Stranger fuck! Pregnant from the brother-in-law?

I had ''unintentionally'' spilled yoghurt on my shirt and took it off without further ado, even though my brother-in-law was standing in front of me. I didn't care at that moment but it had triggered him a little and made him horny. I could clearly see his cock twitching in his pants. Of course I had to take advantage of that right away, even though my sister was asleep next door. So I had to be very quiet, but right after I had let him go, I had to groan loudly after he pushed it into my tight pussy. Oh my God, he had a great cock! Why didn't I dare to turn him on before?! He fucked me really horny in the kitchen so that I had to hold my hand in front of my mouth so that she wouldn't hear me and then something really stupid happened at the end....
