(This video is a bit cheaper because it's shot on my phone rather than my filming camera!) There's a rule in your house - if you're having trouble masturbating, your step-sister is supposed to help you finish! Your step-mom insists that it's unhealthy for young men not to expel their fluids often, so your poor step-sister frequently gets roped into helping you out. Today she's feeling particularly grumpy about this, and lets you know how little she's interested in helping you! You offer to go tell your step-mom that she's not up for it, but your step-sister doesn't want to get in trouble, so she reluctantly agrees to jack your cock, as long as she can keep looking at her phone. As she ungraciously begins stroking your cock, she complains a lot about how annoying you are and how none of her friends have to do this for their little step-brothers. She asks why you don't get your step-mom to do this for you, and you say your step-mom is always too busy. Your step-sister begins teasing you about how you'd rather have step-mommy do it, talking about your step-mom's giant tits and saying she bets you wish your step-mother was giving you a tit job right now with her huge saggy boobs! She notices that you're struggling not to cum as she says this, and teases you even more about how hearing about your step-mother's tits makes you want to cum! You beg your step-sister to let you finish in her mouth instead of onto the bed, and she grumpily lets you - sucking your cock fast and sloppily until you flood her mouth with a huge load of cum! She then tells you to make sure you tell step-mom that she was helpful to you, and teases you again about telling step-mommy about your obsession with her tits!
