Watch, for now.

My heart was pound in my ears as my girlfriend caressed her roommate. Her hand drifted down the girl's pale form until it disappeared underneath the covers. Li gasped, and settled onto Elizabeth's hand. The brunette offered Li the same opportunity, gyrating her hips until her partner experimented with a touch on her hip. Elizabeth took hold of this hand and gently placed it on her own sex.

A thousand thoughts rushed through my mind. Why had Elizabeth waited until now? Had she been planning this? What could Li be thinking, having my gorgeous girlfriend suddenly making love to her?

I was paralyzed in the doorway, watching the girls pick up steam as they fingered each other. Elizabeth broke off her kiss and tugged Li's tank top until she'd exposed a single, dark nipple. She expertly teased her partner, then her free hand found Li's waistband. Hypnotized, she lowered her skirt. My girlfriend moved herself into position between her roommate's legs, and earned an appreciative moan.

Then she saw me. Her eyes shot open and an instinctive hand groped for Elizabeth's head. As Li groped for cover, my girlfriend lazily turned back from between milky-white thighs. Li's embarrassment spread scarlet across her face.

"Oh my God! I am... I am so so sorry. I got carried away and..."

Elizabeth climbed up to pull her into a reassuring hug. "It's okay. Right, Ian?"

I nodded dumbly. We'd crossed the threshold out of innocent misunderstanding and into 'we've all seen each other naked now.' I wasn't sure what should happen next, but the room felt colder than it had a second ago.

"Why don't you, uh, join us in the bed, Ian?" Elizabeth trying to salvage the situation.

"Is that... would that be okay?" I looked at Li. It was her bed, after all.

Her face was bright red, and she'd pulled the covers up to her chin, though Elizabeth still lie gloriously nude beside her. "I... I do not think... I am not ready. I, well, I had my first kiss maybe fifteen minutes ago?" She shot a shy glance at Elizabeth, who grinned. "I... I would like more time. To think. Maybe tomorrow. I am... very curious... about everything."

Elizabeth looked at me. "What should we do?"
