating only. Each story will be summarized and tagged at the beginning; the tags used here are just general, frequently used ones in my Spamtenna fics.
Every chapter stands alone!!
Ch1: Spamton enters Tenna's office with the express intent of annoying him when things take an, arguably, predictable turn.
Ch2: While Spamton is admiring himself in the new wings, an innocent graze along his back awakens a lost erogenous zone.
Ch3: After a particularly absurd episode of Spamton's new favorite show, Tenna's going to need a little motivation to keep running that program. And he is NOT going to be gentle about it. -
