Sis becomes a whore ( part 1)

.me( kunal ) and my elder sister( lekha) went to the same college .I was a typical ugly guy and fat .I was in my first year of engineering. My sis was in the 3rd year and was totally opposite to me , she was hot and had big boobs .but no girl ever wanted to come near me .
Me and my sister went to a tuition together .the class contained me , my sister, and 5 other guys from 4rth year ( who failed almostevery test ) and our tutor ( mr babaj). Me and my sister sat down in a corner , and as my sister was deeply studying. The guys sitting opposite to us would try to look at my sisters cleavage as she bent to look at the text books .and took pics of it.
One day my sister had her sports match of football .she wore a sleevless tank top. She was covered in sweat .as soon as she came to the class the guys were stunned .looking at her sweaty body .her huge tits were half visible through the sweaty top.she wore shorts as she sat down beside me on our usual place and started studying. They could clearly see her fat tits dangling in her loose top .she wore no bra .my tutor had a hard on and looked at her tits with one hand in his pants .
As she came to the tutor to ask a doubt .he told her ” oh .this problem is difficult .but you can solve it .stand up and put your arms up and meditate on the problem. ” my sister obeyed .as soon as she closed her eyes .the 5 boys unzipped their pants and started jerking off vigorously. They didn’t even seem to care about me .the tutor jizzed his pants just by smelling her armpits . I wanted to shout .but part of me wanted to jerkoff too so I did .as soon as everyone finished jerking off .tutor told my sis to sit down .
That night I got a link to a whatssap group named ” fuck lekha ” .as I joined the group.it was filled with cum tributes to my sisters cleavage pics from the tuition. There were 250 members in that group. As i saw that they were from my school. Even the bus drivers and peons . There were even some deepfakes of her giving a blowjob. Then a boy posted a video of me jerking off to my sister .captioning ” we got the chance we have been waiting for ” .
