So, honey, I approach you shy and thoughtful - I've been thinking about it for a long time and I think I'm finally ready. Are you glad? We've been talking and discussing over it for months and I think we shouldn't waste any more time. Let's do it now! I mean, we'd have to start trying sometime and trying to get pregnant is such a visceral, natural and sensual act, so fill me up with cum right now and here! I mount atop of you and start riding you silly - give me all that cum, fill and inflate me with your cum! I start riding you more and more vigorously until you finally cum.... Wow, that was hot, but... Fuck, my belly is expanding instantly! Your cum must be magic, because it's making me grow so big and full!
