Chapter 5

It was a glorious orgasm for both of us. We stayed in bed for a while and cuddled. I think I fell asleep for some time, and I woke up as Martine stirred.

“I’m getting quite cold and feel sticky. I need a shower.” She stated as her smiling face looked at me.

“I need a shower too. Do you think we can share?”

“What a great idea.” Martine accepted as her smile widened. As she got up, still naked, she headed out of the room.

I quickly caught up to her and hugged her from behind as we walked in tandem towards the bathroom, with my reviving cock pressed against Martine’s round ass and nestled in her crack.

“Hmm ... I like this,” She said as she put her hands on top of mine as they covered her tits.

“I love the feel of your body against mine,” I replied as we reached the bathroom.

Stepping near the bathtub, Martine suddenly started bending over, reaching for something on the floor.

“I’m such a slob. I left my panties on the floor.” She said and giggled.

With my hands pulled away from her tits, and her body bending down in half, my cock was suddenly pressed against Martine’s crotch. I couldn’t help myself and grabbed her hips and ground my cock against her wet lips.

“Oh,” exclaimed Martine, as she held her position.

I didn’t dare do more than rub my cock against her crotch. I desperately wanted to just shove my cock into her enticing wet hole as her fat pussy lips cradled my cock like a hairy hotdog bun, but I didn’t dare take this step on my own. I wasn’t sure if Martine was open to that or not just yet. Although she was making it really hard on me to respect whatever boundaries she may have in her mind, her actions and staying bent over the way she was, didn’t exactly message ‘I don’t want this’. Since I knew how babies were made, and I was absolutely sure that I would blow my load as soon as my cock was fully embedded inside my sister’s lovely tunnel, I didn’t want to risk an unwanted mishap so I just kept humping her crotch and not taken the ultimate step.

I guess Martine shared some of my concerns and after many long delicious seconds of enjoying this contact between our genitals, she started straightening up.

“I think we should stop this before we do something stupid.” She said sighing.

“I don’t want to stop, but I think you’re right.” I replied with the same kind of I-don’t-really-want-to tone.

“Come, let’s take a shower and clean up.” Martine finally said, pulling her ass away from my disappointed cock. Strings of pre-cum, mine and hers stretched between us as she slowly moved away. It was as if our genitals were desperate to keep contact and pulling at each other.

Alas, it had to be done, so I stayed back and let the strings be broken as Martine stepped into the tub.

I stepped in behind her and watched her ass as she turned on the water and put her foot under the faucet, waiting for the water to warm up.

Soon enough, Martine switched the water to the shower head and stepped under it. I grabbed the soap bar from the soap dish and got closer.

I started running the soap on her back in order to help her wash.

“Oh, nice, I’ve never been washed by somebody else since I started taking showers on my own when I was a little girl.”

“I’ll wash you whenever you want.” I simply replied.

“I’m so happy to have you in my life. You make me feel so good.” Martine said as my hands reached her front and started soaping her fat tits.

I soaped and soaped, and of course, I couldn’t keep my hands from my now favorite place, Martine’s crotch.

Soon enough, my fingers were rubbing the slick groove and concentrating on her clit.

Martine’s legs spread as far as the tub allowed, giving me as much room as I needed to make her feel good.

Of course, being in this position behind my sister, I couldn’t help pull her back to me and rub my painfully hard cock between her asscheeks. Martine simply leaned back against me and leaned her head on my shoulder and simply enjoyed herself.

After a while, I did what came naturally and pushed my cock down and slipped it between her legs and started slowly fucking her thighs. My cock was hard enough that it was pointed up and basically was trying on its own to find her hole. Martine didn’t resist or show any concern over my cock’s position or its attempts at gaining access to her most treasured asset.

And while I enjoyed myself, and really wanted to gain such access, I kept myself in check. Her previous note about ‘something stupid’ kept my mind alert, as it meant she was concerned about getting pregnant.

At one point, my cock’s head caught on her hole’s rim and pushed hard against it, but as Martine must have been tight, it didn’t get in, and snapped out and pushed against my fingers that were busy rubbing her clit.

A minute later, my cock caught the rim again, but this time it seemed to trigger Martine’s orgasm, and squeezed her ass, and pushed her belly forward, seeking more contact between her clit and my fingers, thankfully pulling away from my cock and from whatever disaster that would have led to.

Martine didn’t pull away completely from my cock, but just enough that there was no risk of penetrating her pussy anymore.

As I was busy making sure to maximize her orgasm, I was suddenly aware of a new sensation.
