Before we went out with friends for a drink (including her brother) i told my gf to plug herself. After we returned at her house, she was horny. At first she dropped to her knees. After, i fucked her pussy for some time and she unplugged herself saying "fuck my ass". Everything was good until the time she started moaning. I felt akward because i knew that her brother was hearing her through the thin wall between the 2 rooms.i started going slower so that she gets a little bit more calmer. She told me to continue. Of course after some tine i gave in and fucked her ass like her pussy. Finally i cum insjde her ass, and i felt again awkward when i thought about the next day. Will my relationship with her brother be the same? Same with her parents. I dont know if they herd us fucking because their room is far. I think that she liked it and to be sure i loved it too but it will be for sure awkward tomorrow or the next time i see them.
