Cum in her again intentionally

You slide in gently and slowly start fucking her, its turning her on but she needs a bit more rough handling to bring herself off so she starts trying to push back on your cock. When she makes herself balls deep you grab her hips and push in as hard as you can then wiggle your hips and she starts to orgasm, and you let her go and slide almost all the way out stopping her orgasm mid oooh. She drives herself back again and you do the same thing again stopping her from cumming. This happens a few times and she begs you to let her cum, you say to her you'd really like to nut in her, its your fantasy. Whilst she thinks about it you drive yourself home starting the orgasm again but you stop it mid ooh again. This happens twice more and she agrees to it. You start riding her like a bitch in heat, shes mewling as wave after wave of orgasm rides through her and then you tell her your doing it. "Yeah Jane take my cum, take my baby you slut" and then you start spraying her, feels like a firehose shooting into her. She orgasms as you call her a slut and then whimpers as she feels surge after surge of your baby batter coat her fertile eggs. "oh oh ooooohh, oh my god that was so good. I cant believe we did that though, what if I get pregnant with your baby?" as she says that you start to cum again, you grab her shoulders to keep her firmly rooted to your cock and then lean down to her ear and whisper "I hope you do have my child, id love to look at your swollen belly and know that I did that not your husband that has the right to your womb, oh yes, id love to suckle on you perky tits when they become gargantuan as they fill with milk." Whilst your telling her all this you continue to spray her insides with your jizz and she can feel it, you finally feel your balls drained and let her go and your cock plops out. Locking the baby what must be at least a half liter of cum inside her very fertile womb. "oh my god, ive never felt so full, how did you manage to cum so much, you've stretched my belly its that full", you smirk and look at her, she's right it looks like shes pregnant from the bump in her abdomen. You tell her that she's always been your fantasy and you would have loved to fuck her on her wedding day, that that dress made her look super sexy. She looks shocked and responds with "if id known what you had in your trousers I might have let you, you could have seen me walk down the aisle knowing I had a belly full of your seed." I kissed her at this.
