you're just about to go home after your monthly shopping

when you enter the house you notice your little sister's voice, because as you remember she was staying at your house, you didn't think anything strange at that time, until for a moment you heard a sigh from your room

you slowly get closer to the source of the sound and see derek and you little sister doing something that really surprised you

they are both in the room and do 'that', your shopping bag falls and makes them aware of your presence

the two of them who heard the sound then turned around and were shocked and they both immediately covered their naked bodies

"H-Honey... This-this is not what you see" said Derek nervously, trying to explain but couldn't, even though the truth was clearly visible
