Staring at my breast

So my BF and I (together almost 4 years), are finally found a place and will be moving in shortly. Any way I had to go to his job to grab important papers that needed to go to my landlord. I pull up waiting for him to come out ( works in a warehouse), finally he’s out and looks like he is having a bad day. We just talked real quick, and noticed him staring but didn’t think anything about it. Hours later he comes home and goes “ Oh by the way you tites look good in that shirt.. I could see down your shirt. I just start laughing, and for whatever reason found it very hot and romantic. 🥰😘👀
