This is starting to remind me of my own fics in reverse.

This chapter isn't bad by any means -- I do enjoy it -- but to be honest it's probably my least favorite of the bunch. I wish I could put my finger on why -- I don't like to criticize without something helpful to say.

I dunno, maybe I'm just not into romance.

Perhaps the lack of Dash and her zipzapping cock?

See, when I was in high school, whenever I tried getting into a research project like this with a lady partner, I always ended up doing it by myself.

I'm not sure. Obviously I like Rainbow Dash, but I still like the other chapters that don't involve her more than I do this one. I guess...perhaps those others each feature a more dynamic match-up of personalities than the two nerds?

When it becomes Sci-Twi's turn well Sunset Shimmer will have a all-around ticket to Continuous City.

I hope you're going to write about Twilight's turn with the amulet, that would be awesome.

I would take Twilight saying that "Pregnancy isn't a concern with it" with not much grain of salt since if "Everyone's Best Friend is Twilight Sparkle", Twilight still manage to get pregnant despite saying the girls even with their dicks couldn't get anyone pregnant. I feel by the end of this Rainbow would still get one of the girls pregnant

I don't think this is in the same universe though, so that argument might not count.

While this was super hawt, I'm very glad that you kept it tender and loving and amorous the entire way through. Makes for a good wombo combo.

Sunset Shipper

Most appropriate typo ever.
