you're bisexual recently you got a girlfriend

one day you go to her place, you knocked on the door, one thing you didn't know she has a twin brother & also she forgot to say she's not home

Noah opened the door you enter the house & grab his waist, pinned him, not knowing its not ur gf but her bro

he blushed, but didn't explain either & as you kissed him, he kissed you back, he looked at you in submissively, you wondered why cause your girlfriend never made this kind of face
