A couple of months ago, my cousin sister moved in with me. She needed a place to stay while she attended college nearby, and I was more than happy to help. She was always playful and comfortable around me, but recently, her behavior had become increasingly flirty and bold.

It started with small things — she’d change clothes in front of me, often wearing just her bra and panties. Her comments became more suggestive, and she’d touch me casually, her hand lingering on my arm or back longer than necessary. I noticed how her piercing blue eyes would follow me around the room, filled with a mixture of curiosity and something more.

Being just 18, I was new to these sensual feelings, and every touch and glance made my heart race. One evening, she offered to give me a massage. I had been feeling tense, so I eagerly accepted. Stripping down to my bra and underwear, I lay on my bed, waiting for her to start. Her hands were warm and skillful, working out the knots in my shoulders and back. I relaxed into her touch, my body melting under her fingers.

Her hands moved lower, massaging my lower back and then my buttocks. I tensed for a moment, unsure of her intentions, but the sensation was so good that I couldn’t bring myself to stop her. Her fingers slipped under the waistband of my panties, brushing against my skin. My breath hitched, and I felt a wave of excitement and fear wash over me.

She leaned closer, her breath warm against my ear. “Relax,” she whispered, her voice soft and soothing. Her fingers dipped into my panties, finding my clit. She began to rub it gently, her other hand massaging my back. I was shocked, but the pleasure was immense. I started moaning softly, my body responding to her touch in ways I hadn’t imagined.

Her fingers moved expertly, slipping in and out of me. My moans grew louder, and I felt a wave of pleasure building up inside me. She continued, her movements steady and sure, until I couldn’t hold back any longer. I came hard, my body shuddering with the intensity of it.

As I lay there, catching my breath, she leaned in and whispered, “Next week, I’m eating you out.”

The following week, her teasing became more intense. She would walk around the house in skimpy clothes, her body tantalizingly close. One night, she crawled into bed with me, her hands roaming over my body. She pulled down my bra, exposing my small, fresh boobs. Her mouth found my nipples, sucking and licking them until they were hard and sensitive.

Her hand moved down to my pussy, slipping under my panties. She rubbed my clit, her fingers slick with my wetness. I moaned, my body arching into her touch. She kissed her way down my body, her mouth hot against my skin.

When she reached my pussy, she licked me slowly, her tongue exploring every fold and crevice. The sensation was overwhelming, and I couldn’t help but moan loudly. She teased me, her tongue flicking over my clit before plunging deep inside me. I was on the edge, my body trembling with need.

She brought me to the brink again and again, her mouth and fingers working in perfect harmony. Finally, she sucked hard on my clit, and I came, my body shaking with the force of my orgasm. She didn’t stop, her mouth and fingers continuing their relentless assault until I came again, even harder than before.

As I lay there, completely spent, she crawled up beside me, her fingers still gently stroking my pussy. “I told you I’d make you feel good,” she whispered, her voice filled with satisfaction.

It was the best feeling ever, and I’m still wet thinking about it. The thought of what’s to come has me on edge with anticipation.
