Both.

Ellen’s fingers move around your cock, gripping it gently, and squeeze gently. "It's so hard..." she whispers softly, and then pulls your cock back towards her mouth.

"Your hands feel good, Ellen. Stroke it. Please" you reply, your cock twitching in the soft palm of Ellen’s hand, and inches from her face.

Ellen begins sliding her hands over your cock. Her juices provide a slick lubricant, and your cock glistens in the moonlight filtering in from a gap in the curtains. Ellen seems transfixed by the movement of your cock, and your reactions to every stroke of her hand.

You close your eyes, and lose yourself in the sheer pleasure emanating from your cock. Her hand slowly strokes you, and you can feel her hot breath on your shaft. Opening your eyes once more, you look down at Ellen, and watch her stroking your cock, her beautiful face only inches away from your erection.

"Suck it, Ellen. Suck me now"

Leaning forward, she takes your cock in her mouth, and swirls her around and over your cock as you slide it between her lips. Lifting her head off the pillow, she is soon bobbing her head and sucking hard on your shaft. Tasting the thick sweet flavor her juice, and the salty taste of precum. Saliva drips down her chin as she sucks. .

Ellen is enthusiastically pleasuring you, moaning lowly. Her golden blonde hair blurs in the darkness, as her head boobs back and forth. Your hand slides under the covers, and back between Ellen’s legs, which she eagerly spreads. You finger slips easily inside her wet pussy. You move your finger back and forth inside her, in time with her bobbing head, finger fucking her as she sucks you off. Her hips push back on your fingers.

Your hard cock pulses in Ellen’s warm, wet mouth, and as you thrust with your hips, she gags, and she pulls your did from between her silky lips. But after a few seconds, she says,

“I want you to cum. I want to taste you in my mouth.” She smiles a quick smile, and slides your throbbing cock back into her mouth. She begins to bob her head more rapidly, more frantically, like a wild animal, drooling all over your cock. The sound of her sucking, smacking lips on your cock fill the small room, and you’re not sure if you can hear Amy’s slumbered breathing anymore but you don’t care, and Ellen seem to have forgotten all about her sleeping roommate.

Seeing Ellen so unreservedly horny and animalistic was such a fucking turn on. You’d never seen her like this. The tingle of an approaching orgasm building shoots through your body, and Ellen can sense the change in you. Your thrusting cock muffles her cries of pleasure and encouragement.

Unable to hold back or give Ellen any warning, you feel the rush of orgasm, and gasp,

"I'm going to cum! Nnnnn I’m cumming, Ellen!" Ellen swallows several mouthfuls of thick, milky white jizz before pulling her mouth off of your spasming shaft. She jerks it off in her hand, as a stream of cum mixed with drool trickle down Ellen’s chin. A thick, ropy stream of jizz splashes on to her face, and she squeals with surprise. If that didn’t wake Amy, you think to yourself nothing will, but you still hear nothing form the other side of the room. You can see that the sticky fluid has landed on Ellen’s cheek and lips, and you also see a few droplets in her hair. Looking up into your eyes, Ellen smiles, and wipes the back of her hand across her cheek.

Licking her lips and the back of her cum smeared hand you happily note that Ellen doesn’t seem to be put off by the taste of your semen. As if to confirm this she moves forward again on the bed, and quickly licks your cock clean.

“That was fantastic.” You sigh, climbing back in bed beside her. She hands you a couple of tissues that she’d grabbed from a box on her desk.

“I’m glad you’re happy. I really got into it. It doesn’t taste so bad, salty, but I kinda like it.” She whispers, wiping your seed off of her face and chin.

“I’m glad you liked it. In the morning, we’ll have to finish what we started. As you snuggle in beside her, you resume your former position, your deflating cock pressing into the valley of Ellen’s smooth, soft ass crack, your body against hers, with your arm draped over her, your hand resting just below her breasts, your fingers entwined in Ellen’s hand. Lifting your hand, she gives it a soft kiss, and asks,

"Do you think Amy is awake? Do you think she heard us?"
