The Second Place Sister

... cock, but his hands were holding her firmly in place. Dr. Swell pushed the second “thermometer” into her virgin pussy, and she opened her mouth in a big “O” of surprise. When she did, the head of Ron's cock passed between her lips and settled there. He didn't push forward, but just let the tip rest between her lips. She should have been repulsed, but she actually felt quite happy to have something in her mouth. Her pussy and asshole were both filled, but Dr. Swell began to adjust the “thermometers,” saying something about the readings not looking correct. The effect was that both “thermometers” began to slide in and out of Tori's poor holes, creating conflicting feelings in her tummy. The motion felt really good, but she knew it shouldn't. She was breathing very heavily, and noticed that Ron had begun to rock his hips very slightly. The head of his penis was slowly moving in and out of her mouth. She should be disgusted. This was wrong! Nurses didn't put their penises into the patient's mouths. She should tell Dr. Swell what was happening!

She all but forgot where she was, so intense were the feelings in her pussy. Finally, the friction was too much, and her legs started to buckle.

Let it out,” Ron's cock was throbbing in her mouth, jumping up and down. She heard him groan, and then her mouth was flooded with a huge amount of the salty stuff she'd been tasting. She realized, right then, that she was getting her first taste of cum. She'd told the two girls at breakfast that it was gross, but as the tangy cream spurted into her mouth, she found herself swallowing it down greedily. It actually tasted very good! Her brain tried to process what she was doing, sucking down a big load of sperm from this stranger's penis, and when it registered, she came again thinking about how naughty it was. It was embarrassing, shameful, it was sick, and her pussy liked it. The fact that she liked it made her begin to to cry, and Tori was so confused. Her tears ran down the shaft of Ron's cock, which began to ...
