 Would you make her pregnant for real?"

>it doesn't take long until the drugs start affecting her
>her arousal prompts her to eat even more than usual, linking eating with sexual pleasure in her mind
>because of the fertility drugs she is in constant heat, yearning to be filled
>with delight you enjoy a month of watching her plumping up even more, bordering on obese at this point and frequently increasing sex, as she tries to extinguish the fire inside her
>you've been using protection all the time, denying her the pleasure of ending her heat
>she is pretty much clinging on your dick at this point
>a moaning mess that begs you to fuck her

>the fat mare is panting deeply
>her front legs lowered, she is partly resting on her plump chest
>her hindlegs are spread in eager anticipation, granting you a free view on her pervertedly fat teats, swinging in sync with her pendulous belly which is hanging low and nearly touching touching the ground
>her soft butt sways gently with each breath, partly covering the big prize: her glistening honeypot, dripping fluids in desperate need, creating a small river of perverted juices running down her teats and along her inner thighs
>every now and then she moans as her winking clit splatters her fluids on the floor behind her
>she is far too aroused to even mind the mess she is creating
>"oohhhh I don't know what is wrong with me, but I need you know! Fill me with your filthy cock!"

>you walk over to her and start to line yourself up with her entrance
>towering above the horny mare, you spread her buttcheecks apart slightly to ease the entrance
>she just turns her head and looks up to you, mouth agape and gasping like a dog in the summer heat, eyes half lidded
>you can feel your member prod her entrance, her juices coating your tip generously and her winking invinting you to fully enter
>you smile and give her a healthy slap on the rear
>she screams, not in pain, through her clenched teeth, her eyes pleading you to stop the teasing

>with a smirk, you grab her as hard as you can above her hips, feeling yourself sinking in her soft flesh
>and with a grunt, you bury yourself completely in her

>"oooaaaAAHH! YES! UHNN"
