Sex with my cousin sister

I live in a small city near mumbai not exactly near but close to mumbai i was always attracted to my cousin, but anything never happened. But once when during ganpati time she asked me to be in her room whole night talking seeing anime movies anything like that, during every ganpati my other cousins also come over, my other cousins are 21 and 23 but the one i like is 17 and im 16. So during that year of ganpati the other cousins went to their grandmas house for ganpati and didnt come over to our house. Me and all of my cousins live in a single large bunglow my cousin is my grandfathers brothers grandchild so its very long relation between us, we have 4 floors where all close family lives in a single floor she and her family her dad mother and grandparents live in ground floor i live in first floor, but while sleeping studying and hang outing purpose she has a room at the 4th floor where only 2 rooms are there one no one lives and a large gallery for view and one where she lives. During ganpati all my cousins stay in her room doing something watching movies like a saud before. But as i said this ganpati she and i was alone. As we entered her room it was 11:45 everybody in our home was asleep she locked the room and we entered the bed talking about some random stuff.(she is a kind of girl, i mean most girl feel inappropriate when someone not only guy or anyone touches or like their body touches their boobs, but she doesnt say anything most girls i mean would like push away a bit or feel tikle and do something she doesnt do anything. Our little cousin 4 yrs old always like cuddles her boobs she doesnt say anything or push or not let him do it she just stay quiet) similarly when like during we went out i always put a hand in her shoulder and stand like that u know what im saying, and sometime 1 year ago i accidently touched her boobs she didnt even look at me i mean there is always a reaction right like i touched ur private part or anything like that it was like i just touched her hand. At her room in ganpati we were watching a horror movie usually when we watch with other cousins we sleep in the bed upright and watch in tv. But today she said to watch in the ipad. I aggred, then while we were watching i came closer to her i mean my bkdy touched her casually. Then we stayed like that for like a 20 mins but after that when a horror scene came we both got very scared i like held her body in fear she too did the same, after than i tried to let go but she didnt so i didnt and we were watching the movie like that, our position was like hugging each other her boobs were touching me and my dick wasnt erect by that time then after one more jumscare she pushed her lower half of body near me and touched my lower half with her lower half her. She was wearing shorts her whole thigh was visible at that day she usually never wore shorts but today she wore as her pussy touched my dick. It erected it erected soo hard that i have never seen mine erect so hard because i think i never came into contact with a girl like this. I was sure she would notice that and say something because my dick was like against her pussy full erect 6 inches or something like that. She paused the video looked at me, then looked down under our blanket (we were sharing a blanket) and saw my erect dick on her pussy, i was sweating what shell say then she said "tera khada hogaya kya aree sorry for that re, toh thik hai baith jayega na ki karna padega" i was so shocked at that time i didnt knew what to say i stayed quiet then she said "thik hai phir mera bhi mood banade" then she kissed me and we continued to kiss lovebite at that time, it was awkward that i didnt say anything whole time😅, then she removed my shirt then hers, my dick was soo hard that whole time. Then she asked to remove her bra, so i did and before i could see her tits they touched my body. Then i looked at her tits and was amazed looking she said " chal abhi shuru hote hai" and removed her shorts and underwear. Then mine pants and underwear. She held my erect dick in her hand and inserted it in her pussy. It was cowgirl style, we continued it for like 15 mins until she said "my name and hone wala hai mera" then as i hear her moan i cummed in her i think that was the most quantity cum i had ever produced. After everything was done at 2 am she cleaned up and she asked "kisiko batana mat ha 'my name'. I said yes and she said " agar beech beech mai karne jaisa lagta hoga toh mujhe bata deneke ka na pehle hi kar liye hote".
