Jill reached down and stroked his long hard member, while shoving one of her sensitive teats into Josh's mouth.
Josh instinctively began to suck on it as he slips a hand into Jill's wet vagina. Slowly rubbing against her clit.
Marcus watched wordlessly for a moment, his prepubescent body not responding like his teenage mind. Almost absently he tosses the dice onto the board. 5 and a 6, his piece moving forward Marcus picks up a card.
"Like to watch but unable to join. Fix this we shall and feel both of their pleasure"
Marcus didn't quite understand the card but before long the game showed him. Marcus shot up to six foot in height. Smiling at himself He could feel his loins stiffening in response to his friend's coupling. Finally he thought to himself he was getting tired of being a child. But the changes did not stop there. Marcus started itching his chest as his nipples began to tingle. Looking down he stared wide eyed as his chest slowly expanded into two sets of large perky breasts.
When they stopped at around a D size a bolt of pleasure shot through his body. His right tit felt as if it where being sucked and as he looked back to Jill and Josh he realized that he was feeling their pleasure. A fact which became more apparent when he began to feel Jill stroking Josh's penis with ever increasing urgency.
Moaning Marcus threw his head back heedless of his shrinking waste, widening hips or growing hair. For a few moments he was basking in their pleasure to notice that they intended to turn it up a notch. Without warning Marcus shot bolt up right, he could feel himself being penetrated. Looking down at his crotch Marcus saw a beautiful pair of vaginal lips below his aching penis where his balls should have been, being stretched by an invisible rod.
"Yes, Yes!" He screamed as he could feel both sides of the sex. Jill's vagina being stretched and penetrated and Josh's penis as it was stroked and sucked by her vaginal muscles. It was glorious and it wasn't long before the three of them orgasm together. Josh spilling himself inside of Jill, Jill screaming at the top of her lungs and Marcus spewing his seed across the room while joining Jill's call.
