Watched Gf [F] suck of a guy [M] through keyhole

This is kind of part 3 on the gf plays truth or dare with me and friends.

So one of the girls told her the direction for the bathroom and as she walked by me cum drops landed on the floor right next to me.
She gave me a smile a slipped one finger through her pussy as she gathered some cum on it and put it in her mouth. Shook her booty and walked out of the room, all of the guys staring at her.
Well the guy who just came into her followed her telling the group that he ist showering as well in the other bathroom.
We continued to play truth or dare where one of the girls seemed to be hitting on me when suddenly one guy asks „wait isn‘t the second bath broken“
I sprung up and walked to the bathroom where my gf was located.
They had big keyhole so I glance through it as the door was locked. I wasn‘t quite surprised to find the guy showering with her.

He ran his fingers all over her tits and body as he squished his dick up and down on her ass cheeks. The were covered in soap which must have turned her in again as she was reaching for his cock as he started fingering her. I felt something grow in my pants and it was wierd watching her like that and being turned on by it. He twitched her nipples while fingerfucking her with the other hand. I think she even came from that. He pressed her against the glass of the shower as his dick slipped up and down untill he stayed down and slapped his tip against her pussy.

He pushed her upper body down as she guided his dick right into her again. He pulled my girls hair back while penetrating her doggystyle. She screamed and he put the water back in to cover her noises but she was louder.
She screamed „fuck yeah harder“, „cum for me“ „cum in me“ „you are so big“ „never felt such a huge dick“. I was embarrassed and turned on at the same time as i continued to watch.

To my surprise they stopped and she tuned around, got on her knees and started blowing him. THe gaging sound were the loudest i‘ve ever heard from her and she was so sloppy as never before. As out of sudden she pulled his dick out, slapped it on her tongue and made him cum on the mouth and her whole face. It dripped down to her boobs and vagina which she just washed of. She gasped „i am going to finger myself with your cum“ and she did just that as he let his dick resting in her mouth. She came hard and they went off the shower after a real shower. I quickly went to the kitchen as she came also towards the kitchen in a bathrobe. „I think D is still in the other bathroom but we get to share a room with him tonight honey, hope you are okay with that.
She kissed me on the lips and i could taste something salty and bitter.

Something was telling me that this is far from over…
