One night, I visited my friend's house and was drinking with him when he suddenly called his girlfriend over. Watching them flirt and get intimate right in front of me made me feel irritated, but I still agreed to sleep over with them. Late at night, I noticed the two of them starting to get close again. Not wanting to cause an awkward scene by interrupting, I decided to secretly spy on them. As I peeked, I saw my friend receiving a blowjob from his girlfriend—and then quickly ejaculating due to premature climax. After that, they both settled down to sleep. However, unsatisfied with her boyfriend's selfish performance, she noticed me watching and gradually began seeking me out for various things. How my relationship with her will develop from here raises intense anticipation.
