I turned 18 just before our Spring Break in 1994. In those days, Spring Break was not the whole week that seemed to match up with a lot of the colleges in the country, but usually the Friday and Monday around the Easter holiday. These were also the days before cell phones and even the Internet, so much of our family communication revolved around the dining room table or the phone in the kitchen.

Our home was ultra-conservative religious. Dating was restricted; no parties where boys were present, and I never once went to a slumber party. Bible study every night, prayers at dinner, religious youth group activities every week, and lights out by 10. I held a boy's hand once, and even snuck a kiss with him, but we never went out on a date, nor did we ever go further. Many of my friends did, which was why my parents were so strict about my rules. They wanted to keep me pure for my future husband.

It even went so far that my room was downstairs in the basement while my brothers, two older brothers and two younger twin brothers, lived in two bedrooms upstairs across from my parents. They couldn't risk me even seeing my own brothers' skin. And iftheysaw me in even my underwear, my dad's head would probably explode.

When my oldest brother, Gary, went to college, he stayed close to home, only moving out when he found a job in a different city and had to move. Steve, however, decided to go to a school halfway across the country, finally getting out from under our parents' strict rules. If he rebelled against our parents' strictures while he was away, we never found out. Or at least my parents never did.

When he brought his fiancée home that Spring Break, though... I learned quite a bit about my brother.

He called us in February and announced he was engaged, and that he would bring her home to meet everyone over Easter. My parents were thrilled, of course, since he was engaged to, as he put it, "A nice girl who comes from a fine, traditional family from Nebraska." Of course, one of their first questions was about her church-going activities, to which Steve was able to placate them. They were so excited he was marrying such a "good girl."

Naturally, Steve would stay in his own room across from Mom and Dad, which meant that Shannon, his fiancée, would have to bunk in with me. I had a larger, double bed, plus with Shannon being in the same room with me meant that neither she nor Steve could sneak away to "sin."

Shannon was a complete bombshell, in spite of her attempts to look modest for my parents. Her t-shirt was stretched to almost its limit across her ample breasts, and her jeans, fit tightly around her curved hips and rounded behind. Her face was model material with her strong cheeks, smooth skin, piercing blue eyes, and blond wavy hair. She was gorgeous, and I had to close my mouth quickly to keep my jaw from hanging open from just looking at her.

That should have been my first indicator regarding my own sexual inclination. Looking at Shannon... and all I wanted was to hold her close, feel her body against mine, touch her soft skin, run my fingers through her thick hair. There was no explanation for it. Physically... I just wanted her. I didn't understand the ins and outs of sapphic love, but the need to simply touch her was nearly overpowering.

However, I kept our introduction to a simple handshake, and I led her to my room where she would be staying.

"Do you mind sharing the bed?" I asked timidly. "Cuz if you do, I'll sleep on the floor."

"I don't mind at all, honey," she replied with a sweet smile, as her eyes glanced up and down my body, and my skin buzzed with an electric intensity just from her scrutiny. Her smile widened and her eyes flashed, as she said, "It will give us a chance to really get to know each other."

The way she said that made my stomach inexplicably lurch, and I watched her walk out of the room with an enticing sway to her hips... and I could not take my eyes off her backside as she walked. As she reached the stairs, she looked back and caught me looking. She smiled sardonically and headed up to dinner.

I had no idea what was going on with me. Why was I looking at another woman's body with such... curiosity... desire? Of course, I had heard numerous discourses against the sin of homosexuality and lesbianism, so I knew that what I was experiencing was the enticement of evil. I walked upstairs wondering why Hell sent such a temptress to me... and why I wanted her so badly.

Dinner was small talk, getting to know Shannon, how they got engaged, what their plans were, etc. She, Steve, and my parents did most of the talking, which left the rest of us to just listen... and watch. Watch Shannon's face flush with delight as Steve described their engagement, watch Shannon's boobs jiggle and bounce when he laughed, watch her gaze momentarily flit over to me, a look of anticipation burning in her eyes.

Being Good Friday, we went to the church to hear a special evening sermon. I rode in the back of the minivan, next to Shannon and with Steve on the other side. I was surprised to see Shannon's hand rest high on Steve's thigh, dangerously near his crotch. My eyes went wide, and I looked up at Steve who wore a wry grin and held a finger up to his lips, asking me to keep quiet.

