1 - Handjob in blowjob.
2- Titfrick.
3- add more clothes (like bikinis or new pants, shirts, hats).
4- Chess game.
5- maybe a cat tail.
6- New types of hair.
7- add new shops (ex:toys, hotdogs, etc).
8- A beach date at the nice smoky landscape and dirty sea of oil.
That's all I have in mind, hope you like it or not, it's all good, keep a good job. XD
