My (38M) wife (32F) now wants to try a MFF threesome with her former Eastern European 28F roommate after an unsuccessful DVP attempt with another male. The other girl recently got dumped, wants a distraction, thinks I'm really hot, and has heard enough of my wife's sex stories (how she squirts over the entire bed, cums 10x each time) and after hearing an audio recording of us fucking and seeing a pic of the mattress completely drenched from squirting, would like to "help" us fuck (sucking my wife's clit while I'm fucking her, sucking me intermittently to make sure I stay rock hard for my wife, holding my wife's hands through our orgasms) but mostly witness my wife squirting as much as she does. She would love to get fucked by me after my wife is done cumming (this is usually after 10 orgasms and after the bed is drenched) and would also like us both to help her learn how to squirt. I tell my wife it's all about our chemistry and not my cock size or skills, but I'm interested in trying with this other girl to see if I can help her squirt too. Finally they both said they'd like me to finish on their faces.

I am new to an MFF and am generally looking for advice to keep the passion hot while not hurting my performance. Basically my wife talked me up majorly and the recording, pics, and my wife's stories speak for themselves but I'm nervous now I won't be able the live up to the hype. I will follow my normal pre-sex protocol (steak 2 hours before, squats, vitamin D, fenugreek, zinc supplements before, etc.) but I'm a bit worried I'll either be off my game or will be thrown off by another, younger naked woman next to my wife, as hot as that sounds. I'm also frankly worried my wife will get jealous, which is why we all agreed I'd only fuck the other girl when my wife is done cumming. They also don't want me to wear a condom as we're all tested with results shared and the new girl is on birth control, but I'm worried that will incite jealousy.

Anyone have any suggestions or recs for how to have an amazing night? Thanks in advance.
