Night classes

We all ate breakfast and were soon out in the snow again. Paige and I caught up with our parents for lunch and hung around with them and their friends for a few hours. I called it an early day after that and went back to the house to read my book.

That night after dinner, we all stripped naked and made our way out to the spa. Before I could even sit down, Melissa had her mouth on my cock and was sucking away. Paige sat down next to me and I couldn't look away from her free hanging tits as they lowered into the water. I reached over to her on my left with my right hand and grabbed her right breast in my hand as I settled into the water, resting my shoulders on the edge and holding my crotch up to water level so Melissa could continue sucking.

Despite what had happened the night before, and how nonchalantly she was taking it, I still felt my throat close up slightly in anticipation of a recoil from Paige. My fear quickly subsided as my sister moaned softly instead of slapping me. I quickly lifted my left arm out of the water and put it around her neck, reaching down the other side to take hold of her other large breast.

As I groped and kneaded my sister's melons, Melissa worked my cock with her mouth. She was quickly replaced by Amanda, then Dawn and finally Kara before the cycle restarted. They each took turns sucking me off for a while until Paige spoke.

"Okay girls, back off for a bit. I'll show you how it's done."

She didn't have to tell them twice. They all moved back into their seats as I released my sister's tits and she moved into position between my legs as I moved back and sat on the edge of the spa. Then for the second time in two days, my sister lowered her mouth over my member and sucked me into her warm mouth. Her tongue darted all over my cock shaft as she applied suction.

My sister quickly settled into a slow rhythm on my cock. As she did so, Dawn lifted herself out of the spa and onto the edge, spreading her legs as she perched there.
