If you want too increase your sitting time I suggest increasing five minute's each time. If your sitting for 15 minutes now try sitting for 20. When your comfortable sitting for 20 after a few days increase to 25. Keep increasing until you can sit for atleast 45-60 minutes straight. This may take some time and experimentation on your part but theres no need to rush it. Sitting regularly everyday is more important than the length your sitting for. Try to establish a firm minimum sitting time.
From Ajahn Chah:
Sitting for hours on end is not necessary. Some people think that the longer you can sit, the wiser you must be. I have seen chickens sit on their nests for days on end! Wisdom comes from being mindful in all postures. Your practice should begin as you awaken in the morning. It should continue until you fail asleep. Don't be concerned about how long you can sit. What is important is only that you keep watchful whether you are working or sitting.or going to the bathroom.

This is our foundation: to have sati, recollection, and sampajañña, self-awareness, whether standing, walking, sitting, or reclining. Whatever arises, just leave it be, don't cling to it. Be it like or dislike, happiness or suffering, doubt or certainty... Don't try to label everything, just know it. See that all the things that arise in the mind are simply sensations. They are transient. They arise, exist and cease. That's all there is to them, they have no self or being, they are neither ''us'' nor ''them.'' They are not worthy of clinging to, any of them. - Ajahn Chah
