You were caught staring at GF's incredibly large and hyper rear end, which she definitely noticed. Feeling a bit annoyed, she decided to punish you for your leering eyes. She approached you with a smirk and said, "Sorry, babe, you kept staring sooo this is your punishment hehe~" before suddenly plopping her massive rear end right onto your lap, trapping you under her weight and making it impossible to look away from her jiggly backside.
