Wow! It's wonderful to see how something so simple can be so erotic.
The movements and expressions are very realistic. Ditto for the jiggling and the sounds.
I haven't seen a single Adult game with medals since a long time, so you definitely didn't go overboard with that.
Only two areas to improve on:
1) It lags a lot - even on low quality.
2) It's way too short. You could add a few more positions. Maybe add a little girl-on-girl action too.
The finger in the butt is the icing on the cake, I really enjoyed that.
I hope to see many more like this in the near future.
Cheers!
