I have a six-year relationship with my girlfriend and known her even longer. Her younger sister hit puberty hard and turns up to be better looking then my girlfriend.
In the evenings she sits on the couch with just a t-shirt and panties on. I can see her pokies through the shirt.
I think she started to notice me staring sometimes, cause she shows cleavage on purpose en even showed me a glimps of her nipples. She started texting me more often en asking dubious questions
