I’ve been searching for years, looking for a doujin about a guy who has a crush on girl who makes sex toys. If I’m remembering correctly, she tests some of them out on the guy and at some point they both try out to toys at the same time that were linked together which then led to them doing the deed. Any help you can offer would be appreciated if you are unable to share the sauce outright.
