Choose a spell at random

Not sure what else to do, you flip to a random page in the book. Without even looking at the margins, you begin reading. As you speak the words on the page, you don't notice anything in particular for the first few lines, but then you feel the dick in your vagina thickening. You stop the spell, turn the page and try again.

This time, as you read, you again don't feel anything. The dick thrusting into and out of your displaced pussy is quickening in pace. You keep reading, more in earnest now. You still don't notice anything unusual.

The thrusts become erratic now; you can tell James is close to cumming, but you're also close to finishing the spell. You speed up your reading, getting to the final line quickly. You finish the spell, and still fail to notice anything different.

You look at the margins as you feel James thrusts deep into your disembodied cunt, ready to blow his wad. The margin simply reads "LOTS and LOTS of cum!" Shit.

You suddenly feel a hot jet spraying into you. It's spraying hard and deep; you feel it penetrating your cervix and flowing directly into your womb. After a full second the spraying stops for a moment, then a second jet flows into you, just as hard as the first. Again, you feel it flow into your womb, filling it. A third jet follows, and your womb feels like it's starting to expand to accommodate all of the semen now inside of you. A fourth jet, then fifth, sixth. You look down and notice your belly distending slightly around your belly. Seven, Eight, Nine, you lose count. Before James finishes cumming, a full minute and a half later, you look 4 or 5 months pregnant with all of the baby batter he deposited into your womb.
