Lisa tried to pull her mouth away from that hard cock in front of her to tell Emma that it was alright to knot her mouth. But Emma decided to pick herself up right before Lisa did that, and she grabbed Lisa's head to keep it down.
"I'm sorry, Lisa! I said I would give you control, but I can't take it anymore! I need to come right now."
Emma almost sobbed as she knotted Lisa's mouth. It felt incredible to have that tight and wet heat squeeze her cum out of her body.
A werewolf partner's body usually changed slightly to accept their mate's roughness. Lisa's body had changed in that manner as well, and she was able to take Lisa's knot easily down her throat.
However, that did not mean it was not overwhelming for Lisa to feel this.
Nick was still eating Lisa out, making Lisa's body spasm. She could not handle this much pleasure, and she ended up coming all over Nick's face.
