(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 sister is supposed to help you finish! Your mom insists that it's unhealthy for young men not to expel their fluids often, so your poor 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 mom that she's not up for it, but your 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 brothers. She asks why you don't get your mom to do this for you, and you say your mom is always too busy. Your sister begins teasing you about how you'd rather have mommy do it, talking about your mom's giant tits and saying she bets you wish your 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 mother's tits makes you want to cum! You beg your 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 mom that she was helpful to you, and teases you again about telling mommy about your obsession with her tits!
