I swung harder and faster, my knees clamped on her rib cage, my butthole grazing her flat belly, and my shaft plowing a channel between her young titties. "Oh, Jill, this is awesome!"
"What should I be doing?"
I felt my pleasure rising, and wasn't particularly inclined to answer her. I just kept swinging, sliding up and down in her cleavage. But she seemed to want to be a more active participant in the proceedings She tucked her chin down to her chest, and pursed her lips. Her mouth could almost reach my cock head on it's closest approach to her face. Not one to pass up a good thing, I lengthened my stroke, and managed to reach her pouty lips.
She brushed her mouth against the raging purple head of my cock. The feeling was incredible. I continued to pump, faster and harder, and further up toward her face. On each stroke, she got a little more of her lips onto my cock head. After ten or fifteen strokes, she was getting most of the head in on each swing. Then she started using her tongue, swirling it and licking it each time around. I felt my balls tighten and the blood rushing in my ears. This was definitely working.
My brain stopped analyzing the situation, and my actions became more and more of an automatic response. All I knew was that I was swinging at the hips, my cock shaft was nestled in a slick wet valley, and my flaring cock head was engulfed in a warm, sucking mouth at the apex of every stroke. I was also dimly aware of her intense, beautiful face, doing its best to bestow pleasure on my most sensitive organ.
The pleasure response got stronger and more intense. My cock was on fire, my heart was pounding, and I felt that familiar feeling of inevitability. My hips began to buck and my fists clenched the sheets. My cock lurched, spasmed, and spat a huge gob of jism in a great arc. It landed squarely on her nose.
"Hey!" she screamed, as rope after rope assaulted her face. The first one had gone up her nostril; the second one hit her in the eye. The next few whitewashed her cheeks. After that, she managed to turn her face to the side, and then smacked me in the side of the head with her fist, knocking me over onto the bed.
I lay there on my side, my hips convulsing, my cock still spurting. She was grabbing sheets of Kleenex, trying to wipe the sticky blobs of jizz off her face.
"Andrew! You are a pig!" she was yelling. I just lay there, delirious, an idiotic grin on my face, as my cock continued to leak creamy white cum onto her sheets.
After a few minutes, I came to my senses and sat up. "Thanks, Jill! That was great!" I said.
"Get your clothes and get out of here!" she screamed, throwing my underwear at me. "And don't call me again, you jerk!"
Still grinning, I pulled on my trousers and shoes, stuffing my briefs and socks into my pockets. I held my shirt in my hand as I backed toward the door. "See you tomorrow after class?" I asked.
She smiled sheepishly. "Yeah, I guess so," she said. "And it's gonna be MY turn to cum, you bastard!"