Shannon was quietly giggling as she looked at me and slid her hand higher, coming in contact with his crotch. And that was when I noticed the bulge in Steve's jeans, a tubular ridge down the seam of his right leg which seemed to thicken and lengthen in his tight denims. Shannon stroked that bulge with her fingertips, delighting in the subtle gasps of pleasure Steve tried to conceal.

Again, I could not take my eyes of the bulge... mybrother'sbulge... mybrother's cock. That was his penis under there. It was huge as it rested long and thick against his leg. How did he ever conceal that? How did I not notice before? And why was I feeling dampness in my own crotch just thinking about it?

As I watched Shannon surreptitiously stroke Steve's member, I couldn't help but wonder what it looked like. I had helped changed the twins' diapers when we were younger, so I had seen little boys' penises before, but Steve's... was a man's dick. Oh god, I wanted to touch it, to test how thick it is, to hold its hefty weight... maybe even to... taste it.

God! What was I thinking?!?! It was my brother! It was a sin! Why did these stirrings all of a sudden begin in my body? And why the hell was I licking my lips as I stared at my brother's bulge?

Shannon noticed that too and leaned close to me to whisper in my ear. "He has a very pretty dick. Feels even better."

The dampness in my panties gushed as I gasped in shock. She and Steve... have had sex?!?

She giggled and turned to give Steve a quick peck on the cheek.

My brother, who had been watching my reaction to their... shenanigans, laughed at me, but held up a finger to his lips once more, this time indicating thathewould be silent... about my interest... in his cock.

Once more, my eyes were drawn to his thick manhood, but I tore myself away, and looked out the window, trying to think of anything but Steve's penis sliding in and out of Shannon's vagina. No... Steve's hardcockthrusting into Shannon's sweetpussy. Me holding his thick dick while he fucked her, my other hand squeezing Shannon's tits. God... what was happening???

I didn't listen to the sermon, my mind being focused on their sins... and my imagined ones. On the ride home, I forced myself to look out the window the entire drive, so I wouldn't be tempted to look... watch... want.

Once we got home, it was time to get ready for bed. A quick family prayer in the living room, and I dashed off to my room to change before Shannon could come down, throwing on my long sleep shirt and gym shorts I slept in. I was just crawling into bed when Shannon came in, closing the door behind her. I tried not to look at her, but she flopped down next to me on the bed, forcing me to look at her.

"Did you enjoy the show, Tara?" she asked, with a knowing smile. "It's okay, you know. Everyone's curious. God, Steve couldn't keep his eyes or his hands off my tits for the longest time when we first got together. Still can't half the time." She slid off the bed and began taking off her shoes and socks, undressing. "That's the problem with religious families like ours. Yours and mine. They pretend that sex doesn't exist, and that everything to do with the body is evil. Like your long pajamas, covering all of you. Here you are separate from everyone else in the house, and still, you hide your body, even from yourself."

She opened her jeans and slid out of them, and my eyes were drawn to her black, lacy, bikini panties... with no signs of a bush protruding from under the hem. Even in my full-sized granny panties, my own pubic hair poked out, but hers... did sheshave?

Shannon stopped undressing and looked at me curiously. "Do you like looking at my body, Tara?"

I gave her a small, embarrassed nod.

"And you liked looking at Steve's dick?"

Hanging my head in shame, I looked away and nodded again.

"It's okay to be interested in dicks," she explained as she grabbed the hem of her shirt and began pulling it over her head. "It's natural. You're a young, healthy woman. Why wouldn't you be interested in cock?" She dropped her shirt on the floor and stood before me in just her panties and matching bra. "It's also okay to want to look at a woman's body, too. I used to think it made me weird, or wrong, or perverted. But a woman's body is just as beautiful as a man's, I think." She held her hands behind her back, unclasped her bra, and let it slide off her shoulders to the floor. "What do you think?"

I stared at her breasts. Full and round, with areolae the size of silver dollars, and thimble-sized nipples. They hung high on her chest and swayed softly as she moved. They were beautiful. Sure, I've looked at my own boobs in the mirror after a shower. My b-cups were obviously smaller, and so were my nipples, but I still liked looking at them and holding them. Shannon's, however, were on a whole different level. Large, smooth, perfect. The kind of tits you wanted to touch, squeeze, and suck.

