Not sure what level you like to play at - but a few things that come to mind, :

You could tie him and then trace strawberries down his body, teasing him and then feeding them to him.

Or you could have him use strawberries to tease and pleasure you, then dip them into your and then feed them to him.

Or have him do something, then feed them to him for being a good boy when he does it right.

Though rachel is right, and you could just enjoy a quiet night in, cuddle and feed each other strawberries and cream.

Hope this helps, and welcome to the Library
