We're going to go back up there, and we're going to try and make a baby for Margaret!"Em was huddled under the duvet weeping; so tense I could hardly ...ouch her. I took Mark out onto the landing."Mark sweetie, could you find some things to tie Margaret's wrists with, scarves or ties would do, and some lube, not Vaseline if possible, anything water based, like KY," I whispered in his ear. "I need to lay some groundwork. I'll call you when she's ready."When he'd gone, I reached behind Em's neck. I had not even assumed I would let him fuck me but Sara had decided it was a done act, and as my thighs were open she reached down and pushed her brothers cock into me, then watched as we fucked, she pushing her brother back into me each time his pulled his cock out.I could feel his urgency build as he was on the point of release, Sara slipped on top of him and put her weight onto his bum, she rode his ass until he came inside me, her weight not allowing him to pull from me, we kissed as he. He started the car and aimed it towards the estate's gates, no real idea of where he was going just that he needed to get away for a while.As Kenny disappeared down the drive, two plainclothes policemen emerged from the woods that surrounded the house and raced across the lawns to the front door. Finding it open, they entered to see what they could find."You take upstairs and I'll see what I can find down here," the taller of the two said."How long do you think we've got?" his partner. Grind your hips against me. Watch as I play with my tits, pulling my head up to take a nipple into my mouth... Sucking... nibbling... biting...As your cock slides harder, deeper into my hot pussy so wet now... so wet and hot... sucking your cock into me. Squeezing around your thrusting cock... as you fuck me deeper... Groaning with each thrust...I'm watching you, watching as you show me just how good you can take care of that throbbing rod...God how I love watching you...Seeing you get yourself.
