Kirsi is a busty, big-assed mature woman who has been turning heads on Mature.nl since December 2007, and nearly two decades later she is still delivering the kind of explicit, no-nonsense content that keeps fans coming back for more. With 12 scenes spanning blowjobs, masturbation, lesbian action, and full-on fucking, this shaved and curvy mature performer knows exactly what she is doing in front of a camera. Whether she is riding a younger man or getting her pussy licked by another woman, Kirsi brings a raw, natural energy that no amount of scripted performance can fake. Twelve scenes, a loyal fanbase, and absolutely no signs of slowing down.

Kirsi made her debut on Mature.nl in December 2007 and has built up a solid back catalogue of 12 scenes that showcase just about everything this big-assed, big-breasted mature woman has to offer. Her most-featured niches tell you everything you need to know: blowjobs in 8 scenes, cum in 8 scenes, masturbation in 7, and a healthy spread of lesbian content, pussy licking, and shaved close-up action. Kirsi is not a passive performer. She engages, she leads, and she clearly enjoys every second of it.

One of her standout early scenes pairs Kirsi with Tom French in a classroom setting, where this busty mature woman takes on a younger man with full oral and penetration action including doggystyle fucking, blowjob and cumshot, all while showing off that signature shaved pussy and generous curves. In another memorable scene from 2013, Kirsi plays a mature housewife who gets exactly what she needs from a younger toyboy: masturbation, oral, and a proper fucking that ends with cum and leaves nothing to the imagination. Her old and young content is some of the most watched on her profile for good reason.

Beyond solo and duo scenes, Kirsi has also shown up in group settings. A 2009 sex party scene alongside Anouk, Paul Ripper, Pepper, and Zusa features multiple mature women sharing cock in a group blowjob and cumshot session that does full justice to the groupsex niche. On the lesbian side, Kirsi has appeared alongside co-stars including Salina, Charlena, and Halina K., bringing her pussy licking credentials and mature appetite to scenes that are every bit as explicit as her straight content. Nick Gill has also joined Kirsi on screen twice, adding to a co-star list that spans a wide range of pairings.

With nearly 18 years of scenes on Mature.nl and new content as recently as August 2025, Kirsi is a genuine long-term fixture in mature adult entertainment.
