On Saturdays, I and my sister used to go to school/college at 6:30 AM and my dad used to drop us. I used to get the usual 4 AM blowjob from Mom before I got ready for college. Dad used to leave for office as usual at 8:15 AM. I and my sister used to return back home together at 10:30 AM on Saturdays. As my sister was around, I did not get chance to fuck mom freely. Once we are back, I used to keep looking for opportunities to see that my sister is not around and then used to kiss mom, or touch her boobs or insert a hand in her sari to feel her ass or pussy.
