No rules, but a promise

"I'm sorry, but I don't have any rules or big secrets to swap with you..." You say to Rachel, seeing her smile grow wider while she leans closer to your exposed member. Before she reaches it you pull her up to your face however, sharing a deep and wet loving kiss with her before you continue with a throaty whisper. "But whatever you're up to, I'd want you to promise me that I'll get to return the favour in some way...!"

"Don't make any promises that you'll come to regret...!" She retorts at you, but with the same playful grin and excitement to her voice as yourself while she frees herself of your grasp. Then she wraps her fingers firmly around the base of your cock, forcing a moan from your lips, and just a moment later you can feel her tongue swirling expertly around the crown of your shaft. "Oh f-fuck, Rachel...!"

"Mmm-hmm... You like...?" She teases while licking her way down, and then back up again along your massive erection. Meanwhile she's starting to work her hand around the base of it with gentle but steady moves, and making you wonder where on earth she's picked up such excellent techniques - especially considering her claims 'not to be into any boyfriends'.

"If I do...!" You're gasping back at her, having trouble to keep your own fingers from cramping in pleasure and grabbing on tight to her soft dark hair while you're sliding them through it. Seeing just how good she is, you're no longer surprised at all by the look eagerness and pure delight displayed on her lovely face - as you too would surely have enjoyed it the same way, if you'd ever been able to give your partner such obvious amount of pleasure. "Easy though...! I won't last for long if - uhnnn! - you keep going like that...!"

"Don't worry, love!" She grins back at you, finally stopping her 'torment' of your extremely sensitive cock head, and then slowly start going down on you for real. In some ways her soft wet lips are feeling even better that just her tongue, as they wrap tightly around the very tip of your shaft, but somehow it's just not quite so intensive - not even when she's working her way downwards and her tongue returns to play with you inside of her mouth.

"I think I've found a new love in my life..." You confess as you can feel yourself reaching the back of Rachels mouth - her suction increasing while she start rising back up again -, and enjoy the curious glance she gives you in return. "I hope your boobs can forgive me, for the feelings I have for your lips...?"

"Mmmm, I dunno...!" She grins back at you as she reaches the top of your hardon again, licking away the thin strands of precum connecting you to each other, and adding the extra lubrication to her soft lips. "They're a jealous pair, those twins of mine...!"

"I'm sure they are..." You wink and then gently slide your hand free of her hair, down across her side, to grope at the aforementioned big babies that rests against your thigh while Rachel takes you back into her mouth again. "Oh well, perhaps one day I can learn how to share my love equally between every part of your body..."

"Mmm-hmm...?" She hums around your girth, making your shaft throb in delight with the motion, and then slowly returns back up for another quick breath of air. You notice a slight look of sadness or worry in her beautiful eyes however, as they return to your own, and though it vanishes immediately you can tell that she's getting uneasy again - especially as you make the mistake to try and comfort her by caressing her naked skin with your hand, moving down across her back and towards her raised behind.

"Changing positions a bit..." She excuses herself, slipping her lower regions out of your reach as she climbs out of the couch and place herself on her knees on the floor - resting her arms and full breasts on your thighs while she returns with renewed vigour to your crotch, almost literally setting your loins on fire with her skillful lips and fingers. "Mmmm, yeah... Much better!"
