Mea culpa

I remember it was raining that October afternoon, the gloominess of the day foreshadowing winter. Sitting on the couch by the fireplace, I looked for at least the tenth time at the Polaroid photos I held in my hand.

One of the young women in the photos was someone I’d never seen before, but the woman kneeling between the stranger’s legs was all too familiar to me. It was my twenty-two-year-old stepdaughter Cassandra, home for a weekend from university. Though Cassie had her face buried in the other woman’s exposed pussy in most photos, there was no doubt about her identity. Or what she was doing.

As shocked as I was by the photos I’d found hidden in my stepdaughter’s old drawer, I simultaneously felt a strange yet not unpleasant sensation deep in my gut as I stared at them.

Sighing, I leaned my head back against the couch and closed my eyes. It wasn’t as if Cassie didn’t date men, I thought. The phone we’d bought her years ago rang constantly when she was home. Usually when I answered it for her, it was some excited guy on the other end asking for her. Of course other women called too, but Cassie had so many friends I never gave it much thought.

I opened my eyes and looked at the photos again. The woman receiving cunnilingus from my stepdaughter was strikingly beautiful. With short blonde hair and a cute face, she sat on the edge of a chair with her skirt pulled up to her waist, legs spread wide. A smile played on her lips as if she thoroughly enjoyed what Cassie was doing to her. She’d entwined the fingers of one hand in my stepdaughter’s brown hair as if encouraging her.

I idly wondered who’d taken the photos while unconsciously undoing the front of my jeans. Barely aware of what I was doing, I stared at the revealing pictures while letting my free hand slip under the elastic waistband of my panties. My fingers curled through my pubic hair to the hollow of my sex and began gently rubbing the swollen lips of my pussy.

My breathing quickened when the tip of my index finger brushed my clit, and suddenly I was masturbating in earnest. So absorbed was I in the sensations from my fingers that I didn’t even hear the front door open when my stepdaughter came home. Only when she laughed aloud did I notice her presence.

“Stepmom? In the middle of the day?”

I quickly pulled my hand from my panties and sat upright on the couch, nervously trying to button my jeans. My eyes nearly bulged as I stared at the blonde woman now taking off her coat by the door.

“Cassandra,” I said weakly, “what are you doing home? I thought you were with friends!” I glanced at the wall clock. “It’s only twelve-thirty… why are you back so early?”

“Relax, stepmom,” she said, laughter still in her voice. “Our plans fell through because of the rain.”

As she walked toward me, she saw the photos I still held. I literally watched her pale, the laughter disappearing.

“Oh wow… how did you find those? I thought I hid them well.” She sat beside me on the couch and snatched the photos from my hand. Then understanding flashed in her eyes. “Oh wow… they turned you on, didn’t they? These pics of me and Barb got you horny. That’s why you were doing the old ‘quick finger mambo’ here, right?”

I knew I couldn’t lie my way out of this. Everything my stepdaughter said was true.

“Yes,” I admitted, feeling myself blush. “I guess they did excite me, sweetheart. But Cassie… are you… I mean… do you…”

“Am I a lesbo?” she finished my question. “No, I’m just bisexual, I guess. I like guys too, but I enjoy variety. Barbara and I hook up sometimes for these kinds of fun, like in the photos. Hey! That reminds me! Why were you rummaging through my old stuff anyway?”

“I wasn’t rummaging, sweetie!” I protested. “I was looking for items to donate to Goodwill. I just happened to find those photos.”

I suddenly noticed Cassie looking at my lap. When I glanced down, I saw I hadn’t properly buttoned my jeans. They gaped open enough to reveal my panties, the shadow of my dark pubic triangle clearly visible. Yet I made no move to close them.

“That woman in the photos,” I heard myself say. “Barbara? She’s… she’s very beautiful.” As the words left my mouth, I couldn’t stop my eyes from dropping to the front of my stepdaughter’s sweater. I saw the small bumps of her nipples and realized she wasn’t wearing a bra.

“She is very beautiful,” I repeated, a shiver running down my spine as I reluctantly looked back up.

“Yeah,” Cassie said softly, now staring intently at me. “She is.”

She scooted closer on the couch and casually placed her hand on my denim-clad knee. “I could call her if you want. She lives just a few streets over. Want me to invite her?”

My heart pounded in my chest and I could barely speak. “It’s still raining outside. She’d get soaked. Besides, I… I…”

Whatever I’d meant to say died when Cassie suddenly leaned in and kissed me. She caught me so off guard I didn’t resist. Instead I returned the kiss passionately, parting my lips to let her tongue slide into my mouth.

I made a kittenish squeal when her hand moved from my knee into my open jeans, fingers gently rubbing the sensitive, swollen lips of my pussy through the thin fabric of my panties.

Then, with a skill that amazed me, Cassie twisted her hand into the crotch of my panties and sank a finger deep into my cunt. I heard myself moan with pleasure as my stepdaughter fingered me while I sucked desperately on her tongue…
