Jenny decided to help.
"Alright, I'll assume your straight and want to get into a girls panties, may as well become them. Try for a top."
"Hey, I'm 100% straight"
"You thought of a six foot tall cock, sure you are sport."
After muttering obscenities, he thought of a sports bra, what he thought they looked like. His body flowed into a small blue top.
Jenny's DD cup tits would never fit the top, even her original breasts would have a tight fit. "Try a larger size, like this"
She forced him to change to a reasonable size. Her suit flew off and she put on the top. Her breasts were smashed up into her chin since Tom had wanted a tight sexy top but he didn't know about women's bodies. Jenny made mirrors appear, with Tom appreciated since he could somehow see what was happening
"Oh fine, I'll have to fix this if I don't want to hit my chest everything I swallow." The top loosened enough until Jenny's chest was back out in front on display. "While were on alterations, you should loosen up or else you'll rip." She willed her breasts up two cup sizes and heard a ripping noise as her nipples burst out of the top. Tom wasn't in pain but was mad since the contact made him horny - he wasn't' sure if an erection was possible in this form. "You need to be stretchy if you want to survive this beach." He reformed on her DD chest and this time her breasts were cupped wonderfully as she expanded larger. She had breasts the size of beach balls but the same blue sports bra hugged her for dear life. Tom swore her nipples were a foot long as he felt their bulk. Jenny made sure her foot long nipples were felt to tease him. She returned to DD size.
"Ok, try for the bottoms. You can still be a top and a bottom if you have enough mass." Her chest was forced downward as a small amount of fabric lunged for her bare crotch. The swatch separated from the top, and her boobs went flying back upward. Jenny felt the fabric creep around her and then felt the front and back areas support her waist.
"Not too bad, but unless your trying to finger me your way too tight down there." The both stared at the huge camel toe in the mirrors. Tom let up and the suit looked normal. Jenny jumped and stretched and loved the felling of Tom all over her.
Tom decided the basics were covered, so he thought of a big 10 inch cock but on the inside of the front of the suit. "What is the pressure on my crotch.... What the hell you pervert.... oh that's nice" Jenny was cut off by the rhythmic motion of the disembodied lycra cock entering her. In the mirror only the hot babe thrusting was visible. He almost formed a second one in the rear until Jenny stopped him. "You had your fun, stop it or I'll make a jock strap, permanently."
A face appeared in the middle of her crotch, Tom spoke and each time his mouth opened her pussy was exposed. "Ok, Ok. You didn't mention how much fun this is! By the by it's getting like a swamp down here!"
Jenny was naturally aroused and getting wet but figured a little torture was in order. Her pussy overflowed with juices soaking the bottoms so bad she left a puddle beneath her! "Sick, I'm not your personal toilet." "It's not pee, you'll have to get used to absorbing liquids." "Damn it, fine." Her crotch was bone dry as she 'creamed' her pants, every girl will want one now! "Quit it already and let's try some thing different...ack ack.." Jenny wanted to shut him up so she grew a foot long penis out her slit. It looked like Tom was sticking at his tounge at her. "Your not much fun for such a kinky garment."
Tom decided to show her - the garments turned into black leather chastity belt and matching bra with metal studs and all. Jenny was impressed, even with the dildo plug in her rear and massive dildo in her slit. "Wanna try some thing completely different?"
