I pull his pants and underwear down, and his big black cock springs up and slaps me, already erect. The size would be shocking if I hadn't already seen it before, it's nearly the size of my forearm. I think about putting it in my mouth, but I have to remind myself I'm not here to give Bossman a blowjob, I'm supposed to be demoing the lube. I take the bottle and slather the lube all over his dick. The silicone stuff is a lot slicker and silkier than water-based lube, but it still requires a lot of product to cover his whole penis. I use a lube applicator to shoot some lube into my ass before I turn around and let him take over.
Bossman leans over and whispers into my ear. "Solo play is great, but it's time that you experience everything that the world of sex has to offer." I feel Bossman's consideration towards me. He not only wants me to be a more well-rounded salesman, but also have a more fulfilling sex life as well. I couldn't ask for a better boss.
He bends his knees down enough that the tip of his cock can slip into my ass. He grabs me by my thighs and lifts me up, while straightening his knees as his stands back up again. My back is against his chest and my legs are spread up and open in a V shape holds me by my thighs. He eases me lower, causing my ass to slide down his shaft. I let out a moan of pleasure and surprise. Normally, if I fuck a dong as thick as him, I need to progressively work my way up using different sized toys, and even then, it takes a while to work it in slowly and carefully before I can fuck it. It's a testament to his skill at moving me down his cock, as well as the extremely high quality of the lube.
Bossman starts heaving me up and down on his cock, and I moan every time on the way down. I've had big dongs in my ass plenty of times, but the sensation of having sex with a real man is much more than just being penetrated. I feel his chest and abs on my back, his arms and hands holding me up. I feel my little dicklette flopping around as I slide up and down the shaft. The sounds of his breath, the smell of his cologne, the feeling of connectedness to another human, it all elevates the experience so far beyond dildoing myself while watching porn.
"Any pain Riley?" he asks.
"No Boss, everything's silky smooth, keep going!" I glance over to the customer, she looks impressed.
"This stuff can really facilitate deep penetration, huh? How about fast thrusting though, will it still last with that kind of friction?" she asks.
By now a crowd is starting to form around the demonstration area. Bossman puts me down, and I kneel on a highchair facing the seat back, so that I'm at the appropriate height for him while he's standing. I bend over a bit and guide his cock into me. He holds me by the hips and thrusts into me balls deep. He starts pumping, gradually increasing in speed. Eventually he's at jackhammer level, going nearly full strokes 3 or 4 times per second. I'm pretty sure I'm screaming at this point, but the sound is drowned out by the cheers from the audience and the loud smacking of his thighs onto my ass. I see a few men in the audience with tents in their pants, and women with their hands down their skirts.
Since this is an endurance test of the lube, we keep going for 20 minutes. By the time Bossman fills me with cream, I've already came all over the chair several times. Normally, the less expensive water-based lubes sell better than the silicone-based ones, but right now $50 bottles of Silky Sex are flying off the shelves. Several of my co-workers come to me, to congratulate me for losing my virginity as well as for driving sales so well. What an amazing day, working the best job in the world at Bossman's Sex Emporium.
