On the gamescon

Button was walking with Rumble. The area was huge and had enough space for thousands of ponies. He saw a lot of different cosplay, games, comics, TV, manga... it... was... awesome!
Luckily the trooper-costumes had backpacks, so Button could put all the stuff he bought somewhere. Rumble was less lucky, he had to use this empty space on his back for his wings.
Rumble was not interested in merchandise, he was flirting with every mare he saw, female Deadpool, Sailormoon, BikerMares from Mars, X-Pony Mares and more, Rumble went into hunt mode as soon as he saw a pair of nice boobs.

Button just had played the demo of the new Devil May Cry for half an hour and returned to Rumble. He found him with his helmet off, he was deeply kissing with a green mare from Orion, or maybe it was Gamora-Cosplay based on the new movies? She was green and her tongue was deep into Rumble's mouth. Button gulped and he watched them.
Rumble kneaded the green Buttocks as a baker did with fresh dough. Button could see how his fingers went under the mares skirt and swifted through her butt crack, the mare let out small aroused sounds when his strong fingers touched her butt hole. The tip of Rumble's index finger was pressing gently against that warm slightly wet hole, making little circles and pressing the tip inside. Both had to moan at this moment.

Button had to clear his throat, this sight was fascinating, but there was something more important “The presentation will start soon.” he said, his voice was still slightly changed thanks to his helmet.

“Dude!” Rumble pulled his hand back and looked at his friend “I am right in the middle of something!” he seemed some kind of angry.

“We don't have much time, I want to see it from start to beginning!”

“That's okay.” said the mare from Orion “I need to to go to the bathroom anyway, meet me at my room.” She winked at him and walked over to the bathrooms.

“You hear that dude? There is a smoking hot Mare waiting for the D! Let's move on and let's hurry!” Rumble was rubbing his hands to each other and walked very fast.

Button followed him, but then he looked back one more time he saw the mare from Orion and “D-Dude? Look!” Rumble turned around just in time to see that the mare was going into the stallions bathroom “I... I think you just tongue wrestled with a dude, dude.”

Rumble became all pale, he hurried up to put his helmet back on his head “What happens on the Gamescon, stays on the Gamescon, understand!?”
