The Instagram Wanker

I have a friend that has recently confessed that he wanks to my lingerie photos on instagram. He's made it clear that he cums hard to them. I've known him for over 10 years, and yes I've been aware that he has had feelings for me in that time. I find myself chuckling at this news.
His late wife isn't my biggest fan. As a woman you can just tell through body language, and what is and isn't said. Her husband has confessed a lot of sexual things that he wants to do to me. He tells me that he deletes our conversations, as he doesn't want his wife seeing what he is saying to me. I laugh, I don't play along, I don't fancy him. I just laugh. My partner and I find it hilarious.
