Your penis enters the rex's vagina quite easily, given that the slit was easily 2 feet long, and open roughly 5 inches. Surprisingly, the muscles in the rex's vagina immediately clenched once your tip made contact with the walls of the orifice. 'What excellent muscle control,' you think to yourself as you begin to thrust. Behin you, the ending half of the rex's tail swishes back and forth, the only hint that she's feeling anything. 'Hm...' you think to yourself, 'how can i give her more pleasure?' You stop thrusting as you realize it. The rex lets out a low whine as you stop thrusting, not wanting you to stop.

You laugh, the rex grunts, and lets her head drop to the ground, landing with a light thud. "Don't worry," you say, rubbing the inside of her right thigh, "I'm just making this more pleasurable for both of us!" You pull out, scooting back slightly you lean over and have her vagina be at your elbows. Noticing what you are about to do, the rex relaxes all of the muscles in her vagina in preparation for your entry into her body.
