Getting to know the man in multiple ways

In the next minutes, Ava told the man about her trip to germany, and claimed some of her friends were back on the dance floor. The noice around them was loud, music and conversations, and he needed to bow his head down to understand her.
Sometimes people passing by accidentaly pushed her against him, she felt his body when pressed against him. A couple of times she felt like some people passing by brushed over her ass,but she couldnt tell if on accident or not.
Then a bigger group came, and befor she could step aside, the man, which introduced himself as Ethan, turned her around and pulled her towards him.
She now was standing pressed against him, his arm was resting around her shoulders. Then she felt something else. Down, by her ass, she felt something hard pressing against her body, right around the height of Ethans-
She turned around to look at him, but he just smiled.
Deciding to have some fun (thats why she came here after all), Ava began slowly moving her ass, grinding against Ethans hard on. In response, one of his hands closed around her waist, and they swayed to the music.
She felt herself getting wet under her skirt, the bulge in Ethans pants seemed pretty big, and a party of her wanted to feel it with her hands, but she knew here was not the place.
