Chuck went and began typing things down for a while, Mandy was interested on what ideas he had... that is until he pressed enter. Mandy began to grow larger as they now reached 7 feet, even taller than Chuck! His balls swelled larger to fit his size as he moaned in his feminine voice. Mandy could feel his fucking hole swell and grow bigger, more plump, and softer as it looked like a massive puckered donut. Suddenly his lower parts began to tingle as more hair grew in and the Bush around his base grew thicker. The foreskin grew more on the tip becoming more rubbery and stretchy as he could feel smegma appearing inside as the musk on him grew stronger, they could also control it now. Suddenly he could feel even more testosterone flowing through him as he moaned causing his voice to deepen and more hair to sprout around the base.
The large cock turned to Chuck as the foreskin slowly pulled back revealing a smegma covered tip, the cock then lunged onto Chuck's dick and began giving a blowjob. After Chuck came Mandy brought his tip up to Chuck's face as a large glob of pre leaked from their mouth.
"Lick me clean." Mandy demanded
"W-what?" Chuck asked
"I want you to lick me clean, you gave me all this so I expect to be cleaned as I want." Mandy said in his deep voice
Chuck grabbed onto the foreskin and began licking the nasty tip and teasing the slit with his tongue, after swallowing he went behind Mandy and began to fuck the new plump hole with allama his might. After they both came they both fell onto the floor.
"Do you think the kids would mind having two dads?" Chuck said
"Probably, especially since I'm a cock." Mandy said
"So... what now?" Chuck asked as he rolled over and spooned his massive squishy cock husband.
