Outercourse!

"Sooo," you held still while looking into her eyes, "what do you want me to do now? Stop completely?"
She shook her head, "No, I like what you're doing, just don't go any further. Can I make you enjoy it more?"
"Sure," you said with a grin, "69 would be cool."
She smiled, "Good idea, take the rest of your clothes of, John"
You quickly took off the last bits of clothing while you watched her unhook and remove her bra and admired how she took off her panties. You hummed in appreciation for the sight of her wiggling breasts and her trimmed triangle between her legs. Your cock twitched and you lied down on the bed, "You on top, if that's okay."
She let her eyes roam over your body before she climbed onto the bed. She gave you a quick kiss then turned around and straddled your face. She bent forward and you felt her hot breath on the tip of your cock. Her fingers wrapped around your shaft, then you felt her tongue circling over your glans. You moaned and lifted your head a little to lap at her folds. Her clit was just out of reach and you gave a little tug on her hips. She giggled soft then her warm mouth enveloped your glans. Her hips swung as she shuffled back a bit, holding your cock in her mouth. You placed your mouth over her clit and held her hips still. The tip of your nose pressing against her folds and you got literally a noseful of her most intimate scent. It made your cock stiffen even more and it twitched in her mouth. She hummed in delight, sending vibrations deep into your shaft.

You used a finger to explore her entrance, slipping into her and feeling her walls. You heard and felt her moan and her pussy tightened briefly on your finger. You pressed on until your knuckle, then slowly withdrew. Your middle finger joined your index finger and together you pushed them into her wetness, coating your fingers with her juice. Another moan of her sent vibrations down your shaft. Your tongue flicked over her nub as you withdrew your fingers and felt her mouth lift from your cock. You pushed back into her and she sunk her mouth on your shaft. You grinned against her pussy and tried again to see if it wasn't a coincidence. She moved again in the same pace on your cock as you probed her pussy.

You both built up a comfortable pace. You took one of her nipples between your thumb and index finger and pinched it lightly. She moaned on your shaft, pushing herself slightly and briefly back into your face. Her hand left the base of your shaft and fingertips trailed over your sack and then you felt her nail scraping over your perineum. You thrust your hips up from the sudden sensation and almost choked her with your cock. Her finger didn't return when your hips fell back, instead she cupped your sack gently, almost as if weighing it. She withdrew her mouth, holding only your glans in it, then started to swirl her tongue over your slit and further over your glans. Your head fell back and you moaned loud, resisting the urge to thrust. You pulled your fingers from her pussy, then added your ring finger and slowly stretched her as you pushed in. Her moans made your cock twitch and pulse.

"Oh god, slow down or I'll come!" you said hoarsely.
She lifted her mouth and whispered, "I'll try not to make it too intense." She kissed your tip, "Enjoy."
You felt her closed lips pressed against your tip and she didn't part them but let your cock part her lips as she pushed down your shaft. It felt very tight and you almost exploded, then suddenly the pressure was gone and you gasped for air. Your cock twitched against her parted lip and you felt them slowly wrap around your shaft again.

You pulled your three fingers out of her and shoved two back in. You sucked on her clit while swirling your tongue around it. She moaned longingly on your cock, moving only slightly up or down on it. You bent your fingers and pushed the tips towards you mouth. You built up a slow pace of sliding in and out her, feeling and hearing her make weird high pitched moans. You slowed down even more, then felt a tiny spot with a slightly different texture on her inner wall close to her clit. You experimented with pressure and strokes while she moaned in all sorts of pitches onto your cock. You ended up making tiny circles with one fingertip with light pressure which made her moan in a very pleasant pitch. She sunk her mouth onto your cock, you felt and heard her gag and move back only a little. You continued to massage the magic spot and she plunged back onto your cock, moaning with her special moan. You felt her swallow on your glans and your cock began to pulse again. She quickly drew her mouth back and you increased the speed of your massage a little. She threw her head back moaning loud, "Oh god, yes, that's the spot, don't stop, John." You felt her legs tense and her pussy tighten as her moans increased. You grinned on her clit, wondering briefly how the other students would think about you. You pressed the tip of your tongue firmly against her clit and pressed a little harder while you circled her g-spot.

Her back arched up and her mouth sunk on your cock, then her back fell and she lifted her mouth moaning loud. It looked like her body started to ripple, her hips began to shudder and her mouth tightened on your cock, sucking you harder and faster than before. You felt her exploding on your finger as your cock began to throb. Her lips sunk onto the base of your shaft, her moans cut off while you felt her swallow on your glans. Her pussy spasmed on your fingers as she withdrew only a little and breathed very heavily though her nose between low grumbling moans. The sound vibrated deep into your shaft and down into your body. She cupped your sack a little tighter as she seemed to try to suck your seed from your sack herself and you exploded into her mouth. You cock throbbing hard with each jet of your seed, almost painfully so. You felt her moans on your cock in between it all. You threw your head back, your moans loud and ragged as she continued to suck and move her mouth up and down your shaft, milking it till the last drop and beyond. You tried to utter something when it became almost too much, but it got drowned in your moans.

You felt her hand move to the base of your shaft, the vacuum of her sucking disappear and her lips slowly sliding towards your glans. You kept moaning between ragged breaths and shuddered when she swirled her tongue over the tip of your glans, lapping up the last remnants of your cum. She lifted her leg and dropped down on her side next to you, panting with ragged breaths. She stroked your lower belly and over your upper thighs and back, occasionally quivering with a soft moan. Slowly you drifted away with a big smile enjoying the afterglow and her sounds.

You awoke a bit later from cat whistles in the hall. As you perked up on your elbows, Lisa stepped through the door carrying the pizza box, wearing only her bra and panties.
She smiled as she saw me, "I think that means you scored, John?" nodding towards the hallway.
You grinned like a Cheshire cat and nodded, "Yes, that's what it means. Where did you go?" She opened the box and held it out in front of you revealing two piping hot pizza slices and two small cans of Caf-Pow.
You laughed, "Well done, Lisa," then tried to look more serious and grateful, "That was truly amazing! Sorry that I dozed off."
She caressed your belly and leaned in to kiss you, hovering with her lips above yours. She whispered, "My pleasure." Then kissed you tenderly.
She broke the kiss suddenly and balanced with the box, then laughed, "Almost made a mess."
You grabbed a can of Caf-Pow and drained it almost completely in one go, gulping it down eagerly. She smiled as she watched you, then placed the box on the bed as you sat up.
You both ate a slice and smiled with satisfaction. Afterwards Lisa drank her Caf-Pow and got dressed.
She sat down on the bed next to you and caressed your leg, "It was great, lots of endorphins released tonight," she chuckled.
You nodded and grinned, "Yeah, I wonder if you could overdose on them." then winked, "I think this came quite close."
She planted a kiss on your forehead, "It's getting late and I'd like to sleep in my own bed tonight. Yours is a little small for two. I'll see you in class," she paused, "or call me, I'm on the list."
You gave a nod and smiled, "Have a safe trip home, Lisa, see you soon."
She blew a kiss and left your room. You could hear more cat whistles down the hall for a little while then everything turned relatively quiet again. You leaned back and drifted away.
