So Couple of hours ago i came home from a friends walk, in our house we have small fitness room where my sister training every day, when i bypass the room i came back and saw her training, she was in blue very tight leggings, when i saw this my dick stood up like a solider, she did the running so sexy, i went inside the room closed the door, she was wearing airpods, i sat on a chair pull my dick out and started jerking on this, she turned around and said what am i doing, how can i be so horny everytime, i said she is very hot and asked if she could help me, she said not now and she need to finish practice, she bent down to pick up the barbells and I went up to her pulled out my cock and sent it to her assI felt her warmth and vagina through these leggings, I started rubbing my cock on her ass.
she started to moan a little and I sped up, she asked me to remove my dick and then she would help me but it was too late I started rubbing my dick so hard on her ass that I felt that I was cumming and in a moment I finished on her leggings.
without hesitation, I took off these leggings from her and used my sperm on the penis to penetrate her ass, despite the fact that I had finished, I continued to fuck her very hard in the ass, she began to moan so hard that I wondered her parents would hear us, I lifted her by the neck and said that I would fuck her ass very hardshe started begging me to stop but i continued i inserted my fingers into her vagina and started masturbating her after that she begged me to continue and screamed very hardachal takhat’ yeshe bystreye
