Fucking my colleague's sister

My colleague and I were at the pub have some drinks after work, when his sister joined us to drop something off. She joined us and we were having a grand time, till my colleague decided to call it a night and head home. She and I decided to leave after finishing up our drinks. She was quite a young looker and we had some serious sparks.

We decided on keeping the night going and ended up going to another pub for some more drinks. One thing led to another and we were making out at a corner booth of the pub. We made our way to my flat which wasn’t very far away. After we got to my place, and after a bit more kissing and ‘touching’, she said that she wanted to try something.

She goes into my room and comes back a few mins later wearing nothing but one of my shirts, barely reaching and covering her bum. She sat down in front of me and start speaking in office jargon. Playing along, I started replying back to her about projects and deadlines and how’s she not meeting them. She started apologising for not hitting targets and asked if there was something she could do to not get fired.

I sat beside her and told her that the punishment was a spank for each lost client and she had lost 21 clients. She winced and stretched herself out over my lap, her juicy bottom facing up, ready for her punishment. I said random companies out loud and slapped each cheek hard, with every slap, she let out a shrill while her pussy glistened with wetness.

After every slap she said she was sorry for losing them. Her cheeks were bright red half way through her punishment, I almost felt bad. I was rock hard by the time I was done spanking her. I told her she can start her performance improvement with communication and needs to be confident with her mouth and pulled down my pants. She nodded obediently and got down on her knees and began sucking me like her life depended on it. Slobbering all over and gagging hard around it as she blew me.

I couldn’t wait anymore and told her to stay where she is and started fucking her from behind. She was slick as water slide and tight like her jeans. She kept saying “sorry for losing the clients sir” as my cock stretched her pussy. I wondered how my colleague would react he he knew what I was doing to his little sister while I prodded her asshhole with my thumb. I was getting close to cumming, so I pulled out and stuffed her mouth with my cock again and face fucked her till I unloaded in her mouth. As her reward for being a good sister and employee, I ate her just fucked puffy pussy. She was wet and creamy from getting fucked that it didn’t take much to have her screaming to her climax.

She left the next morning after breakfast and giving me a quick blowjob. Her brother who sits right beside me at work is completely clueless.
