I ❤️ My Teacher....

Okay ladies, this is kind of a confession/asking for help all in one. So when I was in high school I had a student teacher his name was Marcus in one if my English classes. It was a small class of 7-8 people so we all got very close. Marcus and I got extremely close. Like Marcus would come up to work and talk to me for hours and he still does come up to work every now and again, I run into him at the gym all the time I catch him staring at me. We didn't exchange numbers till I was graduated. Sometimes we Snapchat and text really innocent things the typical catch up things like how's school, how's work things like that. Anyways, I have an amazing boyfriend who I would do absolutely anything in this world for and he know Marcus and I are friends and, he seems to be really cool about it. But, sometimes when my boyfriend and I are having sex I picture Marcus. I love my boyfriend to death don't get me wrong I love our sex it's only sometimes I picture Marcus. I picture Marcus just wrapping me up in his big muscular arms, while slowly kissing me and inching his tongue further in my mouth. While, he slow moves his hands to my ass and starts squeezing and rubbing my ass. Then I rip off his shirt and run my hands down that amazing 6 pack he has while he puts his hand down my pants and makes his way inside my panties. Meanwhile, he is kissing my neck whispering in my ear tell me to call him daddy. Then Marcus throws me on his bed and we start having crazy, wild, hot, mad sex. I have never told my boyfriend this and I don't want to break up with my boyfriend but I'm dying to tell Marcus I have a huge crush on him... what do I do?!?!?! HELP!!
