It's great fun (erotic, nasty, - all the good stuff)! But there's so few arcades remaining near where we live (Western USA). We (wife and I) learned to check the place out once inside - stand near the entrance to the hallway leading to arcades, or pretend to be shopping the marital aids, - until we had a feel ("feel" - a little play on words....) for who was in the store, attractive, clean, etc. There's some arcades you just don't what to take the risk in. And you also need to hang out and observe - see if the cops are stopping in on a regular basis. Our adult arcade stores were occasionally raided by the cops.
Bring your own tissues, and it's a good idea for both of you to not have underwear on - it just gets in the way. We found that in order to fuck, she had to invite the guy into our booth, and I had to step out. There wasn't enough room for 3. I watched from the next booth, through the gloryhole. It's not real satisfying sex for the wife - guys always cum fast in that scenario. But seconds with her is glorious (although also fast). She'll be ravenous with her need for more sex when you get home, and she'll be reeking with cum aroma from the dried cum on her breasts, cheeks and neck. What more could a husband ask for?
