Another favour, but without any cards

With both Rachel and you being in no condition to continue the game, you decide on focusing your efforts on your guest for a moment - seeing as you can't just leave her hanging with this amount of sexual tension in the air.

"Kate...?" You ask her discreetly, and leave your housemate to try and calm down on her own. With all the puffing and weezing it's unlikely that Rachel takes much note of your doings at all, though you hardly think she'd take any offense if she could see you stealing a firm groping of the other girl's delicious boobs. "Can I ask you a question...?"

"Mmm, sure...?" She agrees, with a quick glance to your hand on her chest, and then with a lovely big smile as she pushes herself back into your open palm. "What about...?"

"Oh, I'm just being curious...!" You reassure her, and then make her follow your eyes as you look down to your housemate's rear - still turned upwards to the air, with both holes gaping and glistening with moisture. "Is it true actually...? That you're not into using your... thing on her...?"

"Well, sometimes I've had my doubts...!" She manages a quick smile, with obvious reference to how much she enjoyed just watching you doing it with her friend. There's a moment's hesitation though, before she continues in an even lower voice. "I've never seen it like this before... Is it... really as good as it looked...?"

"Possibly better!" You smile at her, and then daringly slip your hand down her body to caress her thigh, close to where it's meeting her hips. It's quite rare for you to tease even Rachel like this, as you're still unsure of actually touching her 'extras', but you can tell that the teasing is causing some immediate results to the firm bulge at the front of Kate's skirt.

"Uh, John...?" She's starting to object, but then hesitates, and eventually just tries to relax again while you change the direction of your advances. She's perfectly fine with your groping her breasts and bottom after all, and even lets out a soft little moan when you reach down under her garments to steal a touch of her underwear from behind. Unsurprisingly you find her panties to be completely soaked with her juices, and you just can't keep from tracing the outlines of her pussy through the silky material.

"I want you to do me a favour..." You whisper in her ear, while nibbling it softly with your lips, and notice that cute blush having returned to her cheeks again. It takes her a few moments to think about it, but then she nods her head slowly in reply - despite of your obvious lack of yellow tokens to give her.

"W-what is it...?" She mumbles uncertainly, while you guide her forwards, though you can tell by the look on her face that she's allready got a pretty good idea of it. Again it's making her hesitate, but she doesn't object when you gently start stripping her out of those last pieces of clothing, and soon she's standing entirely naked by your side.

"Just go ahead...!" You encourage her softly, and watch her take that final step as you give her a gentle pat to her bottom. Still she's looking back at you though, as if uncertain of what to do, until you step up right behind her - letting your own flacid member rest against her buttocks and the small of her back, while pointing her towards the gaping wet target in front of her.

"Oh, god..." She whispers as her cockhead makes first contact, and then her words are echoed by Rachel as you firmly help pushing her onwards. With a single slow motion you watch that hard long shaft slide all the way deep into the other girl's velvet snatch, and making them both gasp out loud in momentary shock at the sudden sensation.

Then Rachel looks back at you, seeming to wonder how you could get it back up so quickly, only to stare in even more of a shock to find Kate being the one to impale her. The look of utter surprise fades quickly from her face though, and is replaced with a similiar degree of gratitude for what you've managed to accomplish. And Kate seems to respond with the same kind of feelings as well, as you can feel her body trembling with emotion from doing what she's refused for such a long time.

From there it's certainly not difficult to get things going, though you remain directly behind them while Kate starts cautiously exploring this new sensation, and soon enough you help her rocking herself firmly against Rachel's upturned bottom. And then finally she's getting really into it, with short gasps of pleasure erupting from her lips, and her own hips starting to move and pick up the pace on their own.

"Now give it to her good!" You urge her on, whispering words of encouragement in her ear, while also heightening her pleasure just by fondling her firm breasts with both of your hands.

All of this seems to make for an incredible lovemaking, and you're quite surprised that Kate hasn't allready started cumming like a volcano inside Rachel's hot tunnel - especially as the action is allready affecting yourself, making your cock start rising back to it's full hardness again, until it's poking firmly into the blonde's slender back...
