Mel stood, back to the door she'd just come through, smirking lustfully at Sophie and I, where we lay. I was naked, lying on top of Sophie, my softening dick buried in her ass as she ground back against me. My cock twitched as Mel began to walk forwards, looking as sexy as the first time I'd laid eyes on her. She was built like Sophie, with bulbous tits and a big, bouncy ass, but she was thinner, a truly hourglass figure as her waist narrowed from her slender torso, before her hips flared out. She had obviously gone out partying the night before, still wearing a scandalously tight strapless dress which reached only a few inches down beneath the curve of her ass, and surely no more than an inch above the pink flesh of her areolae. The dress was black, and made from a thin, sleek material which made it obvious that she had no bra on, as she reached up and cupped a breast in one hand, squeezing gently, and watching the look on my face.
"What do we have here?" She asked.
Sophie answered, "you remember our friend David, don't you? Well he came around last night to keep me company and ... you could say he came this morning, too."
Walking out of sight, behind me, Mel placed her fingers on my hips and gently pulled me back, Sophie following with her ass, unwilling to let me go, as I knelt, upright, her ass sticking up in the air before me.
Mel's fingers slid slowly up my body, giving me goosebumps, as she pressed her body against mine. My dick twitched again. Sophie began to grind back against me more enthusiastically, as I began to grow hard again, slowly.
I felt Mel's breath on my ear as she peered over my shoulder, "mmm, did you fuck her ass already? God, you look like such a slut, stretched around his cock, Soph. Now I know why you were in the bathroom for so long last night, I wouldn't have gone out if I had realised you were inviting dick over!"
Sophie tittered self-consciously as Mel wrapped one hand around my torso and the placed the other on Sophie's ass and she slowly pried us apart. Now Sophie groaned in protest as she felt me slide out of her, my dick shiny with my jizz.
Mel moaned ever so gently, as her lips caressed my neck, "looks like I got here just in time."
