Jack, the Virile Stud Breeds His Family (Incest)

I was finally heading home from college for the summer break. After a brutal year of constant studying, papers, and exams, I couldn't wait to just relax for a while. The drive was long but worth it - three solid months of freedom stretched ahead of me from late May until mid-August.

As I pulled onto my street, I thought about my family waiting for me. Mom, Karen, was forty and still attractive despite what she called her "mom body." She stood about 5'7" with shoulder-length brown hair and curves in all the right places. I knew her bra size was 36D because I'd been in charge of laundry when I lived at home. My twin sisters got stuck with dishes and cleaning.

Dad, Tom, was fifty - ten years older than Mom. He worked as an electrical engineer and was a big guy, about 6'2" and around 260 pounds. He and I never had the closest relationship. While Mom came to every game and school event, Dad always seemed to have something more important going on. He wasn't a bad father - just distant. He made good money and provided well for us, but emotional connection wasn't his strong suit.

My twin sisters, Stacey and Jessie, were freshmen in college. They weren't identical, but people often got them confused. Both stood around 5'4" with dirty blonde hair. Neither was skinny, but they weren't overweight either - just naturally curvy with nice asses and perky tits. They hit the gym regularly, and I'd caught glimpses of them by the pool last time I was home. I couldn't deny having had some impure thoughts about them in their bikinis.

As I pulled up to the house, I noticed three cars in the driveway. That was odd - Mom and Dad shared one car, and my sisters shared another for college. Who did the third car belong to?

I had to park on the street since the driveway was full. Grabbing my bag, I headed to the front door. Before I could knock, it swung open to reveal my grandmother Beth standing there.

Beth was Mom's mother, but she barely looked fifty though she was fifty-six. She'd had Mom when she was only sixteen. Beth was petite, maybe 5'2", with blonde hair that fell to her shoulders. She kept herself in amazing shape, her body tight and toned. Today she wore a tight tank top with thin straps that showed off her bra straps, and yoga pants that hugged her perfect ass.

"Jack!" she exclaimed, stepping forward to hug me.

As she pressed against me, I felt my cock stir. Shit. I hoped she wouldn't notice, but she squeezed me tight, pressing her tits against my chest. When she kissed my cheek, her lips lingered a bit too long.

"It's so good to see you," she said, looking me up and down. "You've grown into quite the man. Unlike your father, you clearly take care of yourself."

"Thanks, Grandma," I said, trying to adjust myself discreetly. "I didn't expect to see you here. Where's everyone else?"

"I'm staying for about six weeks while my condo gets renovated," she explained. "Your mom was kind enough to let me stay rather than waste money on a hotel. And now I get to see my handsome grandson every day! Come in, everyone's about to have dinner. We didn't expect you until later."

I followed her into the house, watching her ass sway in those yoga pants. I felt guilty for checking out my own grandmother, but damn, she looked good.

The family was gathered around the dining table - Dad at the head, Mom on his left, my sisters on his right. I sat next to Mom, and Grandma Beth took the seat at the other end opposite Dad.

Dinner was Mom's usual excellent cooking - salad, meatloaf, mashed potatoes, green beans, and cheesecake for dessert. We caught up on college stuff, and then the inevitable question came.

"So, Jack, any girlfriend?" Mom asked.

I shook my head. "No time with all my classes. Maybe next year."

My sisters exchanged smirks, and Grandma Beth chimed in: "I'm shocked! A young stud like you must have girls throwing themselves at you."

"I'm focusing on my degree first," I replied, feeling my cheeks flush. "Plenty of time for dating later."

"If I were your age," Grandma Beth said with a strange smile, "I'd be chasing after you. You're quite the catch. Stacey, Jessie, wouldn't you agree your...