"I take it this is a new thing for you? Seeing another woman naked like this? Never looked in the showers of gym class? Covered yourself so others wouldn't see yours? I get it. That was me, too. Then, one day, I saw my roommate naked on accident... and she was beautiful... like you. Petite, supple... and I just wanted her. Together, we experimented with love and sex, doing to each other what we liked to do with ourselves, and we both learned we really liked it. Sex with a woman is just as fulfilling as with a man, and I've done both."

Slowly, she crawled onto my bed, looking at me in the eye the whole time. "I bet you are curious, like I was. Wondering what it would feel like to touch another woman. What it would feel like to kiss another woman. What it would feel like to have another woman touch you."

"But... s-sin," was about all I could stammer out as I pulled my blanket higher as if it would shield me from the succubus tempting me. But I didn't want to be shielded. I wanted to give in to the temptation. I wanted to touch her, to kiss her, and to feel her touch, just like she described. God, I wanted it so badly.

"Yes," she replied sitting on her haunches, her legs open giving me a view of her distinctively un-hairy gusset. "That's what the pastor said, right? But if it's such a sin... why does it feel so good? And why do we want it so badly? You and me both, Tara."

I swallowed hard, and licked my lips, my eyes unable to look anywhere but her body.

She leaned forward, slowly and deliberately, whispering, "Tara... can I kiss you?"

My first instinct was to leap out of bed and run out of the room to put as much space between me and this seductress, and at first, I thought I was moving to do just that. Instead, what I found myself doing was throwing my arms around this nearly naked woman, and engulfing her into a deep, passionate kiss.

After just a moment's hesitation, Shannon returned the kiss with a fervor I didn't know existed. I had never before had someone else's tongue in my mouth, norneededto shove mine in theirs, but with Shannon, I accepted her tongue with relish and let mine swirl and dance around hers as we kissed.

I felt a fire in my gut I had never felt before, an awakening, a desire, a lustful need. My hands went to her chest, and I squeezed her breast, moaning in pleasure at its softness, and sliding my hands around to explore every inch of her skin. She gasped when my fingers grazed her nipples, and I experimented by gently pinching and circling them between my fingers.

She giggled into my mouth at my ferocity, but didn't make any move to quench my hunger, sighing in pleasure as my fingers teased her tits. I didn't even notice her hands pulling at the hem of my night shirt until she broke the kiss long enough to pull it over my head. I raised my arms and let her undress me, then dove right back in so I could continue kissing and touching her.

A moment later, I felt Shannon's hands on my own breasts, squeezing, caressing, and pinching me, the way I was pinching her. Eventually, I started mimicking what she was doing to me, and we fell into a mirrored rhythm of teasing and pleasure.

After about five minutes of groping my brother's fiancée, I managed to get some semblance of control and broke the kiss to fall back on my bed, panting. "Shannon... I'm sorry... I don't... I don't know what..."

Shannon laughed in reply. "Don't apologize. I fucking loved it. God, you were so intense. Made me so wet, I almost came just from your hands on my tits."

I gaped at her, stunned by her language. Words like that were foreign to me. Of course, I had heard them in the halls at school, but never in my home, in my own bedroom, andneverin response to anythingIhad done. I smiled in spite of my shock and said, "Really? You... liked it?"

"Fuck yeah, Tara. It was so hot. You're so sexy, Tara. Do you know that? Look at you. Your body is incredible." Her eyes flashed with a carnal desire I had never seen before on anyone. "Good enough to eat."

I gasped. Was she suggesting... eating my... pussy? I could barely say the word, even in my mind. Oral sex? Her mouth, her tongue on my... oh God. The moisture in my crotch began dripping down into the crack of my ass.

Shannon giggled mischievously. "I'll take that as a yes." Once again, while looking me sultrily in the eye, she leaned forward, took hold of the hem of my gym shorts and slowly tugged them off, taking my panties with them.

Instinctively, I held my hand over my bush, embarrassed that anyone should see it.

"You don't have to hide from me, Tara. Your pussy is beautiful. Such a small, perfect little slit, and all your curly pubes soaking wet around it. Here." She sat back on her backside and slid her own panties off, revealing her own pussy to me for the first time.

