Open the box

The box was pretty big. It came up to my waist and was about the same width and depth. So far nobody had voiced any concerns about how it came to be in the middle of our living room while we had been away on holiday. We hadn't asked anyone to watch over the house while we were away.

Kirsty fetched a pair of scissors from the kitchen and handed them to me. I held them open and scored the brown tape that ran along the top of the box. On the first attempt, the scissor blade didn't go all the way through but my second attempt split the tape and we were able to open the cardboard flaps and peer inside.

The first thing we saw were four envelopes, one addressed to each of us. Beneath them, a plain cardboard sheet hid the rest of the contents.

"I guess we should open these first," I said, handing the envelopes round to my naked family. James took his, then I offered Lucy hers. She farted again, and the hand that was about to take her envelope swiftly moved down to her pussy and started rubbing.

"Oh, that feels so good," she cooed. Next to her, James was stroking his hardening cock and staring lustfully at his sister. My own dick was also getting hard, and Kirsty stood next to me, stroking it with one hand and cupping one of my buttocks in the other.

"Mmmm, what lovely, sexy, horny children we have," she observed, as we watched James and Lucy embrace - a long, slow, lingering kiss on the lips. James dropped his envelope to the floor.

"I don't think I'm going to get around to reading that lot any time soon," he said, moving in to kiss his sister again.

"W-whoa, wait," stammered Lucy. "Hold on, big boy. I want to find out why... why I..." she looked down at her brother's stiff penis, a one-eyed monster staring right back at her. "Oh, I want your cock so much," finished Lucy, kneeling down to engulf James's penis between her supersized breasts.

"Yeah, ok, stop, stop stop!" I intervened. "Lucy's right, we can't just screw each other silly all night."

"Oh, can't we?" asked Kirsty in her best slutty, sultry voice.

"Well, maybe later," I conceded with a smile. "But the kids deserve to know what's going on - and I want to see what else is in the box too. And we still have work and college tomorrow."

"Well I can't do any reading while I have a massive hard-on and I'm sharing the room with four massive tits on two sex-hungry nympho women!" protested James.

"Right, so, you two go to your rooms. We'll split up, read our stuff, then get back together to unpack the box."

"And our stuff from our holidays," added Kirsty.

"Ok, Daddy-dear," gushed Lucy, all sweetness and light, wobbling her boobs at me and pecking me on the cheek before heading upstairs with her envelope. James followed immediately behind.

"Yeah, wobble that arse for me, sis," he said as he followed her up the stairs.

"Well, that leaves the two of us alone," observed Kirsty, turning towards me and pressing her tits against my chest. My hands instinctively reached down and cupped her buttocks, and she did likewise as our lips met and we snogged passionately.

"Yes, it does," I replied. "I think we should..."
