My girlfriend and her friends went a club the other night and got all dressed up. One of my girlfriends friends posted on her Snapchat story a photo of them in the mirror and I swiped up and said you guys look good and she responded with a “haha thanksss”. For reference she was wearing a white tube top with tight leather pants that make her ass look huge which is already big on its own. Also I just want to say I’ve never thought of this girl sexually before that night. Anyways later in the night she messages me and says that the other girls are blacked out and that she’s the only one awake. I say, “damn you guys must have had fun night” and she replies with, “yeahhh it was fun sooo which one of us did you think look the best”. At this point it’s late in the night and I’m feeling kind of horny so I say honestly I liked your outfit. She says, “oh really why is thatttt” and I told her that her butt looked nice in it. After I send that chat she leaves me on open and I’m thinking she’s going to tell my girlfriend. I guess not because 5 minutes later she sends me a mirror picture with her ass on the sink in a thong saying “how does it look now😈”. Ever since then we have been sexting on and off but I’m nervous to take it further.
