During one of the nights around 3am, I couldn't sleep as I was feeling very horny and started teasing my gf under the blanket. Things got heated up rather quickly as we both had not had sex for the past few nights.

The next time we know, we were in the doggy position and having a great time. She was controlling her moans, biting the pillow and pushing her butt straight into my dick for me to give it to her hard. I knew she orgasm when her butt started shaking and her head slump onto the pillow. I couldn't take it and CIP since it was her safe period.

At this moment, I suddenly felt as if we were being observed from behind. I turned around and saw my grandma standing there and looking at us! We didn't know what to do and quickly covered ourselves in blanket and pretended to sleep. I dun know how long she was there or did she see anything in the dark but she then casually walked to the bathroom before returning to her bedroom.

Of course my cum wet the mattress and we had to clean up after my grandma returned to her room. Even then we had to sleep on a wet patch for the night.

The next morning, my grandma acted normally and I wonder if she will ever tell my parents or maybe she really didn't see anything.

Grandma always acted normal because she hopes to carry great grandchild. If your parents allowed your gf to sleep with you then sex was expected unless you are that innocent.
