When you have a massive taur body and a small upper body, this means that all the lower parts are relatively huge. An avali taur could hold friends, give back rides, snuggle with giant paws, and more.

Of course, the penis is also located on the lower body, and is huge too. It's great for squishing friends up against, but normally it's always far out of reach of his upper body. So when Aaron found this portal ring fleshlight, it unlocked a whole new level of pleasure. While previously the penis was limited to squishing up against about half the length of his taur belly (or a friend), now it can span the entire length of his small upper body. The penis still feels great brushing against the soft feathers like with the taur belly, but now also gets to feel the mouth licking it, and the upper body feels euphoric getting to hug the massive squishy flesh.

When climaxing, the throbbing pulses of the penis ejecting avali cum are no longer a distant phenomenon happening a meter away, but rather it throbs right in his small upper arms, making it a struggle to hold into the penis lest it wriggle away. The cum that normally splays out into a small area on his belly would now be all over his small upper body. The cum would come blasting out, splattering everywhere uncontrollably, on his chest, on his face, over his shoulders, etc. He will probably have to close his eyes during and after to avoid cum getting in his eyes.

After he finishes, since he can't open his eyes, he will have to navigate to the washroom blind by feeling around. Then he has to make a choice, what to do with his portal penis. If he carries it to the washroom with him, he would be exposing his penis to everyone he walks by, and it's possible he will bump into a friend along the way, accidentally shoving a handheld throbbing avali penis into their face, still dripping with cum. If he instead leaves his penis behind in the room, someone may stumble upon it, think it's a fun new sex toy, and play around with it (while Aaron would be experiencing lots of pleasure a few rooms over).
