Head home for the weekend

After blowing her, you kissed Megan goodbye and stepped out from her room and into the hall. You noticed the doors to Megan's roomates rooms where both slightly ajar, and you couldn't help but glance in. First you looked into your Stephanie's room. What you saw shocked you, looking away from you, Evan was riding Stephanie's dick cowgirl style. Stephanie had a dick too?! Suddenly Stephanie made eye contact with you through the cracks, she gave you a grin and held your gaze while she brought Ev to climax. You blushed and quickly averted your eyes, heading down the stairs. The rest of the party was cleared out at this point, and you saw the final roomate, Ariana cooking herfself breakfast. She was in a short white t-shirt and white panties. When you heard you come downstairs she turned back to look at you, her silky black hair swinging back, and you met her smokey dark brown eyes. She smiled, "Oh hey Noah, how was last night?" Turning to face you, you noticed a bulge in her panties, these girls really DID all have dicks. You blushed and glanced back up, seeing the little knowing grin that she held. "Did she slip that big sloppy cock of hers into your tight little ass?" She bit her lip, grinning, you saw her bulge swelling. "I know Megan is good, trust me, I know, but I fuck even better. I'll make you my little slut, so this is what I want you to do when you're going to sleep tonight and you take out your little cock to masturbate. Don't think of Megan, think of me." She leaned in, whipsering in your ear. "Think of licking my asshole, think about being my little slut, think about my cock." She pulled her cock out of her panties, it was smaller than Megan's but bigger than yours. "Maybe think about fucking my cute tight ass..." She turned around and pressed her ass against you, making you back away. And think my cock opening you cute asshole, and imagine me riding your ass and making you squeal like a girl." You cheeks were bright red, and after she said that you darted to the door, feeling a bit of shame for having an erection.

You get back to your room and settle in, inevitably you feel the urge to masturbate, but who do you think about when you do?
