I loved having sex when my wife was pregnant, mainly cause I didn’t need to pull out (what got us knocked up 
)
But her sexy pregnant belly, especially when she just started showing, offt done it for me…
Then a bit of a lull, until we fucked in her 3rd trimester, 24 hours later water broke, 1 week later the kid arrived 6 weeks early 
.
But she’s 3 in a couple months now, all good.
I don’t have a pregnancy fetish, just my wife who I lust after anyway while pregnant just done it for me…
