I Ate Pussy For My Boyfriend

I guess in high school at parties I was always one of those drunk girls who would kiss or make out with a girl but always in front of the boys to tease them of show off. It was kinda like flashing or sexting it was about being slutty for popularity sake. It was fun but not serious.
But my boyfriend who I have been with for 2 years as been pressuring me to eat pussy because he wants to see me do it. I mean, I didn't find the idea gross, but it's also not like I look at girls and want them either.
When I say he pressured me he really did. It's not that I said no ever to it but I was passive and he remained aggressive. We'd watch lesbian porn or mff porn together and he'd try to make me cum watching girl on girl. And always wanting me to do it. So I did... last week.
We have a mutual close friend we have known is bi since high school and she agreed to let me eat her out and for him to watch. We tried to make out but it was awkward because we know each other and while she was way more open then me about all this I was shy, weird and awkward. We were both naked touching and I was kinda freaked out. Finally my bf pushed my head towards her crotch so I just went there and licked the places i like licked.
Untill then I was more scared then turned on. But eating her pussy really got me going. Feeling her move, hearing her moan, feeling her breathing speed up... she started calling my name, pulling my hair as grinded my tongue on her clithood... she was telling me she was cumming...I could feel her shaking.... oh my fuck I was turned on.
Next thing I knew my bf flipped me over and was fucking me while she was kissing me and watching us fingerings herself. I orgasmed so fucking hard.
Sigh.
We havn't done anything more yet but now they both are pressuring to having open 3 way sex together where we all get what we want from each other.
I mean my first les-sex was great. But I feel like they might have been planning this. He'd get to fuck her too. I think I am ready for that but i can'tbe sure. I am very horny and worked up about what we did last time. But what if I get jealous?
I have a lot to think about.
