(This video is a bit cheaper because it's shot on my phone rather than my filming camera!) After you successfully taught your sister to cum last week by eating her pussy, she's come back today to ask for more help! She tells you that she's able to cum now with a vibrator, thanks to you, but she's still unable to cum from just penetration. She shyly asks if you would be willing to help her, since you did such a good job of getting her to cum before! She apologises and says she knows it's a big ask, but if you would be willing to fuck her and help her learn to cum on a cock, she'd really appreciate it! You agree but say you need some help getting hard, so your sister gets her tits out for you to admire. She giggles awkwardly as you caress and squeeze them, then when you ask her to suck your cock for a minute she's taken aback but agrees! She can't help but squirm nervously and laugh as she starts sucking your cock, apologising but saying it just feels so strange having her own brother's cock in her mouth! When you're fully rock hard you get to lay back and slowly enter her, encouraging her to relax and enjoy it as you begin to fuck her faster and faster. She comments on how much bigger your cock is than her boyfriend's, and how much better it feels with you, and in a few minutes she's close to cumming! You keep pounding her as she cums and she thanks you profusely, but then notices you're looking uncomfortable! You admit that you got very close to cumming yourself, and it's a bit uncomfortable for you to stop now, and your sister looks mortified and insists that you go ahead and finish inside her, saying it's only fair since you've helped her out so much! You gratefully start pounding her again and soon flood her pussy with your cum, shocking her with what a huge load it is! She thanks you again and says she hopes things will be better with her boyfriend now she knows how to cum, but she's worried that it just won't feel as good with him as it does with her brother...
