I never planned for it to happen. At forty-three, I figured my wild days were behind me, replaced by quiet evenings and the occasional glass of wine after work. My son had just turned twenty-two and was home from college for the summer, bringing his friend Derek along for a few weeks. Derek was twenty-one, tall and broad-shouldered from years of college baseball, with dark hair that fell into his eyes when he laughed. He called me Mrs. Ellis at first, polite and distant, but that changed fast once the three of us started sharing the house.
The heat that summer was relentless. We kept the windows open at night, fans humming, and I often wandered downstairs in nothing but a thin tank top and cotton shorts, thinking everyone was asleep. One night, though, Derek was already in the kitchen, leaning against the counter with a glass of water.

The light from the fridge caught the line of his jaw and the way his shirt clung to his chest. We talked quietly about nothing at first, his voice low so we wouldn't wake my son upstairs. Then the conversation shifted. He admitted he'd always thought I was attractive, had noticed the way my hips moved when I walked, the curve of my breasts under summer dresses. I should have laughed it off, but instead I felt heat pool low in my belly.
I stepped closer, testing the air between us. Derek didn't move away. His hand brushed my waist, tentative at first, then firmer when I didn't pull back. We kissed right there against the counter, slow and deep, his tongue sliding against mine while his fingers slipped under my tank top to cup my breast. My nipple hardened instantly under his palm. I could feel how hard he was already, pressing against my thigh through his shorts. We didn't speak much after that. I led him to the guest room at the end of the hall, the one farthest from my son's bedroom, and closed the door behind us.
Once inside, everything became urgent. Derek peeled my clothes off piece by piece, his mouth following the fabric. He sucked my nipples until I had to bite my lip to stay quiet, then dropped to his knees and spread my legs. His tongue was hot and insistent, licking long stripes through my folds before focusing on my clit. I gripped his hair and rocked against his face, coming hard and fast the first time, my thighs trembling around his head. He stood, wiped his mouth with the back of his hand, and stripped. His cock was thick and veined, already leaking at the tip. I wrapped my fingers around it, stroking slowly while I told him how good he felt, how wet he'd made me.
He bent me over the edge of the bed and pushed inside in one long thrust. The stretch burned in the best way. Derek fucked me with steady, deep strokes, one hand on my hip and the other reaching around to rub my clit again. I came a second time with my face pressed into the mattress, muffling my moans. We switched positions twice more: me riding him, grinding down until he groaned my name, then him on top again, pinning my wrists above my head while he drove into me harder. Sweat slicked our skin. Every thrust made wet sounds that filled the room. When he finally came, it was with a low, guttural sound, pulsing deep inside me as I clenched around him.
Afterward we lay tangled together, breathing hard. Derek kissed my shoulder and whispered that he'd wanted that for months. I told him it couldn't happen again, but we both knew that was a lie. Over the next two weeks it happened four more times, always late at night, always in that same guest room. Each time grew dirtier. He took me against the shower wall one morning while my son was out running. Another night he had me on all fours, pulling my hair gently while he thrust from behind and told me how tight I felt. I came harder than I had in years, again and again, until my legs shook.
By the time Derek left with my son for the drive back to campus, my body felt marked by him. I still think about those nights when I'm alone. The risk, the secrecy, the way his hands knew exactly where to touch me. It was never supposed to be more than a summer fling, but the memory stays vivid. Sometimes, when the house is quiet, I still slip into that guest room and remember how it felt to be wanted like that again.
