Chapter 4

Over the next few weeks, even if we were doing something regular together like watching movies or doing the dishes, if I looked at her a certain way or if (when we were alone) we kissed deeply enough, she would take my hand and haul me off somewhere—once, simply to the pantry, where we did it standing up in less than five minutes; our first quickie. We had sex every day at least once, even when her period came. We just did it in the shower.

It was Nat who said it first—moaned it first, really, and maybe she really said it because she thought it was true, I don’t know.

Mum was at work, and it was a Saturday, several days after Nat had finished her period. We’d gotten into the recent habit of putting on records when we fucked; they gave a nice tempo a lot of the time, and if Mum was home and we wanted to sneak one in, they covered up sounds pretty well. Nat’s favourite to ride me to was ‘Misty Mountain Hop,’ from Led Zeppelin IV, and it was playing today. Our favourite thing to do while our mother was working was, inevitably, to fuck each other. Today we were taking our time; lying tangled up in my bed covers, kissing, our hands lazy but lustful. Her lips were soft and swollen; she’d been sucking on my cock a few minutes earlier, and had been getting very good at it, too.

Her teeth caught my lower lip as she squeezed my erection, eliciting a moan from me. I knew she enjoyed that, hearing my moans of enjoyment at things she did. My hand crept to her breast and I pinched her nipple gently, savouring the way my sister whimpered and squirmed against me at my touch. She was only wearing a pair of cotton panties, and I pushed them down her legs. Nat kicked them all the way off and then moved to straddle me, rising up on her knees before sliding down onto my waiting cock. I couldn’t help but moan as her pussy swallowed my aching penis whole.

She began to ride me firmly but slowly, with quick, hard thrusts, whimpering as my hands reached up to cup her bouncing breasts. I spread my legs farther so she could take me deeper, hands now going to her hips to urge her movements on. But I couldn’t take it much longer; I wanted to get on top of her and fuck her silly.

Nat seemed to feel the same, because she pushed onto me deeply one more time, lustily, and then gasped out, ‘I want to feel you on top of me, Trevor.’

We rearranged ourselves. Natalia lay on her back, and I gently kneed her legs farther apart to accommodate me, sliding my swollen cock inside my sister slowly, watching it disappear with a moan. I began slow but picked up the pace, eager to watch her face, how she flushed and moaned, squirming and struggling beneath me. She was close to orgasm when she said it, I could feel it; I had one hand between her legs and was rubbing a spot she showed me with my thumb.

‘Oh, fuck,’ she moaned, which only made me harder and begin to pound her more vigorously—when she cursed it was a big turn on for me. ‘Trevor, you’re going to make me pregnant one of these days,’ Nat gasped.
