My (38M) fiancé (32F) wants to try DVP and we have found a third guy to try this. But she also really wants to try impregnation during DVP as she thinks it'll be so hot and the extras hotness will make me cum harder and make it more likely she gets pregnant faster... which I thought was really hot at first but the logistics seem really tough if the other guy is unprotected. Now I'm feeling quite jealous.

I suggested the other guy wear a condom and only I cum, which she's open to. Has anyone ever tried this? I'm also nervous I won't cum as hard if there's a condom on the other guy even with lube and my impregnation attempt won't be as good. Has anyone ever been in this situation?
