I'm cheating on her... no, I'm serious about it, with her best friend. She's been acting strange lately. She's been really excited ever since she joined the university club. And she doesn't want to have sex with me anymore. After she ignored my warnings and went to the club training camp, her best friend "Tsubomi" came to my room. She seems to have lost her bike key... Her panties are peeking out from under her miniskirt... No, no, I shouldn't be so conscious of it. "That girl is cheating on me... the training camp thing is a lie too. Things haven't been going well lately, have they? "Shall I comfort you?" kiss... alone in the room... I, I like her... right? But with this lucky turn of events, if she's cheating on me too, I should at least try once... I went with the flow and had an affair. This is bad... She pretends to be innocent and ignorant, but she's super erotic. Her kissing and blowjobs are incomparable to my girlfriend's, and she's abnormally sensitive and super erotic during sex... I'm such a loser for falling for her after just one time...
