Ben ran into the living room and peeked out through the curtains. A slim girl in slacks, and a translucent blouse covering a bikini was standing on the front porch. "Oh shit" he hissed to his mates. "It's my old girlfriend Samantha. She must be back from overseas...Uh..you hide out back and I'll get rid of her."
The oiled up, semi-naked hunks withdrew to Ben's bedroom, while Ben threw on a baggy tee shirt, board shorts and baseball cap. He pulled open the door.
"Bennnnie..!" squealed Samantha, an excitable 19 year-old blonde, and threw herself against the now girl-averse hunk. On tippy-toes she pressed her lips against his and grabbed his shoulders. "Oh you've been working out!" and pecked at him again, harder.
Ben wasn't sure what to make of this as he no longer had the slightest interest in girls...until he noticed that Samantha was no longer on her toes. In fact she was looking eye to eye with him! Ben pulled his head away.
Samantha's rapid increase in height was accompanied by a broadening of the shoulders that left the blouse pasted across a broad chest, and the bikini top snapped apart. The girlish arms had been replaced by strong forearms that now cupped Ben's shoulders.
Ben whistled. "Dammmmn.. I guess you're Sam now", reaching down to cup the nice new basket in Sam's speedo briefs. Sam smiled widely, opening his mouth to display a silver tongue-stud. The tongue slid down over the broad chin, graced by a fine blonde chin-beard, and waggled its way to Ben's mouth.
"I guess I have no more objections to sucking your cock now" Sam said. He knelt down and grasped Ben's engorged cock between his teeth, sniffing the crotch through the lycra. "Are you hiding some other playmates - " he pulled the cock free and teased it with the tongue-ring - "Benny?"
Ben's eyes fluttered orgasmically as he tried to take-in all the erotic stimulation, and the sudden bizarre changes he had witnessed. "S-S-Sam, w-who's in the car outside?" he asked, gesturing with one hand through the still open doorway.
