Jeff feeling his new large cock straining against Jen's latex form, made his way downstairs. He wanted nothing more then to now blow a load into his mother.
Once Jeff reached the bottom of the stairs, he saw his mother Gabriel still being fucked by his father Helen. His sister Amber he now realize seems to have tired out and went into the kitchen to grab some food. Jeff approached his parents with his hard three foot cock pulsing within Jen's latex confines.
Jeff was now in front of his mom when he felt Jen change him again. His cock split into two but stayed the same length and girth. He now felt two, three foot, soda can thick cocks straining against Jen's latex form. Jeff saw his mother body get changed in response to his new growth. He saw her tits enlarge till they where resting on her knees, covering most of her torso. He then saw his sister's change into a black latex suit that covered most of his mother's body, only leaving her head exposed. The last thing his sister's changed on his mother was her nipples, they changed them into pussies.
Jeff knew what to do immediately and thrusted his cocks into each of his mother's tits. Jeff felt his dick easily enter his mother's nipple-pussies, getting swallowed in her pillowy mounds. His mother's tits bounced sexily at each of Jeff's thrusts. Jeff camed three times in the span of a minute. After his fifth orgasm, he felt the insides of his mother's tits change. He felt the insides of his mother clamp down and start to milk his cock for all his cum.
