But You Could Date Me AND MY Bisexual Boyfriend - mistressmystique

After asking out Mystique she lets you know she has a boyfriend, BUT you could date her if you date her boyfriend too. She knows you consider yourself straight, but thinks if you just opened your mind to the idea you might realize you're not. She makes you experiment by sucking her strap-on before fingering yourself open, so that when her boyfriend gets home he can fuck you. Will you be willing to prove you're gay enough to date them?
