[F] 20 caught by my sister after a day of wild sex

For context my sister Katie is 3 years older than me. We grew up in a really religious environment and although we are close, sex has never been something we talk about.

One Saturday I had told my parents I was going to hang out with some girl friends and maybe see a movie. I left the house around 11 Am and went straight to my (secret) boy friends house. My parents probably wouldn’t have been mad about me having a bf but it was just a topic I didn’t want to bring up.

Anyway I had been having sex with this guy, Andy for a few months now and he had hinted that his roommate Jake thought I was sexy and wanted to fuck me. I kind of laughed it off, becuase while I thought his roommate was hot, I was super shy and almost embarrassed by the idea.

Any and have sex in his bedroom when I arrive. It’s pretty normal sex, I was still a shy church girl and hadn’t gotten into anything to wild.

I won’t go into details in this story but I end up fucking both Andy and Kyle all day. I called my mom around 6 to tell her I was going to a movie with friends and would be home around midnight. I remember my voice was hoarse from moaning and kissing and sucking dick, also the whole time I was on the phone Kyle was hard core fingering me.

We wrap up the wild day of sex around midnight and I head home. My parents are always in bed at this time and my siblings never pay attention so I’m planning on just going straight to my room. Well lucky me, when I open the door at midnight my sister Katie just happened to be walking by the front door, so she stopped to talk to me.

The first thing she said to me was “how was the movie?” Followed immediately by “Wow you stink”.

My hair was a mess and I had just spent hours doing unspeakable things so I’m sure I didn’t smell great.

My sister gave me an eyebrow raise like she knew what was up and then kind of squinted like she was trying to see better. Then she took a step closer and looked at me and said “What the fuck is on your shoulder Lily”.

She paused for a second looked at me and calmly said “ Ohhh My God you have cum on your shoulder”.

I think I just blurted out “Whatever” and hurried to my room.

She was right though, there was a big glib of cum that somehow ended up on my shoulder.

It’s not a big deal because I’m pretty sure she is sexually active also but it was hella embarrassing.

She still gives me looks anytime I reference and guy or she thinks anything is up.
