You’re having sex with the girl you’ve been seeing when she starts begging you to cum inside her. “I just have an impregnation fetish I guess, I love feeling filled up.” But she has no idea what she’s getting into. While you might appear human to her, this is only a temporary form for you. You know full well what will happen to her womb if you fill her with your seed, and she's completely unprepared. Not wanting to explain, you let her milk the cum from your cock with her tight pussy as moans - your warm sticky load triggering her waves of pleasure. She slides off your cock to show your semen oozing from her fertile pussy. “Are you staying the night?” You reassure her you’ll be here in the morning, but leave as soon as she turns over. Now that you’ve impregnated her she won’t ever see you again. The next morning she wakes to stomach pains. It’s almost like she can feel something… moving? No. That’s impossible! But her stomach is visibly growing… it’s obvious something is alive inside her, with the unnatural movements and the alien sounds coming from her womb. Suddenly her water breaks and she begins to moan as contractions course through her body. It’s all happening inhumanly fast! She lays back just in time to birth your spawn, pushing multiple alien eggs from her pussy. First half of this vid is a sex scene with impregnation talk, second half is expanding belly/water breaking/egg birthing content. Lots of sound effects for you cumming inside me and my rapidly growing belly!
