use your alterations

Held at bay by her foot you start to tease "Oh? my smart perfect wifey doesn't know how protection works?" she blushes "momma just said boys only want one thing, to put their dirty thing in me and get me pregnant" the red of her face seems to run down her body. You grip her foot "well that isn't untrue, though I would prefer to have a few years before I actually impregnate you" she squirms now trying to crawl away but you have her foot so she can't, you realize she is crawling toward where she dropped her wand and you pull on her ankle dragging her hips all the way to yours.

She looks up shocked "Um.. sam?" she nibbles her lip in worry as you tease your cock against her pussy "Yeah Hermonie?" she blushes when you use her name, seeming like she can't turn much darker red "I... I don't want you to use that er... um... protection." you chuckle as she continues "all those... movies you showed me... they don't use condoms and say how bad they are and how much they hurt and I love you..." she closes her eyes in embarrassment as she says that but you can feel her pussy get warm and leak as she says it too.
