Sister’s underwear picture message – Chapter 3

I gave her a sloppy kiss on her pussy lips before mounting the bed and straddling her stomach. She grabbed a breast in either hand and squeezed them together leaving me in no doubt where I was to put my rock-hard erection.

Pressing myself between her globes, she smiled up at me as she allowed easy access before I felt her flesh envelope me in a tight embrace. She then leaned forward and gave the end a quick suck as it was now sticking out near her chin, which added saliva to the natural pre-cum that was already escaping the end.

“Just a little help,” she said, referring to the extra spit now on my cock. “Now just gently rock” she ordered.

I once more did as instructed and within seconds had got into a nice rhythm as my cock slid between her tits poking its head out from between with each forward thrust. It looked a little comical for a start and I found myself almost laughing out loud as the head kept popping out from between and then disappearing from view like a tortoises head going in and out of its shell.

“That’s it Steven, fuck my tits” she said whilst giving her own nipples a pinch.

I pumped away, twisting myself slightly and reaching behind, blindly feeling for her sex which met with a gasp from Chrissie when I touched it. My palm rested on her pussy mound as my fingers slid between her slick lips before I pushed two in as deep as I could.

Now her smile had faded to a look of determination as I started to pump the digits into her building her pleasure towards a climax. I exchanged her hand on her boob to my own so I was now kneading her breast at the front, pressing against the other still with my cock between whilst fingering her cunt from behind as I still slid effortlessly between the softness of her globes.

“You’re gonna make me cum!” she said, her eyes half closed with pleasure, to which I replied “snap”.

“Harder!” she ordered, my fingers now squelching deep inside her as I thrust against her body both in and out. “Make me cum” she said again, her bottom half lifting slightly as if to both encourage me to go as deep as I could whilst also rocking me back and forth between her tits.

“Ahh shit Steven, I’m coming!” she said, her eyes now closing fully as I felt her muscles contract around my fingers whilst shallow breaths indicated her impending climax.

“Oh fuck, me too!” I said as the first shot of spunk erupted from the end of my dick onto her neck.

‘Ooh’s’ and ‘aah’s’ escaped from both of our lips as we rocked and twisted using hands, fingers, tits and whatever else as our fluids erupted in a mutual orgasm until we slowed to a point where I pulled my sticky fingers from her hole as our hands released her breasts which in turn allowed my softening erection some air.

I pulled a face as an apology to the mess I had made on her chest, although thankful it wasn’t the first ejaculation of the day meaning at least there was a little less of it. But Chrissie didn’t seem to care in the slightest, lifting her hands to rub in the gunk as if it was moisturiser!

“I think that’s enough for one day little brother, don’t you?” she asked as I ‘unstuck’ myself from her, un-straddling myself from her.

“I don’t think I’ll ever have enough of you Chrissie” I said, grabbing some tissues and handing them to her.

There was then silence in the room, and we heard no sounds from our parents room either as we looked at each other hesitantly, even holding our breaths.

“Do you think….?” I mouthed silently to Chrissie.

She shook her head, dismissing the idea that they had heard anything. “They’re probably both fast asleep now” she whispered, looking at my bedside clock and wiping away the last of my cum from her tits.

“You really are incredible Chrissie” I said admiring her killer body as she pulled on her shirt, picking up her knickers but just carrying them.

“And you’re pretty good yourself,” she replied nodding towards my limp dick.

“I suppose you want me to delete those pictures now?” I asked.

“To be honest Steven, I don’t really care as long as they remain part of our little secret.”

I raised an eyebrow, nodding profusely and confirming that they would be shown to no-one, ever.

She then raised her phone and took a full frontal picture of me catching me by surprise.

“Well now I have one of you naked as an insurance too!” she said with a little laugh.

I looked annoyed. “You could have at least took that earlier when I was a little ‘bigger’!” I said giving my flaccid cock a rub.

Chrissie just shrugged her shoulders. “Well I might just have to do that another day then!” she added before giving me a kiss on the cheek and disappearing from my room with the stealth of a ninja.
