Will your children be around at the time you are cooking the meal? I just thought it might be an idea to dress up and let him watch you cook :) Depends on self confidence though, I think I would be worried of spilling or splattering sauce down myself...not quite what id be aiming for lol
Other ideas...has he ever tried a male stroker? If you plan on the massage and blindfold...you could sneakily move on to using a male toy on him while he cannot see what is going on 9I suggest warming it first, in a bowl, to take some of the "what the hell is that" shock out of the situation and watching him try to work out what this nice new sensation is.
I haven't tried many massage oils but a lovely lady once sent me sliquid serenity as a gift and I simply love it (Plus its in the sale right now) its vanilla but not as you know it really, its sort of, half sweet vanilla but half musky, earthy scent too. so not too cloying or sickly. You could try a massage candle, those will warm up to drizzle on his skin. Also there are some freezable lubes, which could be fun (Evil grin) Run him a bath and help clean him, wash his hair etc.
Maybe offer yourself up to him as his "sex toy" for the night. Letting him choose what he wants. or in the form of writing down things on card and letting him pick 3. Or if blindfolded, secretly record your session and give it to him his phone back with video as a little surprise present later (So long as that kind of thing wont be taken the wrong way.) Tease and denial may be fun too, if you want to be in control. teasing him with mouth, hands, intercourse, words etc then stepping away and making him wait for the next treat. Not knowing when it is coming. Ice, candle wax (Ensure you purchase candles designed for wax play) a feather.
I hope some of this might be useful x
