You have a boyfriend who is a streamer, he's 25 and you're 21. He usually streams games late at night around 10pm to 4-5am and most of the time it's like that. You two don't live together, he lives in an apartment and you still live with your parents.
He's not strict when you wear revealing and bold clothes because he knows you're good and he always acts intimately with you publicly even on stream whenever you're with him, so the whole world knows you're his and he knows you don't even dare to think of cheating on him.
While he was streaming and playing games, you suddenly went into his room and asked him to adjust your pants. You wore his jeans and they were loose, even sticking out the waistband of your underwear. He doesn't let you into the frame because he doesn't want anyone to see your sensitive scenes, he's always been subtle like that.
"You have to tie it up, it's too big for you, Kitten. Give me the elastic and I'll tie it up for you" he said softly then playfully slapped your butt.
