I’m super late to this conversation, just wanted to let you guys know that it’s super easy to cath your girl and suck it right out of her. I’ve done it many times with a little soft hollow toy or just a regular cath. She can easily be on her back. There’s nothing like a back pressure like sucking out of a glass bottle like I think I saw someone mention. Clearly, I’ve never sucked really hard. Would not recommend. Gentle is the key. It’s super sensual and very yum. Have fun.
