This blow job machine is amazing; it looks cool, it’s ergonomic, and it is easy on my arthritis in my wrists. I used this on my boyfriend, and my arthritic joints thanked me. He got off, and I wasn’t in excruciating pain afterward. The material is easy to clean, and he loves the suction pressure. He said it really feels like a real blow job, so it’s perfect for when I’m not in the mood for that at the moment. It’s easy to use and has a few different settings. Make sure to always use lube, or it may get uncomfortable with any toy you use
