Double Penetration

Hi all,

I've been chatting to a guy on grindr who really wants to try DP with me. Him being the bottom and myself and another guy off grindr being the tops. The idea really turns me on and I'm very keen to give it a go. Neither myself or him have done DP before and I've only seen it in porn. Has anyone here done it? What does it feel like? Any tips for both me as a top and for the bottom?

Cheers!
