Son, I know you saw me and your brother fucking last night. I'm so embarrassed! I could tell you had a hard cock and you were sad like you wish'd it was you. The reason why I didn't come to you first is your brother is more experienced. Mommy shouldn't be your first! Okay if you're okay with it... I think we should fuck so you don't feel left out. OMG son that was amazing! I forgot to mention the reason I'm so horny is I'm trying to get pregnant...