It looked... different from mine. On hers, I could see the edges of her inner folds... her labia... sticking out of her slit, and I could see the distinct nub of her clitoris at the top. All that was hidden on mine. I don't know if that was the word, but it's what I thought at the time. She also had no hair down there except for a triangle patch of trimmed pubic hair pointing down to the top of her slit.

"It's different, isn't it?" she said opening up her folds with her fingers. "All women are. Just like all cocks are different. That's what makes this so fun. Like a buffet. You look around and find what you like. Your brother... fuck, he's got a great cock, and it's different than a lot of other guys. And your pussy is... beautiful." She slipped a finger inside me, the first time anyone had ever touched me so... intimately.

She let out a soft gasp and smiled. "No hymen?"

Trembling at these new sensations, I stammered, "T-tampons."

"Hmmmm... of course." She shifted her weight and crawled toward me. "Do you mind if I... give it a kiss?"

I held my breath as she lay down on her stomach, her head poised between my legs. Gently, she nudged my hand out of the way and inhaled deeply. "Hmmmmm... lovely," she said right before she placed her upper lips on my lower lips and kissed, blowing slightly into the folds, and causing me to lose my fucking mind. Never had I experienced this kind of pleasure. I threw my head back and moaned... loudly.

Realizing what I had done, I covered my mouth with my hand and tried to contain my voice. I couldn't, especially when she started tracing her tongue along my lips. I bit down on my hand to prevent me from screaming in pleasure just from that. Then... holy fucking god, she started eating me out in earnest. Her tongue explored every inch of my pussy, circled the entrance to my virginal tunnel, and flicked against my clit. It didn't take me long to achieve my first orgasm... ever. My first climax in my life, and it came from the ministrations of another woman.

My eyes rolled back in my head as I collapsed on my bed, pulling a pillow over my face to stifle the screams. Electric bolts originating from my core shot through my entire body, causing me to thrash and convulse, but still Shannon continued to lick. Eventually I came down from my climax and was able to breathe somewhat normally again.

"That... was fucking hot," I heard a male voice say quietly.

My eyes shot open, and I saw Steve standing at my door, grinning wildly and his hand down his shorts. From the motion at his crotch, I figured he was stroking his magnificent dick under his clothes. God, where hadthatthought come from?

"Steve!" I gasped as I looked for something to cover myself with. I could only find the pillow I screamed into and stuffed it between my legs, earning a playful giggle from Shannon. "What are you doing in here?"

"I just came to give my fiancée a goodnight kiss," he replied, still grinning. "Imagine my surprise when I find her eating out my little sister!"

I almost broke down in tears from the humiliation. What was I doing? Making out with his fiancée? Groping her body? Letting her... oh god... "I'm s-sorry! I don't... I didn't..." I covered my face with my hands, mortified.

Steve just laughed, the jerk. How could he laugh at me at a time like this? "Hey, relax, sis. Think is the first time I've watched Shannon with another girl? I've walked in on her like this several times."

I dropped my hands, not able to believe what I just heard. My eyes shot from Steve to Shannon and back to Steve.

Shannon, my womanly fluids shiny on her face, smiled and nodded. "It's true. I like both men and women... and... at the same time whenever possible."

"It's cool, Tara," Steve added, still stroking himself under his shorts. "I get it. I saw how you were looking at her... and at us before. It's understandable you wanted to try it for yourself. She's amazing, isn't she? Really made you cum."

Speechless, I just watched him fondle himself, the fabric of his shorts bulging under his hand as I tried to make out the shape of his cock.

"Take it out, honey," Shannon said. "I think she wants to see how beautiful your dick is."

Smiling and looking right at me, Steve removed his hand and slid his shorts down. As he did so, the band of his shorts pulled his cock down, and it sprang up when it was freed.

I gulped at the sheer size and shape of it. I didn't know it would be all... veiny and rigid. The head was bulbous and purple, with a single slit at the tip. And his balls... God, they were so big and weighty as they hung in their sack between his legs. Never in my life did I ever expect a man to look like this. Never in my life did I expect that my first sight of a man's penis... would be mybrother's. And it wasbeautiful.
