"Mmm...fuuuck!" Jack was unable not to vocalise his second orgasm. Fighting the instinct to bury himself deep, he left only the head of his dick inside her ass as he came; he knew it wouldn't be a big load, but he wanted to watch it escape from her ass like his first had dripped from her pussy. When his cock ceased pulsing, he removed it, savouring the pull as his flared head popped free of her sphincter. Her anus remained open, twitching, but barely closing a millimetre, so used to having first the plug and then his cock holding it open. Moments later, the first trickle of semen emerged, seeping over the rim and beginning a slow journey down towards the bed. Reaching out, Jack ran a finger tip around the circumference of her open asshole, then, inspired by that same kinky side that first responded to Elle's post, inserted two fingers into her, confirming that they no longer touched the sides.
Withdrawing his fingers - Elle still oblivious to their presence inside her - he said, "You can let go now."
Elle released her grip on her knees and lowered her feet back down to the bed.
"You can take off the blindfold too."
She did, stopping short of pulling it off entirely, leaving it over her forehead.
"Will you take this out of me?" Jack asked.
Elle nodded and indicated that he should turn around, which he did, remaining on his hands and knees and presenting her with his backside. Slowly, she fought her protesting muscles and sat up. Sliding her fingers between the base of the plug and his backside, she pulled gently. Jack's hole, still clamped down after two orgasms, put up a valiant fight, but ultimately succumbed. The large plug popped free, eliciting a grunt from Jack. Unprepared for its swift emergence, Elle lost her grip of the slick glass and it fell to the bed. She ignored it, staring instead at his hole as it slowly closed.
"How do you feel?" she asked as he turned around to face her.
"Pffff," came Jack's reply as he settled down cross-legged on the bed, "I'm not sure I can describe it. I've never cum twice in one go before. You?"
"Well fucked," Elle replied after considering for a few moments. Then she asked, "Actually, I think I need to see something."
She turned, searching for something on the bed beside them. She found it lying behind her, the plug that until recently had been locked inside her ass.
"I want to see how big this got inside me." She held the base of the black plug in her left hand and the squeeze bulb in her right, connecting tube dangling in an arc between the two. She squeezed once, watching as the plug increased in size a tiny amount. "How many times did you pump it?"
"I can't remember. Maybe seven?"
Elle squeezed the bulb six more times in quick succession. When she stopped, the plug was unrecognisable. What before looked like any other regular, slim butt plug now more closely resembled a black globe. It was almost perfectly spherical, apart from the stem connecting it to the base in Elle's hand, and roughly the size - to Elle's eye - of a large grapefruit, or a small melon.
"Holy shit, no wonder I felt full!"
"Yeah, I could feel it inside you," Jack said, staring at the inflated plug as Elle found the release valve and it returned, hissing, to its regular size.
"I felt that too," said Elle. "How did you like yours?"
Jack considered for a moment, his face screwing up as he searched for a way to describe what he'd felt. "It hurt at first," he said finally, "but once it was in it felt...good. Really good actually." His cheeks flushed as he continued, "And it felt amazing when I came. Like it...supercharged everything."
"I'll keep that in mind for next time," Elle grinned, glancing down at the glass plug lying beside Jack's hip. "Speaking of which actually." Her head perked up like she'd just remembered something. "I have an idea for next time."
"Oh really?" Jack asked, feigning hesitation and wariness.
"Yes, but it will be better if we spend the weekend together and....I'm not sure with Jenn around..."
Jack figured what she was trying to ask without asking and cut her off. "Come stay over here for the weekend then. Much less chance of being interrupted," he grinned.
"Really?" Elle asked excitedly. "Great! There's just one thing though." She paused, waiting for Jack to say something. When he didn't, beyond simply raising his eyebrows like he couldn't believe she'd ask for something more, she continued carefully, watching his reaction to each word, "You can't touch yourself. Your...penis I mean." Jack's eyes went wide as she said that. "For the whole week."
"The whole week?" Jack asked in disbelief. "You want me to not touch my dick for a week? What about going to the toilet?"
"You can just sit down. I'm sure it's possible. Just trust me," she added when Jack began to shake his head, "it'll be worth it. Just try not to touch it and definitely no...playing with it." The cheeky smile returned to her face as her mind conjured up an image of Jack trying desperately not to masturbate his stiff prick.
"Okay," Jack finally agreed, shaking his head slowly, looking resigned to whatever fate Elle had planned for him, "I'll try." It wasn't going to be easy though. Nevermind pissing, he couldn't remember the last time he'd gone longer than three days without wanking.
"Trust me," Elle repeated, sliding off the bed in search of her underwear.
