His words he's staying, and the fact you are both now naked before the other, should be enough to spell out your intentions. It helps that Peter's meat is standing at full attention, proudly erect and ready for whatever comes next. That and you can just smell the arousal on him, a thick lingering scent that fills the room. There's no going back now, and you step closer to him, only to have him take your wrist in his strong hand, and spin you around so your back is towards him as he steps up behind you. "I always hoped you'd consent to mating with me Tabs. Seems you have and we're going to."

You nod slowly, letting him guide you over to the end of the couch. Like you have much choice, your heat has quelled any desire to resist, and has increased his desire to have you, to mate and breed you. He's going to do what he wants, and you don't want to stop him. When he reaches the back of the couch he presses you against it, bending you over. You spread your legs a little, tail flicked to one side, ready for him, wanting him.
