...stumbles to her knees, and takes hold of Sarah's tail after coming down.
"Sis, what are you-" Before Sarah could continue, Suzy put her mouth around the tail breast's slightly elongated nipple "S-Suzy! Don- Please-"
Suzy pulled as much of the soft tissue into her mouth as she could "N-no! Please! Y-" Sarah struggled to try and get out of the position she was in, but it was no use, a combination of her tail being lodged into the chair, being in front of a desk, and pure erotic pleasure prevented her from moving.
By this time Sarah had given up on trying to escape her situation and began to accept it, stroking her breast cock in one hand and squeezing one of her regular chest breasts in the other "Ahh-hh, yeah-h." A bit of milk drooled out of the nipple on the end of her dick.
Suzy's tongue pushed forwards to circle around Sarah's tail, but upon contact with her skin, Suzy recoiled with an intense wave of pleasure "Mmmph!" Pop! Suzy's mouth lost its suction on Sarah's tail as she pulled back, the tail jiggled about just in front of her after the abrupt disconnection.
"Please, don't start this withou-hhh- finishing." Sarah pleaded to her sister, breathing heavily. Sarah, with both hands on her cock now, pushed her back parallel to the seat, in an attempt to push the tail back into her sister's mouth. The nipple brushed just to the side against Suzy's lower lip, bending a bit to the left.
Sarah shook a bit as Suzy's warm breath teased her very erect nipple. Suzy's hypersensitive tongue slowly and carefully brought it self ever closer to the nipple. Holding the tail boob in place with her two hands, she began to lick it as gently as possible.
The small amount of stimulation this caused got Suzy shaking. The breast, held in place by Suzy's hands, began to jiggle about, brushing against Suzy's many tongue nipples and causing her to shake even more. Suzy tried to stop shaking by pushing her mouth forwards and sucking on something, such as the large breast in front of her.
With that, a torrent of milk spewed from the two twin's many breasts. It only took that extra bit of stimulation to set them both off. Milk splattered and coated the bottom of Suzy's desk gushing from Sarah's boobdick, it shot down from her booblobes and shot forwards from her immense rack. Suzy's mouth was filled completely with milk, it made her cheeks bulge and dribbled out between her lips. By the end of the dual orgasm, half of the room was completely covered in milk and there was at least two and a half inches of fluid coating the floor.
With milk leaking out from under the door, someone would be sure to notice. Unless if perhaps reality shift applies here?
