You give in.

“Ugh, okay fine I’ll try it.” You aren’t sure, but riding on Tharen, looking so sexy, cocks dueling in your ass, is just magical. You just need to know.

Borum slips out, “Sweet, be right back.” You can’t resist sucking on Tharen’s amazing breasts as he bounces you up and down on him. “I’m back. Just gotta get back inside. Ooh, no, I wanna be in your mouth when you change.”

“Is that safe?” You ask.

“Hell ya, we do it all the time. The magic accommodates. Heck, having others inside of you, or on your cock when you shift can even give them a bit of influence on how you look.” He hands you a thin shimmering gold chain belt. “Here, put it on while we are fucking you and we can help you look sexy as hell.”

The thought makes you nervous. You stand up and take a step back, “What if I don’t want you to have any control?”

Tharen sits up, “Then don’t. We don’t mind. It isn’t so much, control, more like, influence. Say for example you concentrate on becoming a sexy blonde and I think, I hope she has big breasts, if you aren’t clearly envisioning your breast size, my influence will make them larger. I just really love the feeling of having the person I am fucking change form around my cock. Watch.” He crawls over, slurps your cock into his mouth, then as he sucks it in to the base, he turns into a 5’ 1” woman with a mop of short red hair. You cum instantly as his shifting throat milks your cock. He stands up, twirls around, and wipes the corner of his sexy mouth. “See, my tits are much smaller, short hair, perky ass. You influenced me. Pretty sexy too.” He shifts back to his male self. “But if you don’t want to, by all means, put it on now while we are just watching.”
