Samantha tells you to cover up.

Samantha sits up and leans forward so her face is a few inches away from you. "Is that what I think it is? you shouldn't brandish a weapon like that in public! cover yourself up". You can see a glint in her eye that tells you she's horney.

"Sure", You reply and pull Katies hands over your lap so they are over the top of your cock. She seems more than pleased with the idea and moulds her hands around your member. As Samantha stares at your jeans Katie starts to rub you hard through them for what seems like an eternity until she leans her head forward from behind you and whispers in your ear, "I don't think my hands are big enough to hide this, should I ask Samantha?"
