Robin bit their lips a bit nervously as Abigail began to caress both their own and Xavier's bulge and slowly revealed them but let out a soft chuckle as Xavier offered them the choice of heads or tails, which they took to mean that he offered them to either have Abigail suck on their RealDoe or to penetrate her teacher with it from behind and as much as they did enjoy a nice long blowjob they also realised that they needed it less than Xavier, not that he in any way seemed to need any further inspiration. His cock was rock hard already and even leaked some precum. They looked down at Abigail who was going back and forth between the two cocks, the real one and the fake one. It was clear that she was equally enthralled by both of them.<br/>"I think I want to taste you both first," they said and smiled as they moved rather quickly and smoothly across the bed to Abigail's rear end and parting her legs took in the sight of her sex which already showed clear signs of arousal and with a wink at Xavier invited him onto the bed as well before burying their head between Abigail's thighs. They slowly dragged their tongue along the slippery, slightly opened, folds all the way from the clit to the orifice that was leaking all those delicious juices, poked  their tongue into it and went back to repeat. They went back and forth like that a few times with increasing intensity and pressure before wrapping their lips around the clit. They sucked hard on it for a few seconds before looking up to see if Xavier had figured out what they wanted from him in the situation.
