body: it was spring and my mom and dad had bussiness trips, so me and my sister where alone.
That night i remembered, i had a huge sex ed. test tomarrow on the oppisite sex and i had'nt studied I ran up to my room and started craming for the test, i was fliping around so fast in my schoolbook that my sis heard me she came in.
She asked what i was doing i told her and she said id never learn that fast and i had to take it slow so she came over and sat down on my bed.She stared telling me tips on spelling.,memory,ect.
After a while she got tired i think and her hand sliped of my desk to my crotch and she felt my huge erecttion from her teachings, she got a devilish look on her face and said maybe i can give you a better lesson.
I thought about this and agreed after that she said ok but dont cum in me i didnt take my pill.alright i said and we walked over to my bed and got nude, her ass looked better naked before i got comfy she said dont lay down, im gunna give u a oral exam.
