You're getting ready for a day chilling at the beach with your mom when she offers to help put on your sunscreen. You might as well slip everything off so mommy doesn't miss any spots...no need to be shy. If it helps mommy will strip down, too so you can rub her down. It's ok to get hard for mommy. It's perfectly natural...in fact maybe we can just stay home today while mommy has some fun with that big young hard dick. You should probably know she is ovulating, but that's no reason to hold back. Fill mommy with your seed. That's a good boy
