A test for Bibi

A few days later Murcy tells Bibi that Sue will be coming by with a friend, and they have a test for her.

Bibi expects more lesbian activities to be in store, but when Sue arrives, Bibi is surprised to see that the friend is a guy named Logan.

"Ok, let's gets down to business", Murcy says, exposing her tits. "Todays challenge is to make Logan cum, and the slut who makes him cum is the winner". With this she starts to pull off Logan's clothes.

Bibi decides to be slutty too, and pulls down Sue's dress and start massaging her tits. Murcy has got her hand on Logan's cock, and strokes it to ensure he's hard, which doesn't take long.

Murcy then gets between Logan's legs and start licking his balls. Sue and Bibi joins in and soon they are licking his shaft. Bibi can hardly remember the last time she even saw a real hard cock, so she enjoys it fully, and sharing the cock with the other girls seems completely natural to her now.

Logan sits on the couch, and Sue is first to mount his cock and starts riding him cowgirl style. Bibi leans in to to give Murcy a kiss.

Sue rides Logan's cock hard, intending to make him cum, but soon her own orgasm overwhelms her, and Logan push her off his cock. "Next" he says. Bibi realizes that while most men she ever knew would have cum already, Logan seems to have the sexual endurance of a real male pornstar.

Murcy reacts fastest and takes Sue's place as she starts riding Logan's cock in reverse cowgirl.

Murcy too tries to make him cum as she rides him hard, but soon she too must surrender to her own orgasm, and she rolls off his cock.

This times Bibi doesn't hesitate. It's been a long time since she had a cock in her, and she's never fucked bareback with a stranger before, but the pill Murcy gave her, and her practice with her dildos has given her confidence. She mounts Logan's cock, and lines up the tip, with her wet pussy, but then she gets an idea. Logan grabs her ass cheeks as he's impatient to get inside her. Bibi quickly adjusts herself so that as Logan thrusts upwards, his cock slides into her ass, rather than her pussy as he had expected. Logan lets out a moan at the sensation as he penetrates her tight ass.

Bibi keeps riding Logan's cock with her ass, and she feels him twitching just before the feeling of his cock spilling its seed deep inside her tight ass. Logan pushes her off him, and she lies down on her side on the sofa as she feels his sperm starting to leak out of her ass. Sue quickly puts her head under Logan's cock as it pops out of Bibi's ass, and Sue hungrily licks up the last drops of cum dripping from his cock.

"And the winner is... Bibi", Murcy declares as Sue cleans up Logan's cock.

Then Logan gets dressed, and leaves.

The three girls sits for a talk.

"Congratulations Bibi, you have taken another step towards becoming a true slut" Murcy says.

"Thanks, it was amazing, I never had a guy cum in my ass before, and I really loved it!" Bibi says in honest. "What more would I need to do to become a real slut?" she asks.

Murcy replies, "You did great today Bibi, but it was all set up by Sue... she brought Logan, and he knew that he would be fucking us. Real sluts finds their own fun. I'll accept you as a real slut the day you've on your own initiative fucked a stranger and let him cum wherever he please", Murcy finishes.

Bibi giggles at that, "Fair enough, got your point", she says.

Sue looks at Bibi and says, "I have a porn shoot on Friday, would you like to come and watch?".

"I would love that!" Bibi replies.

"Great, I'll send you the details once I know the time and location" Sue says.

After that they small talk for a while before calling it a day.
