Lou came back in the room with a third bottle of wine and sat slumped onto the sofa . "It's been a crappy week, I think we deserve this."
Jess grabs the bottle and feels their glasses to the brim. "I'll not say no to another glass, but I thought you said work was going well".
After a big gulp of wine, Lou leans back and says "Work is fine, I'm just fed up with blokes. The ones I've been out with recently have been terrible. It's alright for you. You have Dan. I bet your getting fucked every night. I've not fucked in weeks."
Jess laughs. "Actually I've not had sex in weeks either. Not proper sex at least. We've been trying out this chastity thing that Dan wanted to do. His cock is locked in a cage." She rummages in here purse and pulls out a little key. "This little thing keeps him trapped and horny."
Looking confused, Lou replies "Oh my god. I didn't know Dan was such a loser. I'm sorry.", then she giggles, "I guess he deserves to be locked up". Lou pauses, thinks a bit then says "but if he's locked up how do you get off."
"That's the fun part", Jess smiles, "he's so horny that he eats my pussy every day. If I open my legs, he's there in seconds and licking me out. He's not great a fucking but he's got a good tongue on him." her cheeks go red, maybe she shouldn't have shared this much.
"So much you've been getting lots of tongue action every day and I've been here getting nothing". Her face becomes mischievous and she eyes the key. "is that the only key to Dan's cage?"
Jess is unsure why she's being asked the question but answers anyway. "He threw away the spares. He said he wanted me to have the only key. I really don't understand it. I'm not domme. But it makes him happy and my pussy gets more action now than before so I guess its a good thing. In fact he's due to be let out tomorrow. We're going to fuck for the first time in weeks."
In a flash, Lou grabs the key off her and holds a it behind her back. Laughing she says "I guess you can't fuck him now. If I'm not getting fucked then neither can you."
"Give it back Lou. He really will be stuck in that thing without the key and he's already been locked up for weeks. He's absolutely gagging".
"I'm gagging too Jess, so fairs fair. If you want him to get out of that cage and fuck you then I need to be satisfied first."
"What?" Jess looked confused, and then Lou stood up, hike up her dress and pull off her black thong.
"Lie on the floor" she ordered. Jess hesitated "Lie on the floor now or dan will never get unlocked."
Jess slowly rose from the sofa and lay on the floor. Lou stood over her head facing Jess's feet. "If you make me cum then, I'll give you the key back. It's only fair I get some tongue action too."
Lou squatted down until her shaved pussy was pressed against Jess's mouth. It took a moment but then Lou could feel Jess's tongue one out and start licking. Slowly at first but then faster and faster.
Lou moaned. She rubbed her pussy over Jess's face as her tongue lapped at her clit. Lou's juices glistening all over Jess's face. It wasn't long before Lou could take no more and she screamed in pleasure. She pulled away, and her pussy gushed, spraying down Jess's top, and soaking her big tits.
Afterwards, Lou refused to return the key. She said that she deserved weeks of tongue action too before I'm let out. Jess was to go over there every night to lick Lou's pussy. She even invited me to come along too. Knowing that I'd just get even more horny and desperately want out of my cage. She knew she could take advantage of that.

Well now I'm fucking horny. I look forward to rereading this later and having a good jerk.
