Well... Maybe that could be funny.

Yeah, you know what? Making two stupid futas horny beyond belief with your fantastic body but not letting them do a thing to you sounds like fun!

Not only do you deliberately squat so your ass is facing the two futa but you also hike up your shorts to really taunt them with what they can't have. You can't help but grin as you see the futa twins in the mirror get uncontrollably hard, their bloody shorts struggling to contain their girl meat.

A smile that fades as you see them start to walk over to you. You may have taken this too far.
