My advice to you is spend less than $400 next time. That is an insane amount for sex toys. The most expensive flashlight I have had is $150 the best flashlight was $6. The robotic stuff really doesn't hold a candle to the nuance and control you get from a silicone cock sleeve with no case and it is significantly easier to hide and keep clean. Also make sure you buy a cleaning agent and clean after every use.

On a non-sexual note, call your sister and tell her you love her. When you have toxic parents having siblings who care can mean the world. It can be helpful for both you and her. It might even help her feel seen which can be a game changer when dealing with depression. Wish you the best and I hope you find a way out of that situation sooner than later.
