My boyfriend and I have been together for almost 2 years now, and for 1 year and 9 months of that time I've been secretly fucking his dad and being his good little fuck toy.

My boyfriend and I started dating early in our first year of university, and we quickly fell hard for one another and were each other's first relationship. We were both virgins and had both promised each other that we would be each other's firsts when "the time felt right." He is very kind, quiet, sensitive, and gentle, and he was never pushy, controlling, or overbearing.

I first met his father about 2 months into seeing each other... and he is the opposite of his son in almost every way. He is loud, domineering, and very overweight when compared to my boyfriend's elf-like physique.

Since I lived away from my family and my boyfriend was from the city our university is in, I spent a lot of time with him and his dad... and that's where the trouble began.

While my boyfriend's dad was very loud and dominant, he could also be very charming at times and we got along surprisingly well.

One day I was hanging out at my boyfriend's when he got called in to work, so he asked if I was okay here alone with his dad, to which I said "of course."

We initially just watched TV together, but then his dad and I started talking. I told him all the details of how we met, what I liked about my boyfriend, and that we had promised our virginities to each other... although he hadn't made any moves yet and I was getting a little restless.

His father started talking about how he hadn't had sex since his wife died more than a decade ago, and he never believed in waiting for someone since "time is fleeting" that he didn't think I should wait any longer, and then he offered to be the first. I was quite shocked, but part of me liked how forward he was... which is the complete opposite of my boyfriend.

I thought "fuck it" and decided to take him up on his offer. We both agreed to never tell my boyfriend, and that was it... so I fucked him.

Ever since then, I've been his good little fuck-toy behind my boyfriend's back. His father's cock has defiled me in every possible way and I still haven't slept with my boyfriend. My boyfriend has started asking for it, but I just tell him that "the timing's not right" and "not to push me"... but little does he know that I've been a good little fuck-toy for his dad this entire time.

Am I morally reprehensible? Probably.

Do I care? Not at all.
