She's been studying under Amy.

Ellen looks at the ceiling, theatrically pondering your question. “Study. Lay around. Girl talk. The usual stuff.” As she speaks she moves her hips slowly, grinding her pussy over your crotch. She keeps her voice calm while she’s doing it, as if she’s unaware of her own body, but your eyes water up a little from the sensation.

You fight to concentrate and say, “Come on, Ellen. You’re acting… different. In the best possible sense of the word. What’s up?”

Ellen leans forward and puts her hands on the bed, holding herself at arm’s length from you. She continues slowly rubbing your crotch with hers. “It’s Amy. She’s been teaching me a lot. She’s just… she’s incredible. I’ve learned so much from her that I’m getting curious about other things.”

You stare into Ellen’s dazzling blue eyes and wonder what exactly she’s been learning from her roommate. Every lesbian fantasy you’ve ever had dances in your head. You don’t even notice the closet door sliding open.

“So how’s this for a sexy costume!” Amy declares.

You and the blond “cheerleader” turn to Amy. She’s wearing a bonnet like something from a Thanksgiving play and an ankle length gray dress. And that’s all. Her chest is completely bare, revealing the most perfect set of milky white breasts you’ve ever seen.

“What kind of costume is that?” asks Ellen.

Amy alluringly twists back and forth, swaying both her long dress and her supple breasts. “I’m an Amish prostitute.”

Ellen laughs. “Does that mean you won’t do anything?”

“No, it means business is terrible and I’m horny as hell.”

Ellen turns back to you and notices that you’re completely entranced by Amy’s delicious rack. “Hey! You better not be thinking that her breasts are better than mine.”

Amy walks over to the bed and kneels down, putting her breasts just inches from your face. “Sorry milady, but you can’t expect him to resist the double D goodness.”

Ellen punches the redhead in the shoulder. “I’m your roommate! I’ve seen your bras and they all say D-cup.”

Amy leans forward and buries your face in her wonderful chest. “All lies,” she says as she strokes your hair. “Your boyfriend here knows the truth.”
