Watching her Tak-kun and his girlfriend make out was too much for Haruko. Tak-kun was fucking the DD-Cups of Ninamori, and Ninamori was loving every moment of it. Ninamori's tits were bigger than Tak-kun's entire head, and he was still sucking away at the fat nipple, even though no milk was pouring out of it. Haruko decided to join in the fun.
As she had unbirthed Tak-kun, Haruko could now produce all the milk she wanted to. She could make her breasts swell to any size. But why not start small? Not that Haruko's breasts were small now...indeed, there were D-Cups now. Haruko made her breasts swell even more, to the F-Cup range. She smiled when she got off the couch. Haruko seemed to have no troble walking with her bigger tits. Tak-Kun was still tit fucking Ninamori with all his might, and Ninamori kept moaning in pleasure. Tak-kun's dick was in Ninamori's clevage, with his head buried in the tit flesh of Ninamori. He was still sucking, judging from the slurping noises. Haruko then touched Tak-kun in the back with her massive tits, sandwiching him against her and Ninamori's tits. Tak-kun kept fucking Ninamori's tits, but he was fondling Haruko's tits too.
Ninamori noticed that Haruko had decided to join in, and moved off of Naota just slightly. As she did, Naota screamed in pleasure as he sprayed his fuck juice all of Ninamori's tits. His very first orgasm. Ninamori moved off of Naota and started to lick the love juice off her gigantic tits. The love juice tasted sweet to the sex-crazed Earthling girl.
Naota looked dissapointed that Ninamori had backed off. He sat up on the floor and looked at Ninamori, pleading her to come back to him.
"It's her turn, Naota" said Ninamori, pointing behind Naota. Naota turned around and saw a wall of tit flesh! Haruko's nipples were dripping with milk, and Naota needed no coaxing. He put his mouth over the fat tit, which filled his mouth, and started to suck. Warm, refreshing milk flooded Naota's mouth. Not only did drinking Haruko's milk caused his hormones to skyrocket, but he gained more stamina as he drank. Naota put his dick in Haruko's clevage and started to fuck her tits.
