Stepmom Watches Stepson Jerkoff

Your stepmom walks in while you're stroking your hard cock out in the open. You're stuck, no chance to stuff it back in your shorts. She doesn't flinch. Instead she tells you to keep going. Might as well, she's the one who told you to. Before you know it she's got her own hand wrapped around you, sliding up and down. She leans in close, soft voice egging you on. Pretty soon your heart is pounding. How far are you both gonna take this? You keep pumping, and she keeps watching.
