Not necessarily. If you consider handjobs or blowjobs hardcore, then it certainly appears she did some of it on camera. At the very least (in all the various Twitter pics) we see her holding on to guys' dicks repeatedly, and a guy with his fingers on her clit twice. But some producers might only consider full penetration to be hardcore. Maybe JayRockContent feels that way, but she feels what she did on camera is close enough. It's certainly a very big step up from bikini posing lol.
There is also the distinct probability she made some private 'selfie' videos with her 'camera on a pole' (which she has done for her website with the 'softcore' squirting video), with this Alex guy alone, then also with both Alex and Isaiah in a different location, and will release those videos (if at all) only to her die hard fans & supporters. She DOES appear on MyFreeCams, and there ARE some guys on there who will tip the living hell out of her for videos like these--we are talking 4-500$ or more each customer. Or the guys who simply tip her lavishly, as they are in love with her, as some webcam customers will do. And to those guys she might feel generous and trust them with a little 'bonus' material.
I don't care if she's a tease or not. It's an excellent marketing strategy, and she is hot enough to make it work however she does it.
My guess would be that in time she will take the plunge and go all the way. Whatever she does, you can bet the guys will eat it up, and that she will do it with style.
My advice to anyone who wants to see more, even if she stops with the teasing Twitter stuff about it & never releases anything more than 'hanging into the dick' assists for other girls--get to know her on MFC, tip her well, be polite & patient & above all do NOT hound her about it lol.
I am not a shill for her or MFC, I don't even know her. I just admire her and I know how the business works.
