Then, letting his tongue dance along the path his fingers had just travelled, he soon centered his artful tongue on my protruding nub. His one aim; to...make it rise against his lips.He continually stabbed at it or pulled on it; making it rise from its hooded hiding place.He pressed himself against my rear, just slightly separating the cheeks so his hard arousal could rest between them. I knew he wanted to press it into me, for I could feel his arousal quiver as its head rested against that tight. I was fifteen minutes late to my appointment because I couldn’t find street parking and the lot on Fillmore was full.

There were a few short steps in front of the black grill gate of the building. Cathy began thrusting backward to match the forward thrusts of the Lab. The intensity of both increased until, as the three watched, the dog thrusted and held while his semen spurted inside his bitch who emitted a gasping whine as she too, climaxed."As you can see, she cannot yet control her orgasms, but that will come with further training."

I bring my hands up, running them through my hair, finding a rhythm as I fuck you, quickening my pace as we both get close. I’m whimpering, ‘baby, I’m so close’, begging you to come inside me. I keep bouncing up and down, harder and harder. Faster and faster, my pussy wraps around your cock, milking the cum from you. I feel your cock jerking, pulsing, throbbing. ‘I’m cumming.
