Play dough is always fun. Great for developing hand strength as well. I usually make my own using the typical flour, salt, oil, water, cream of tarter recipe. There are tons of recipes out there online. I usually let my kids pick the color--and stick to one color at a time. Then I give it to them with some cookie cutters, plastic knives, rolling pins, jar lids, etc.
Arts and crafts of any type. At 2, finger painting (and painting with a brush) are still quite fun. Also, drawing with crayons, pasting stuff, etc. I really like the Kumon workbooks designed for 2 year olds. There's one called Sticker and Paste, I think, which my DD really loved at that age.
If your son doesn't like story time, what about music? Just put on some music you like and dance with him. Or make music with pots and pans, maracas, etc.
There are some Montessori at home type websites that give you ideas of things to do. Spooning things and using tweezers is probably age appropriate. Have two bowls. In one bowl put some uncooked beans or rice and give your child a soup spoon or one of those Chinese soup spoons. Have him spoon the items from one bowl to the other.
You can also do practical life stuff with a child's size pitcher, dustpan and brush, etc. Set up a dish pan filled with warm soapy water on a low table (or having a stool for your child), let him wash his breakfast dishes, etc.
Nursery rhymes... Grand Old Duke of York, Peas Porridge Hot, Humpty Dumpty, etc.
Just play :)
