While on a visit with your Step-Auntie Diane, you tried to relieve some pressure in the other room when Diane walks in and catches you with your hand down your pants. Far from being upset, she encourages you to take it out so she can show you a few things she's learned in all her years of experience. After stroking your cock for a bit, she gives you something to look at - opening her robe and removing her bra to grope and squeeze her little tits. After some more stroking, she gives you a peek at her grey haired pussy, then leans over to suck your cock nice and hard. Needing some release of her own, she slips off her panties and leans back to rub and finger fuck her fullbush pussy for you. You both continue to masturbate, looking at each other, until she can't resist you anymore and makes you cum hard with her mouth and hands
