(This video is also available in 4K!) You've booked yourself in for an 'ejaculation screening' at a specialist sexual health clinic, and after waiting months for your appointment, today is the day! When you enter the doctor's office, you're surprised and confused to see your STEP-sister waiting in there! She's equally bewildered to see you, and the two of you realise that you were supposed to be her next patient! Your STEP-sister admits that she hadn't told anyone about starting to work here, because of the sexual nature of the clinic, she'd been a little embarrassed! The two of you have a laugh about the awkward situation, and promise to keep this whole thing a secret from your extended families. Your STEP-sister then says she'll try to do her best to get you another appointment with a different doctor quickly, but it will still probably be a few weeks, as the clinic is very busy... You think for a moment, and then suggest that she go ahead and perform the test on you today. She initially refuses, saying that even though you're only her STEP-brother, she's known you for so long that she really views you as proper family! And because of the nature of the ejaculation screening... Well, she just wouldn't feel right jacking off her own STEP-brother! But you cleverly manage to convince her by reminding her that this isn't a sexual thing, it's a genuine medical procedure, for a serious test... And she's a professional, right?? So your STEP-sis finally awkwardly agrees! She takes you through a short questionnaire about your sexual habits, teasing you about your answers, then puts on her latex gloves to begin examining you. She's nervous and very giggly at first - doing her best to remain professional, but unable to completely put aside the fact that she's touching her STEP-brother's dick! She examines you gently, listening to your heart rate as she feels your cock and balls, and then begins to stimulate you. At first she's still awkward and tries to lighten the atmosphere by chatting away to you as she strokes, but soon she finds herself becoming aroused and fascinated by your cock, though she tries to hide it! Her words become more breathy as she asks you if you like what she's doing, and she almost even ends up dirty talking to you; telling you to relax and that she wants to make you cum... Just as you get close to orgasm she seems to remember herself a bit and grabs a specimen pot for you to ejaculate into, and she gently begs for you to fill it for her. She seems shy afterwards and apologises if she made things weird, she kind of got a little too into it towards the end there... After confirming that things are still cool between you, she says she's happy to remain your doctor for the follow up visits, and you'll be given your next appointment in a few weeks time!
