Mr. Mendes or "Frankie" was still sucking on her breast, but with every passing second he was growing larger, ...older. Only a few more seconds had passed and he was out-growing rosie's lap. Almost by instinct "Frankie" streached his lengthening legs out to the ground, supporting himself- but Rosie was practically oblivious to the changes happening to her "Frankie". He was now looking to be in his 10 year, and still growing! His body getting taller and older, his head still bent over in her breast. Then "Frankie" hit puberty. His body began to grow taller and taller, hair sprouting from his groin and armpits. Testosterone began to flow though his body, Slowly turning him into a man. His face grew older, more handsome and angular. Mr. Mendes was obviously bigger than rosie now, and obviously aroused by his situation. Meanwhile Rosie was calm, thinking nothing out of the ordinary was going on. Mr. Mendes now looking to be about 16 years old. Hair began to grow over his face, then sprouting from his chest and stomach. Still sucking on her breast, mendes was maturing. A thin beard now covered his handsome face. He could easily pass for a 18 year old now, or older. His thin body then began to gain size and mass. As Mendes sucked, his body grew thicker and more muscular, turning into a full sized man, with his head still submerged in Rosie's chest. Now he had turned into a young man of about 20, and he was obviously aroused. Rosie began to take notice of what was actually happening....
