I love to cum in my 13 yr olds clean panties and put them back so she wears them all day without knowing my cum is rubbing against her juicy young cunt all day.
I have also been doing it with my daughter's panties since she was 11 years old. It is much better when she has just worn them since I can smell and lick her fresh wet crotch stains. Sometimes I put them on and wear them all day so I can feel her juices against my balls. I finally came so hard into them. It's so wonderful.
I used to do that all the time with my 12 year olds panties...i never came so hard in my life. She slept in them all night, and in the morning after she went to school i'd smell them and jackoff into them while they where still warm...it was woderful !!
Bet your daughter would love that!
