Custom video based on scenario:
You are my older stepsister. You love dominating and humiliating men. Since I was a boy you noticed my attraction to female legs in pantyhose, which you like to wear almost every day. So you found it funny to start pushing me to also wear pantyhose, and then every night you trained me only to masturbate by rubbing my little dick like a girl would rub her clit through the soft and silky fabric.
After months I became so used to it, I was addicted and couldn't even get hard anymore without wearing women's pantyhose. Then you started me on strong female hormones, and now after more than a year I totally look like your younger sister, my body curvy and female, and trained to act and dress as feminine as possible. The video starts with you coming into my room for the daily training, complimenting me about how perfectly girly I look.
You, too, are wearing a skirt and blouse or a dress as well, and nude colored, sheer pantyhose that you know I like the most. Talk about how everything started and how nice I've turned out, being a perfect little pantyhose slut, as you know how much this still humiliates me every time you remind me. Meanwhile, order me to start rubbing my former dick that is now more a clitty, as the female hormones caused it to shrink to the size of a little nub, while other parts of my body like my breasts grew and became bigger and bigger. Tease me with your own pantyhosed legs, perhaps also starting to rub yourself as it makes you hot to see how much you've feminized your former stepbrother. Tell me it's time to train me becoming a slut for men. Order me to continue rubbing while you tell me to imagine how the guys look at me when I'm outside. How hot it will make me when they stare at my pantyhosed legs, my tits, my ass. How I will like when they start touching me. Make me fantasize about their big, erect cocks, and the strong need to suck them while you order me to rub my clit faster. How I will kneel in front of them, feeling the heavy weight of be my big tits hanging from my chest, while sucking and deepthroating their cocks till they shoot their load in my mouth, while I rub myself through the pantyhose because this will drive me wild. Then continue by making me imagine being taken from behind, doggy style in my ass , feeling submissive and used, and as feminine as possible. Perhaps even with multiple men at the same time, like a real slut! And when my still male mind will be humiliated and ashamed the most, you make me come but order me to continue rubbing, till I have multiple orgasms. That way you train me to get off on being used and humiliated. When I'm near orgasm you command me to moan like a proper girl, and afterward you tease me about having such a slutty stepsister.
