Liz runs. Fast.

Liz immediately jumps and runs back down the hall to her room, her newly swollen dick and breasts bouncing and bobbing the whole way. She burst into her room and slammed the door shut. The image of her brother lifting those weights was still fresh in her mind. Her flaccid 7 inch dick stiffened again, pointing straight out and growing to 9 inches. Without any hesitation, she groped her unit and stroked back and forth. Her other hand went to her breast almost magnetically. She massaged and pinched her huge nipples, and in no time at all shot huge streams of her cum across the room, smacking the wall. Liz moans as the tingling once again overcomes her. She manages to open one eye to observe the wall across from her. "Wow...that's more cum than I've gotten yet..." Her moaning grows louder as she feels her penis lengthen and thicken further. Her nipples follow suit, growing in length and width. Her boobs also bubble, becoming larger, perkier. When the orgasmic, tingling growth subsided, she looked down at herself. Her breasts doubled in size, a very round a full H cup with nipples at least 2 inches long, 1 inch across. She parted her giant breasts to get a look at her new cock. She gasps at what she finds. Her previously 9 inch hard on went soft again, but was easily a foot long. Liz became aroused at seeing this and got hard once again. She watched it stiffen and grow to its full length of 18 inches. Her boobs bounced back together as she let them go. She was able to see the head of her dick ahead of her tits.
