I mean think about it, sticking your dick while she's got a bun in the oven seems like something only a mad man would do.
I wonder if you could deform the baby by doing that
I mean the baby could be born with a dent in it's skull and shit *checks for dent in skull but finds none*
I mean, anal sex is another option but the feeling of taboo you would get would be crazy. I think you could murder the baby with your money shot (which would probably have a psi of 10000 lol)
