(This video is part 4 of a 5 part series, and is also available in 4k!) You and your sister have grown more and more comfortable since you started your 'wanking club', and you pretty much always watch taboo themed videos together now! This week it's your turn to pick the video again, and your sister is excited to see what you've chosen. As you settle down companionably to watch it together, with your sister teasing you as usual, you both relax and enjoy the video together; chatting away about what's happening on the screen as you each pleasure yourselves. After watching you stroke your cock for a bit, while she uses a vibrator, your sister asks if you don't find it boring, always just using your hand to get yourself off? She has so many different toys she can practically cum a different way every week, but you always just have to jack it... You say you don't really mind, but you guess it does get a little bit repetitive... She shyly suggests that maybe you could try something new, like using your hands on each other, instead of just on yourselves...? She says she knows it's a bit of a crazy suggestion, but she's really comfortable with you, and is it really that much worse than just wanking next to each other...? You agree that it wouldn't be a big deal, and you both move to sit closer to each other. Your sister nervously reaches for your cock, giggling as she begins to stroke it. She takes a second to get used to how strange it is to be touching her own brother's dick, then encourages you to start touching her pussy. You both begin to pleasure each other, a little awkward at first and with much giggling, then gradually getting more and more carried away. Your sister gets so turned on that she even offers to suck your cock, and though you're surprised, you agree to give it a go! You try to focus on the video playing in the background, but can't stop yourself from watching your sister as she worships your cock, telling you how crazy and dirty it is to be doing this... She gets more and more passionate and sloppy as she sucks you off, and you warn her that you're close to cumming... You can see that your sister is battling between her rational brain and her horny one, and unsurprisingly her horny brain wins out - she tells you to go ahead and cum in her mouth! You don't need much encouragement; you instantly flood her throat with spunk as she moans blissfully and swallows it all down... But when the moment has past, she seems awkward and worried; saying that she thinks she might have taken things way too far! She was just so horny, and got carried away... But she can't believe she actually just sucked her brother's dick! She says goodnight and heads to bed, leaving you unsure of whether your dynamic and the 'wanking club' has been ruined.... What do you think will happen in the final part of this story, part 5!?
