“May you…?” I trailed off as stepping up behind her; Steve pulled his once again hard cock from his pants.
He lifted Mary’s skirt, flipping it over her ass and grabbing her hips he smiled at me, “May we join you?”
“Yes.” Alicia said quickly “I want to watch!”
Where that had come from I had no idea, but Steve did not need to be told twice. Placing his cock between her legs he shoved forward and Mary moaned in pleasure. The look on what part of her face I could see caused me to remember my cock was still buried in Alicia’s pussy and as Steve started fucking Mary fat and hard I joined him. Alicia began yelping as I put all the power of my hips into my thrusts and Steve looked like he was doing everything he could to match me.
Sliding her hands forward on the bed, Mary took Alicia’s in hers and the two of them held hands as Steve and I pounded away on them. That sight caused me to gasp and I could feel my legs trembling as I began to get close.
“You are so beautiful!” Mary gasped as her husband fucked the shit out of her, “Both of you! So hot, so perfect!”
“Oh yeah,” Steve moaned sounding as if he were getting as close as I was. “Better than we ever dreamed! Look at the two of you fucking, I…oh fuck Mary!”
Steve gave Mary a couple of more pumps that were nothing short of vicious and whipped his cock out. Mary rolled over and sitting up turned her head so we could watch Steve spray his cum directly into her wide open mouth. She caught some but a lot splattered on her chin and dripped down onto her shirt. The sight sent me over the edge and squeezing Alicia’s hips so hard she cried out I slammed her several more times before whipping my own cock out.
Like Mary, Alicia rolled over, but staying on her back held her tits up for me. I had initially thought I would get my wish of using her tattoo as target practice, but the sight of my sister presenting her tits to me was even better. Leaning over I pumped my cock and called out her name as my cock erupted sending several long thick spurts across both her tits. I kept pumping my cock moving it back and forth, making a show of painting my sister’s gorgeous tits. When I could coax no more from my spent cock, I moaned softly and all but fell onto the bed next to Alicia.
We remained silent and the room was filled with all four of us breathing hard. I watched Alicia’s cum covered tits heave and then looking at her sweat slicked face couldn’t stop thinking about how hot she was. She saw me looking and gave me a tired smile. Despite the dirtiness of the situation I felt an overwhelming wave of affection for my sister and leaning over kissed her softy on the lips, “You’re beautiful sis.” I told her.
“So are you Andy,” taking my hand she squeezed it, “So are you.”
“Now that is almost as good as the sex.” Mary murmured.
“Almost.” Steve laughed. Getting up he grabbed a pile of towels that was on the floor next to the bed and after handing me one started wiping the cum from Mary’s face.
Following his lead, I gently wiped off Alicia’s tits. Mary got up from the bed and going over to the small fridge came back with four bottles of water. We all drank deeply and after finishing mine I stood up and now feeling a bit self conscious pulled my jeans on and handed Alicia her dress. Alicia stood up, groaning with the effort and after slipping her dress on leaned over and bean putting her sandals on.
