This happened 2 months ago, when the three of us (all 21, [MFF]) went to a restaurant after a function where we ordered food and then had a chat. When it was about 11 pm, we exited the restaurant and bought some Alcohol and cigarettes. They asked me to drop me off to their apartment and then I obliged. Then as I was about to say goodbye and leave, they invited me over to have a drink and smoke with them, which I did. I’ll refer to the girls as “S” and “C” and myself as “R”.
S and C shared the same apartment so, we didn’t have much problems for drinking and smoking. We smoked, drank and had a chat. Then we had some dirty jokes too. At that time C started teasing me and S saying, “You should probably do it with R right now, S. Maybe I’ll join too!”. S was already red with the flush, after hearing that she was red as a tomato. Then C goaded her further saying “Maybe I’ll kiss R then”. After hearing that S jumped at me and caught me trying to kiss me. Then S and I kissed, seeing that C was laughing, and said “So blackmailing got you together!” C approached both of us and kissed me and S on the lips. S was a bit annoyed, but C whispered in her ear something convincing her to share.
