20F I let the delivery guy fuck me on the kitchen counter while my flatmates were home

It was a Friday night around 11 pm and my two flatmates were in the living room binge watching some series with the volume up loud. I ordered pizza because we were all too lazy to cook. When the doorbell rang I answered in just my tiny sleep shorts and a cropped tank top, no bra, nipples already hard from the AC. The delivery guy was cute, early 20s, tattoos peeking out from his sleeves, and he definitely noticed how little I was wearing. I signed the receipt slow on purpose, leaning forward so my tits pushed against the fabric. He handed me the box and our fingers brushed longer than necessary. I asked if he wanted a tip in cash or something else. His eyes flicked to the living room then back to me. I stepped aside, let him in, and closed the door quietly. Without a word he set the pizza on the counter, grabbed my waist, and lifted me up so I was sitting on the edge. My shorts rode up instantly. He yanked them down with my thong in one pull, spread my thighs wide, and dropped to his knees right there on the tile. His tongue hit my clit fast and hungry, licking in long flat strokes then flicking quick while two fingers slid inside me curling hard. I was dripping within seconds, biting my lip to stay quiet because my flatmates were literally ten feet away laughing at the TV. He stood up, unzipped, pulled out his thick cock already leaking, and rubbed the head along my slit teasing before pushing in slow. I gasped but covered it with a fake cough. He fucked me deep and steady, one hand clamped over my mouth while the other gripped my hip pulling me onto him harder. The counter creaked softly under us but the TV drowned it out. I wrapped my legs around his back, heels digging into his ass urging him deeper. Every thrust made my tits bounce under the thin top. He pinched my nipple through the fabric, rolling it hard while he pounded faster. I came clenching around him so tight my whole body shook, nails scratching his arms. He groaned low into my neck, thrust a few more times then pulled out and came across my stomach in hot thick ropes while I watched it drip down my skin. He wiped himself on my shorts, zipped up, gave me a quick smirk, and slipped out the door like nothing happened. I pulled my clothes back into place, wiped the cum off with a paper towel, grabbed the pizza box still warm, and walked into the living room acting normal. My flatmates thanked me for the food without a clue I was still leaking his cum down my thigh the whole time we ate
