i saw my sisters tits

i got home from school and took a shower which she walked in on me in. i quickly covered myself and then let go and said ‘shit i thought you was mom’ she was confused as to why i let go and stopped covering myself but she just left the bathroom. i finished my shower and got out and she talked about my dick again. as i left the bathroom she said ‘i told you it was big’. she walked out of her door in just a towel wrapped around her which gave me an instant boner. i said ‘yeah but it probably wouldn’t fit inbetween your tits’. she then teased me by dropping the towel just above her nipple and this made me act up. we laughed it off and she got into the shower. i walked into her room after it to see if she had finished the homework and she was only wearing a thong. my eyes instantly locked onto her tits. i was shocked and got instantly hard. i coukdnt even get my words out because of how astonished i was by how big there were. she said ‘what’ whilst giggling ‘ ‘ you never seen a pair of tits before’ ‘ not that big no ahaha’

‘i’m sure you have’

‘no they’re easily the biggest i’ve ever seen’ ‘ shame you can’t touch them’

‘ofc i can. who said i can’t’ i said to her

‘not me’ she said while giggling

i walked over to her bed and grabbed them. it nearly took me 2 handfuls to get 1 in. bear in mind she’s an E bra which is crazy. she started rubbing my cock through my pants which she was shocked by but she shouldn’t have been because she had seen it so many times lol. i was about to lean in and kiss her guy our mom and dad came home so she quickly threw on some clothes and i ran out of the room. before i ran out of the room i said to her ‘this isn’t over’ and she smiled and replied ‘i know’
