It’s your 18th birthday and I need your help with picking out an outfit for me to wear for your party. I try on some revealing dresses and then some lingerie and ask for your opinion. I can see it’s making your cock hard so I tell you to start stroking it while you watch me. I then offer you a helping hand and stroke your cock and give you a blow job until you cum in my mouth, don’t tell your step-mom about this!
