idk about a suction toy specifically but a Fleshlight obviously would work & I have tried the Tenga products (their eggs) available on Amazon.com for a six pack it's like $36 and you can actually wash with warm water & re-use them! They feel amazing although you have to do the work, and get some good water based lube as well. I LOVE cumming in the eggs, it's almost better than sex in a way because I can use my own pace and I always blow a huge load and my toes curl! They also have some regular suction type products but they are use-once products btw.
