Thank you for all the positive response to the original, it inspired me to write this. Hopefully it makes for a decent continuation.
Also, thanks to LaRascasse for helping me with this.
Alex ended up sticking her head under the shower to clean off and rubbed her hair into a mess of damp spikes with a towel before hesitating at the door. Now that she thought about it, walking around totally naked in someone else's apartment felt weird, but wrapping herself in a towel to go straight back into the bedroom was pointless. She settled for covering herself with her hands as she walked down the hall, hearing much louder moans than before.
Victoria was bouncing on top of her girlfriend, the glistening strap-on disappearing inside her each time their bodies met with a slap. She was red-faced and panting, one hand propping her up over Sophia's chest while the other worked furiously between her legs, rubbing her clit and drawing out ragged moans.
Alex found her own fingers starting to move as she watched, her previously satisfied arousal flaring once more. She was usually something of a one and done girl, but after two mindblowing orgasms she was hungry for more. They were just too damn hot to watch.
"Fuck-" Victoria gasped, going rigid as her fingers curled into Sophia's skin. She shivered, her hips dropping into one more thrust, then let out a heavy breath, breaking into a smile. She shifted to let the strap-on slip out of her and leaned down to meet her girlfriend's lips, lingering as one kiss blurred into another until Sophia caught sight of Alex standing in the doorway and gently pushed her away.
"Don't be a stranger, Alex. Come cuddle."
Victoria looked over, a blissful smile on her face. "Yeah, you big horny hunk. Come here."
Blushing, Alex wiped her hand on her thigh and moved to lay on her side next to them, finding herself immediately accepted into the warm embrace as two arms wrapped around her. She could feel their breath on her skin as they all snuggled together, taking a break from pleasure.
Eventually, Sophia murmured, "So, Alex..."
"Yeah?"
"Have you ever used a strap-on before?"
"I haven't," Alex said, aware that this was leading into to something.
"I figured. But, well, Victoria has this fantasy..."
"Soph," Victoria protested.
"I have a few too," Sophia admitted. "To be honest, we've both really been hoping that something like this would happen."
"God, don't tell her that," Victoria groaned, rolling off Sophia's chest to lay side by side.
"It's okay," Alex said, resting her arm across both their stomachs. "It doesn't bother me."
Sophia smiled, kissing the side of her girlfriend's head and turning to peck Alex on the cheek. "None of it's bad. We've just kind of been... daydreaming."
"Uh. Yeah." That significant pause and the look in Sophia's eyes told Alex this was the kind 'daydreaming' you did with a hand between your legs, and she remembered her own shameful masturbation fantasies. The thought of them doing the same with her made her swallow hard. "I've... been thinking about this too."
Victoria perked up, half-sitting up to look at Alex. "Oh? Anything in particular?"
"Down, girl," Sophia said, laughing as she pushed her girlfriend back to the bed. "You can share if you want, Alex, but don't feel like you have to."
"Well..." Alex blushed. "It was mostly just about... this, happening at all. I don't know if there was anything specific. But, uh, what about you two? I'm guessing it involves me and a strap-on?"
"Yeah," Victoria said, staring up at the ceiling. "It's just your whole tomboy thing, and the muscles... I thought - well,
we
thought - that you'd be super hot with a strap-on, being all rough and dominant."
"Oh," Alex said, unsure. She'd never really thought about
wearing
a strap-on, much less using it to be dominant. "I'm... not against it, I just haven't... I don't know what I'd be doing."
"That's alright," Sophia murmured. "We're not expecting you to be an expert, but if it sounds like any fun..."
Alex hesitated for a moment, trying to picture it. Victoria underneath her, moaning her name and clutching at the bed as she pounded into her... It sounded hot as hell. She had been happy to let them take charge and direct everything so far, but she didn't want to stay passive forever...
"I'll give it a shot," she said, and Sophia broke into a smile.
"Okay. No pressure." She undid the harness around her hips and pushed herself upright. "Let me get this on you."
