being a couple’s third, laying on my stomach, him grinding on my ass, my tongue swirling around her gloriously swollen clit, weaving between her soft folds…he pushes inside of me, filling me slowly, his hands on my waist, her hands holding mine, him fucking me slow and deep, her hands in my hair, her toes curling as her feet rest on my back, my swollen head dripping relentlessly, grinding needily on the bedsheets, him massaging my prostate with every thrust, my hands sliding up her stomach, down her thighs, tracing along her nipple, around her breast, under her arm, pinching one nipple and skating a finger along her collarbone, wrapping a hand along her neck, sliding up to steady myself on her slender shoulder, moaning into her glossy lips as he thrusts deep and greedy to my core. my legs are shaking, i feel myself being pulled apart as i cling to her sweetness and throw my hips back into his desire.
