We picked our way down the narrow stairs to our vantage point, finding that if I stood behind Beth we could both see. We didn't have to wait long, hearing the door of the flat open and close, and the girls came into the bedroom, Ann's arm round Pippa's waist. "We were right," I whispered.
"Of course," teased Beth, turning for a second to kiss me.
The two embraced, then Ann moved back, hands on the shorter girl's shoulders. "Our own bed, finally."
A shy smile from Pippa. "Mm."
They kissed, softly at first but then more passionately, Pippa running her tongue up Ann's chin and over her lips, then letting Ann catch it, suck the tip, kiss her again with wet lips. "Wow," breathed Beth. "That looks amazing."
Ann's hands were roving over those curves of Pippa's that had attracted my attention, and the hem of Pippa's top lifted now and again to reveal a tantalising hint of creamy skin. Pippa raised her arms, letting Ann pull her top over her head, drop it on the carpet, and I couldn't help my deep breath. "Mm, those breasts."
Beth chuckled softly. "Maybe they remind you of someone?"
"Mmhm."
Ann's top was next to go, her breasts almost just bumps in comparison, but Pippa's fingers moved on them with the same enthusiasm, then reached to unfasten Ann's bra, let it drop. Her mouth sought a nipple, and Ann tilted her head back, ponytail dangling. "Ohh..." we heard.
The other nipple, and Ann's fingers cupping Pippa's breasts through lacy fabric. Pippa slid her bra straps from her shoulders, letting Ann tug the bra down, fingers returning to soft flesh then drawing slowly together to roll nipples between thumb and forefinger. "Oh god," gasped Pippa, "you're making me so wet."
Ann's palm flat on Pippa's chest now, gently urging her towards the bed, and Pippa sank onto her back, Ann slipping down her jeans, revealing more curves, thighs, bottom. Ann knelt, bending to kiss Pippa's mound through her panties, dab her tongue on the obviously-damp fabric a little lower down. "Ohh..." Pippa's whispered response. "Take them off."
Ann's fingers hooked through elastic, and Pippa parted her thighs again, Ann's mouth finding its destination. "Mm - yes - oh, a little faster," begged Pippa, Ann's fingers exploring her while Pippa squeezed her own breasts together, pulled at her nipples. "Oh - Ann - I'm nearly -"
Her body tensed, thighs tightening round her lover, and we could see Ann almost fighting to keep her mouth in place as Pippa's hips flexed, trying to prolong her pleasure. But finally Pippa broke, gasping, her fingers gently signalling Ann to stop, at least for the time being. Ann moved up to wrap her arms around Pippa, stroking her hair, and the two kissed again, Ann's face still wet from what they'd shared.
Beth let out the breath she'd been holding. "Mmm..."
I slipped my hands inside her t-shirt, cupping her breasts, feeling her nipples hard against my palms. "Want to go back up, first time in our bed too?"
She shook her head. "I want to see how Pippa returns the favour - though if you touch me like that while I'm watching, I might just - well, you know."
I blinked. "OK."
We looked again, seeing Pippa shifting position, her head now on the pillows. Ann slid her body across Pippa's, and Pippa reached down to press her fingers between Ann's thighs. "You sure you don't want to lose the panties yet?"
A shake of the head, and Ann began to flex her hips. "Mm, that feels like I'm kneeling over him, I'm pushing myself against his erection, teasing him because my panties are in the way so he can't be in my wetness, but I can tell he's getting close anyway, maybe I use my fingers to pull my panties aside so he gets just a little more of what he wants, and when he feels that, he can't help himself, he pushes up against me and groans, all his white stuff is just spurting out, most of it goes on his stomach but I'm still moving, the front of my panties gets all sticky too..."
Ann paused, her face flushed. "God, Pip, I don't know whether I want your fingers in me, or to be kneeling over your mouth, feeling that tongue of yours."
Pippa chuckled softly. "Plenty of time, you can have both. Fingers first?"
A wordless nod, and Pippa's fingers slid inside Ann's panties, then obviously penetrated her, Ann giving a delighted gasp. "You naughty girl," Pippa teased, "you were pressing against him like you said, but you just couldn't resist, you pulled your panties aside and he was in you, he hasn't forgotten you told him 'no', but what man's going to stick to that when he can feel you, see you? So you're getting fucked whether you meant to or not -" Pippa's fingers followed her words, thrusting deeply into Ann - "and you feel him stiffen, you know what's coming, all that sticky stuff is spurting where you really wanted it in the first place -"
I heard Beth's soft moan as Ann's climax overtook her, her hips pushing down on Pippa's fingers, a trickle of clear liquid down the inside of her thighs, her body shuddering. "Ohhh..."
I felt Beth push her hips back against me. "Oh, my nipples, now," her voice begged, and I brushed the pads of my thumbs over them, then pinched gently. Beth's response was electrifying, her body tensing, her lips making an O, then her hand over her mouth to suppress a moan which would surely have carried into the bedroom. "Mm," she breathed finally, "that's... new."
I took her hand. "Come on... I know Pippa promised Ann something else, but I think we can leave them to enjoy that by themselves - right now there's something I'd quite like to give you too, what Pippa imagined has put an idea in my mind..."
We reached our own bedroom, and Beth shed her clothes, leaving only her panties - "If I've guessed right?"
I nodded, undressing and sprawling on my back on the bed. Beth slid over me, pressing damp cotton against me - "Like you imagined?"
"Mm -" I gasped. "But you have to choose - Ann's ending, or Pippa's."
Beth grinned wickedly. "Let's see how long we can make this last before I have to decide."
She flexed her hips tantalisingly, watching my face, and every time my expression betrayed that I was close to the point of no return, Beth slowed, stopped, lifted her hips from me. "Mm," I breathed, "I don't think I'll last more than another couple of times like that."
Beth chuckled. "We've not played out everything they said yet."
Her fingers hooked through her panties, pulling them aside to reveal her soft pink folds, wet, slippery, and she lowered her hips again till I could feel her against me, no barrier. She rested there, not moving, and I took a deep breath. "God, Beth, that feels so good, almost like I'm already coming..."
She moved just a fraction, and my eyes widened at the sensation of being right on the edge again. "Just a little longer," she breathed as she lifted from me again.
"I don't think I -" I began, then words were suddenly impossible as Beth used her fingers to press my tip against her centre, then sank down, my hardness penetrating her. "Oh, naughty boy," she echoed Pippa's words, "you weren't supposed to -"
It was her turn to lose words as I pushed my hips up towards her once, twice, then our mingled cry of satisfaction as she felt me spurt into her once, then again. "Ohh..."
Beth finally relaxed against me. "Did I guess right?" she teased, her eyes dancing.
I nodded. "Now... remember what Pippa promised Ann?"
"Mmhm?"
"Well - I can't possibly give you less than Pippa gives her lover, can I?"
Beth's face showed that the penny had dropped, and without hesitating she moved upwards. "You sure you don't mind, all your stuff being in me already, I think some of it's come out..."
I shook my head, starting to tongue her, hearing her gasp softly. "Anything for you, my love..."

Beth stirred, opening her eyes. "Mmm..."
