(This was originally filmed as a custom video and the name Jon is used throughout) Your step-sister is sorting through the dirty laundry and finds a pair of her step-mother's pants, all balled up and stiff... She can't figure out why they're like that, and when her mum walks in she explains that she just found them and she guesses they've been stuck down the back of the laundry basket for ages or something... Your mum says that several of her panties have been going missing recently, and they both agree that it's very strange! Then, a week later, your step-sister is doing the laundry again ...

(This was originally filmed as a custom video and the name Jon is used throughout) Your step-sister is sorting through the dirty laundry and finds a pair of her step-mother's pants, all balled up and stiff... She can't figure out why they're like that, and when her mum walks in she explains that she just found them and she guesses they've been stuck down the back of the laundry basket for ages or something... Your mum says that several of her panties have been going missing recently, and they both agree that it's very strange! Then, a week later, your step-sister is doing the laundry again and this time finds a pair of panties that are absolutely soaking wet and filled with cum... She's horrified and immediately realises that it must be from you! She exclaims over the amount of cum, saying there must be 5 or 6 loads in there at least, and decides to have a talk with you about it. She marches into your room and informs you that she knows about your dirty little secret; cumming in your step-mother's panties! At first you deny it, but eventually you fess up and admit you enjoy smelling your step-mother's dirty underwear.. Your step-sister teases you and tells you off for being a pervert, then says you should probably see a doctor about your masturbation addiction - it can't be healthy to be jacking off 6 times in a row! You say you don't know what she's talking about, there was only one load of cum in the panties! Your step-sister thinks you're lying, there's no way anyone could produce that amount of cum in one go, and when you insist you're telling the truth she eventually demands to see proof. You're surprised but agree, and so you get your cock out - shocking your step-sister with how big it is - and begin to stroke it for her. Your step-sister offers to take over jacking it to speed things up a bit, and gets down on her knees to stroke your huge cock - talking the whole time about what a pervert you are and how she just doesn't believe that you could possibly cum that much in one load... Soon you're getting close and your step-sister holds out her panties to catch your cum, but she's disappointed when you only deposit a normal amount into them! Just as she's beginning to gloat over how she was right and you're a liar, you start cumming again and absolutely drench your shocked step-sister in the biggest load of cum ever!
