Mommy is having trouble unclipping her bra and asks you to give her a hand. You then noticed how sheer and see through her underwear is. Clearly, you do not mind seeing mommy like this. You can't take your eyes off of mommy's body and she notices you looking at her. Mommy loves you so much and really needs to blow off some steams so maybe you could have a little bit of fun together but remember, this has to stay between the two of you. No one else can find out you jerked your cock whilst watching your mom touch herself.
