Caught my ex on camera masturbating to something erotic on her laptop

I always trust my girlfriend to pleasure herself whenever I'm not in the mood for sex or I'm away. Admittedly, I'm jealous sometimes that I can't get her to climax as fast as she makes herself. Like on this video, with one hand rubbing her sensitive clits and another squeezing her boobs and gently caressing her pussy nipples, she has mastered the quickest route to a self-induced orgasm.
