Still, I'd let this go too far already. I had to stop it now. "No."
He ignored me, unzipping himself with one hand while his hand firmly fastened at the back of my neck to force me down on his cock. "I helped you get off twice. Now it's my turn."
"Stop!" I hissed, digging into his thighs, denim under my nails.
But he didn't stop. "You're going to suck me, even if I have to make you. But I don't have to make you do it, because you want to."
Oh god. That made me both afraid and ashamed. Then, there it was. He showed me the swollen purple head of his cock. It was thick and rigid and my mouth watered to taste him. "You want to," he said again, more gently, bringing it close to my lips.
Oh, I wanted to taste him so badly that it took all my energy not to slide my lips over the head of him and take him all the way to the back of my throat in one stroke. But I'd already kissed him and let him watch me masturbate—two things I could never tell my boyfriend. I was just starting to come to my senses when the stranger thrust his hips up at my face, his pre-cum smearing on my cheek.
He was right. I did want to. It was just head, I told myself. It wasn't like I was fucking a stranger. I was just sucking him off. And all at once, my resistance faded away. I relented. I just opened my mouth and let him push his cock in. He was clean tasting and hot and hard. He tasted so good that I moaned around his shaft. With my mouth still on him, I knelt in front of him on the floor. Then he draped my coat over me to keep anyone from seeing.
Truthfully, I'd lost the will to care who caught us now.
His grip tightened on my hair to the point that it hurt, guiding my head so that I would suck him just the way he wanted. He looked down at me, and as we passed a streetlight I saw his eyes lock on mine. I knew he could see me, darkness or no, with my mouth held wide open around his shaft.
He let out a quiet groan. "You're a fantastic cock-sucker."
It embarrassed me, made me angry, and excited me. He thrust into my mouth, unmindful of anything but getting off, and his doing that made me crazy. I thought about how I must look to him now. I thought about what I must seem like to him. The kind of girl he must have thought I was...the kind of girl I felt like. I couldn't help myself; I ground against his leg with my pelvis and eventually put my hand back into my panties, wanting to get off again.
He noticed, and startled. Lifting the coat up to look at me, with my mouth full of him, he asked, "This turns you on, doesn't it, baby? Having my cock in your mouth makes you want to come again." He thumped the back of his head lightly against the seat as if I had admitted something intensely pleasurable or tragic. His grip loosened on my hair and his hand stroked my cheek before it returned to the base of my neck. "How many times do you want to come tonight?"
What kind of question was that? I felt like I was on fire. It seemed that the more times I came the more times I wanted to. I was at a desperately slutty point, and at a loss for words, I didn't answer. I just sucked him. But he stopped me. "Answer my question. How many times?"
He couldn't seriously expect an answer! My cheeks flamed, though I didn't even know that I could feel more embarrassment than I already was feeling. Searching for some sort of coherent answer, when all I wanted was to get his cock back into my mouth, I said, "A lot of times."
"Ten times?" he whispered, and his cockhead so near my mouth. It felt like torture that he wouldn't let me suck it!
I gave a small nervous nod.
"Twenty?"
I looked away, feeling like a total nympho.
He leaned forward and chuckled. "Suck me."
I was so happy to have his cock head push through my lips again. I was frantic for it. Though he had a kind of controlled, refined manner, I knew that the suction of my lips was having an effect on him. He angled his hips toward my face a few times, and I could feel him pulsing in my mouth. The occasional passing light through the tinted coach windows illuminated my face for him.
The wantonness of what I was doing made it certain that I had to keep playing with myself. I loved the idea of coming with his cock in my mouth, and I rubbed myself, even as I felt him pushing a little too far into my throat, gagging me slightly. He must have seen the desperation on my face, because, he whispered, "Are you going to come for me with my cock in your mouth, you good little slut?"
I didn't have to answer, because I just started a muffled scream with my orgasm.
It was the third time I'd come in close proximity and I was getting dizzy. I let the vibrations of my scream dance up and down his shaft. And while my own orgasm was ripping through me, he grunted once, and I could feel him filling my mouth. I wanted to pull away, but his sperm blasting against my cheeks was making me come that much harder.
Plus, he wasn't going to let me pull away if I'd tried. He held my mouth tight on him, my nostrils flaring wildly for breath, until I had swallowed every bit. Then, and only then, did he let his grip on my hair loosen.
I had loved swallowing a stranger's cum and he knew it.
"Put on your coat," he told me.
I was confused, and dazed, but I was growing accustomed to listening to him. I liked listening to him. So I put my coat back on and sat up in the seat next to him.
"Now go into the bathroom at the back of the bus. Take off everything you're wearing except for your coat, and then come back here," he whispered.
My eyes grew wide and incredulous as I hissed, "No way!"
But then, with a deadly calm, he looked at me and said, "I'm not asking you. I'm telling you. Because I'm going to give you everything you want tonight...and more."
