Quickie in abandoned building

F(19) M(20) so I was in fwb with a senior in my college he was this handsome athlete and before going for practice he used to meet me...one of the days when we were walking in our campus around 8 pm, we came through this abandoned professors building in which only one person used to live or maybe his family. We slowly went upstairs and on reaching 2nd floor he held my neck and started kissing wildly with all his lips involved and then his tongue in my mouth as my hands were on his shoulders his moved to my b**s and he started pressing them...,5-6 mins later he pulled my T-shirt up and started su king them making me me n and breathe heavily then I kissed him and gave him hickeys on the neck while he was pressing my b **b's after a while he said let's have quickie SO I also went wild and Pulled down my jeans his hands were over my panty rubbing smoothly and I was giving him handj0b as we were on stairs so I sat there and gave him BJ for 5-6 mins and then stood up and leaned back and he inserted himself in doggyy and started drilling me and I was moaning out his name slowly...then we heard some people coming So We both got dressed and moved downstairs while he went first and made sure nobody sees us followed him after 5 mins and then kissed him to his surprise....although we were undone but still have best memories.
