"Tess is your present, for tonight"

"Tess is?" You glance over at your girlfriend's sister, trying to process this revelation.

"Uh huh" She says, rising from her seat. She walks over to you slowly, looking as sexy as you've ever seen her. Her hips swaying in that long skirt, which she slowly hikes up as she approaches you.

Then climbs onto the couch, onto your lap, the skirt at her hips, her knees straddling you. Her face is inches from yours. Her lips are wet and quivering.

You've always had sort of a big brother/kid sister relationship with Tess. You've never thought of her this way. Well, maybe once or twice, but even then, it felt awkward.

As does this. Awkward, but good.

"Hey" she says in the same casual tone she always greets you when she says you, her lips inches from yours.

You respond back. "Hey Tess."

And suddenly she shoves you playfully. "Since when do you call me 'Tess?'"

She has a point. But still... "I don't think I could call you 'Greenie' right now," You respond.

"I think you should. I think you absolutely should" Tess says, her hand falling onto your chest, then sliding down your torso into your lap, finding your bulging crotch, wrapping her hand around it.

The moment is somehow erotic, outrageous, and awkward all at the same time. And you know your girlfriend is watching, though you can't tell what she's doing. "Okay Greenie," you say, "Let me ask you something."

"The answer is 'yes'" Tess pre-empts your question.

"Yes?" You respond.

"Yes, I do want to kiss you." And with that her lips are against yours, her tongue is in your mouth, your tongue is in hers. The kiss is long and passionate. Your tongues dance. Tess gasps with delight as you wrap your arms around her almost instinctively. You feel her fingers pulling your zipper down, then reaching into your pants.

Your bodies press against one another.

The flesh of her hand meets the flesh of your rock hard cock. She giggles mid kiss. Then finally pulls back. "Was that your question?"

You have to take a deep breath. You kinda wonder what Katie makes of all of this. But you're focused on Greenie right now. "Actually I was going to ask if this is as weird and awkward for you as it is for me."

She giggles again, her hand still wrapped around your manhood, "Yup" She says. "But it's also incredibly arousing don't you think?"

You open your mouth to speak, then realize you know better. You've always had a sarcastic conversational relationship with Greenie. "Do you really need me to answer that?"

Of course she doesn't. She can feel how incredibly aroused you are. "Okay. Then let me ask you a better question." she grinds her body against yours. Her words are breathy and seductive. You've never seen her this way before. She asks her question. "How do you want me?"
