我引诱了姐姐的男朋友，他在我里面射精！I Seduced my Sister's Boyfriend and He Came Inside Me!

I didn't expect him to come right now, so I had to improvise how to seduce him. I went to the bed and covered myself with a blanket, so he wouldn't see my face. Me and my sister have very similar bodies (and that big ass of course), so he should not see a difference right away. And it worked out! He started fucking me in doggy as he thought I am his girlfriend. It was so good I started moaning and here it is: he recognized a different voice. But does it matter now? Why stopping if he was inside already? We both enjoy it so let's continue! He fucked me in missionary and doggy and came inside.
