Pretty much what you expect.

The night went by slowly at first. Alex actually got into the game a bit after about an hour, and was excited when his elven ranger leveled up and got new abilities. Michael was the game master and did an expert job of narrating their surroundings and exploits.

At 2 hours in, Michael broke out some alcohol. The nerdy teens passed around some Rum which they shared willing (and eagerly) with him. Finally, their party made it to a city and made their way to an inn. Michael, a bit tipsy himself, began getting their entire party fantastically drunk, a reality that was not far off in the living room of his family home.

Suddenly, the narration took on a....perverted tone.

"Katalina, drunk on the inn's wine, began reaching into the pants of Drognak, the Half-Orc warrior." Michael began to look intensely at Alex. "I think this part would be more fun if we act it out in person. Alex, can you reach into Jacob.. I mean Drognak's pants?"

Alex sat stunned for a second, his inebriated mind taking a minute to catch up. "Wait what? I'm not going to do that."

Jacob, who was sitting next to Alex then stated while smirking, "You kind of already are."

Alex looked down at his hand and sure enough, it was lightly rubbing Jacob's crotch.

Alex sighed. His slutty tendencies appeared to be on auto-pilot after a decent amount of alcohol. Shrugging, Alex reached his hands into Jacob's pants and began fondling his cock feeling it grow the more his hand danced around it.

Michael continued his narration as Katalina (and by extension Alex) took Jacob's cock out of his pants and began stroking and then sucking it.

"Seeing that Katalina was really getting into it, the rest of the party decided to save her reputation and they all went to their shared room. That night, every party member had a turn inside Katalina. Katalina sucked, fucked, sucked, fucked, and sucked and fucked some more until the morning light."

With that, even the nerds who had originally felt shame at getting aroused by Alex in a costume had had enough alcohol and had seen enough perverted sights that they reached for Alex eagerly.

Michael, not wanting to make a mess of his living room, had a devilish idea and moved the soon to be gangbang to his parent's room. After all, the bed was big and he could always do laundry.

As soon as Alex was in the bedroom, Jacob had already pushed him onto the bed and pulled off his underwear. None of the nerds was willing to break the fantasy, so they left the elven warrior armor on Alex as they gathered around.

The first nerd stepped up to Alex's face and place his short and fat cock up to Alex's lips. Alex wasted no time in parting them and the dick slid home, Alex's mouth stretching to accommodate his girth. As he sucked on the fat cock, he felt lube being applied to his asshole. Shortly after, a long and skinny cock made its way up Alex's rectum and began fucking him in earnest.

Over the next few hours, each boy had a turn in Alex's body, some more than once. They came where they wanted, and none of them seemed bothered by having sloppy seconds, thirds, or even fourths. By morning, Alex's jaw was sore and his boi hole was swollen and felt like it had taken a beating - which it had. Alex had cum covering his face, hair and elven armor. more cum was sprayed across his ass and was still seeping out of his gaping anus, spreading in a pool onto the sheets below. Michael, who had watched the scene all night and recorded every minute of it, then came over to Alex, who was splayed face down on the bed, his ass up in what seemed an offering to whoever wanted to go next. Michael unbelted his pants and pulled his own cock out. Quickly climbing onto Alex, Michael slid his hard prick into Alex's cummy hole. Any resistance that Alex's ass would have had taking a cock had been fucked away hours ago.

Michael pumped for a good 5 minutes before he tensed and shot his own load in the overfilled cum dumpster of an ass that Alex had.

"That was great Alex. All of the guys will remember my time as Game Master as the best they'd ever had. To be honest as well, your cum filled butt felt great wrapped around my cock even with all of the cum you had already taken. I think I have a new fetish!"

With that, Michael pulled his cummy dick out of Alex, slapped him on the ass, and went to clean up in the restroom.

After another hour of recuperation (and one more load being shot into him), Alex was steady enough to get dressed and head home. His walking was a bit impaired as he made his way to the car and drove home.
