You never seemed stressed about studying, but I certainly am. I'm having trouble focusing as it is. It certainly doesn't help when my twin br0ther opens up his jeans and shows me his pretty cock. I absentmindedly fiddle with your junk while still trying to study, but I just can't. Is this why you're so relaxed all the time? Because you just give into temptation? Even if I wanted to keep studying, I just can't focus. I take off my top and bra and start sucking and pumping my twin br0ther's hard cock until you cum all over my big tits. Then of course I find it really distracting to play with your cum! God, I'm never going to pass this exam.
