Susan and I were sitting in the living room with her parents when they suggested Susan go down to the basement and grab some snacks off the storage shelves. Susan grabbed my hand and said, "Come help me pick something."
As I walked down the stairs behind her, I watched her shapely ass wiggle. My constant battle to keep my hands off her was once again lost as I reached out and grabbed her sexy butt. Ignoring me, she kept walking across the basement to the pantry stocked with enough food to rival a small grocery store. My eyes were locked on her tush the entire time. Susan started browsing the vast selection of snacks her parents kept on the shelves as I came up behind her and put my arms around her, nuzzling her neck through her long blond hair.
She grinned and said, "You're not being helpful."
As I brought my hands up to her wonderful B-cup tits, I pulled myself in close so that my already stiff penis was pressed against her lovely derrière. Through her shirt and bra, I could feel her nipples eagerly responding. Pulling her hair back, I kissed her neck and ear, enjoying the softness of her skin and the fresh scent of her recently washed locks. I moved my hands down to her hips, pulling her tighter against me.
"What if one of my parents comes down?" she asked.
"Don't worry. We'll hear them on the stairs," I replied as I slipped one hand into her shirt and fondled her perky little breast, gently pinching her receptive nipple. As I slipped my other hand into the top of her jeans, she sucked in her already flat, smooth belly to give me easier access. My hand found its way into her jeans and panties, through her soft bush, and into her already soaking wet pussy.
"You're bold," she moaned.
"You don't seem to mind," I replied. "I'm not the only one that seems a bit horny."
I removed my hand from her breast and reached down, unbuttoning and unzipping her pants while continuing to finger her and rub her clit hood and mound with the palm of my hand.
"What are you doing? Come on. We're gonna get caught," she whispered.
"Don't worry. They sent you down because they don't want to leave the sofa." I slid my hand out of her pants, leaving a wet trail up through her sexy pubes, and set about unbuttoning and unzipping my own pants. I pulled them down enough for my erection to spring free. Without pause I wrestled her tight pants down and positioned myself behind her, pressing my rigid leaking cock against the crack of her beautiful butt, leaving a wet spot where the tip contacted her. I slid my stiff member up and down between her cheeks a few times.
