When I woke up in the morning, my sister-in-law's big tits were on my arm! I went wild at the sight of my sister-in-law's breasts that I had been longing for! I rubbed her breasts and played with her nipples and pussy, and I got an erection without even thinking! Then my sister-in-law woke up, so I pretended to be asleep... and she started sucking my erect cock! I couldn't stand it anymore, so when I woke up, my sister-in-law pretended to be asleep! So I did whatever I wanted to my sister-in-law who couldn't wake up, inserting and cumming inside her! I thought that my sister-in-law would get angry when she woke up, but this time, she made me fuck her until she was satisfied, in a divine turn of events!
