It's stepmother's day and the lady of the house is quietly expecting the best present she's ever had. And you deliver it in style - your hung friend walks in naked, his big shlong dangling between his legs and it's safe to say you've outdone yourself - she's stoked.
Of course you get to be the sweet cuck who watches the entire scene playing with yourself in the corner but today she lets you get some 'lubricant' to jerk your dick with. At first she wants to be licked but she's impatient and horny and can't wait to see you jerking yourself over her getting her hole used by your friend.
It's official, this is the best stepmother's day present she ever got!
