"A tit-fuck would be fine"

"How will I retrieve the sample?" Miss Williams asked.

"Same way as you did before, I guess," responded Ben.

Miss Williams sighed, and removed her lab coat, bundling it up and dropping it on the floor for a pillow. The blonde scientist was now wearing nothing but her, panties, stockings & garter belt. Her large breasts wobbled pleasingly and Ben's 11 inch monster throbbed with a life of its own.

Miss William reached into an equipment cupboard and pulled out a blanket, which she lay on the floor beside her white coat. With a sigh of resignation, she grabbed a test tube and lay down on the floor. She still looked rather hard-nosed, but gradually seemed to be thawing somewhat.

Ben squatted over the gorgeous scientist, his monster dick resting between her huge titties. She grabbed her breasts and rolled them up and down Ben's cock. Ben put his arms behind his head as he enjoyed the blissful sensation of her soft sensual flesh squeezing and massaging his unwieldy cock. Up and down his shaft, the fleshy mounds worked their magic. Looking up at the large wall mirror, he thought of all of the women who might be watching him and he imagined them getting as excited as he was. He smiled and blew them all a kiss. Then Ben felt his balls contract and his shaft fill once more with hot fiery liquid.

Ben gasped as his cock hurled his goo across the pretty blonde scientists upper body. There was so much of it this time that it splattered into her chin and smeared up round her face and dribbled down her neck.

Ever the professional, Miss Williams continued to milk the last dregs of Ben's cock with one hand and one soft breast, whilst she scraped up the fast escaping sperm with the test tube in her other hand.

When Ben's cock would yield no more, she indicated that he should get up whilst she finished cleaning up.

"Now then, Ben," Miss Williams commented matter-of-factly, "for your seventh load - I assume that you can manage a seventh load - I want run a slightly different sort of test."
