Susan just stood there a bit bothered with her friends tears. She looked down saw her very misshapen abdomen and then noticed two large lumps on both sides of her stomach. Then it dawned on her, "oh Jen that looks painful let me help." Susan stepped up to Jen and put her hands on her abdomen and gently stroked. Jen was surprised by her friend and the very new sensations she felt. One hand slowly slid down to the fleshy sheath that hid Jen's new cock and began to play with it. Jen began to feel very warm from Susan's touch and began to feel something shift in her abdomen. Susan kept at it as she was eager to see Jen's new addition and she felt the growing heat in Jen as she worked her hands gently. A twitch here and there which Susan felt was a sure sign the cock was on the move.
Jen let out a moan as she felt her large clit move gradually. As it did she felt her stomach flatten as her clit moved. Both Jen and Susan were fixated on what was going on and stared at her abdomen and crotch. Susan's hands were busy caressing Jen's crotch and midriff, while a bulge started to appear in the fleshy sheath. Susan grabbed that bulge and started stroking and Jen purred from the growing pleasure. The bulge just kept growing and eventually, the pink monster reared its ugly head. It was large, flat, and flared and continued to slither out.
Susan was shocked at the sight as Jen's new horse cock continued to swell. It was about 10" long and still half of it appeared to be inside Jen! As they watched Jen's abdomen flattened out and noticed her balls started to move. Susan couldn't take it any longer and she got on her knees and wrapped both hands around Jen's cock. Jen was overcome with pleasure and gave up fighting her body. Her rod continued to slide out and far from erect. She felt her swollen ovaries twitch with need.
Susan pumped the growing horse cock and was enthralled with its size as the last of it exposed itself. It was almost 30" long and 3" thick and just starting to get hard. As she played with it, licking the head, up and down the shaft, and stroking it the best she could she noticed there was a bunch of flesh bunched up at the base. As Jen moaned louder and squeaked from time to time, Susan looked up and noticed that the orbs in her abdomen seemed to be gradually lowering. She quickly became fixated on the sight and slowed her stroking as she watched. Jen's cock was hard and her balls were edging closer to her cock as her need to fuck grew. Susan kept on stroking as she lowered herself to get a better view of Jen's balls. The cock was twitching and throbbing as she worked it with her hands and tongue. Susan looked back and could see the bunch of flesh start to conform to a rounded shape as she noticed Jen's balls were almost free. Jen was moaning mindlessly as she overcome with the urge to fuck.
Susan kept watching Jen's balls squeeze through their openings gradually filling her sack. She was amazed just like her cock they were equally big, at least the size of softballs. Then suddenly with a subtle moist pop they dropped and shot into Jen's sack as she screamed from the sudden pain as they were pulled taught and recoiled from the fall. Once free Susan was shocked with the sudden ferocity of jen's sudden humping. Susan held on as she felt cock thrust into them, and watched her heavy balls swing back and forth.
Jen screamed out as her horse cock blew its load onto the bathroom floor. Jen was calmer now, but her cock was still erect and Susan was dripping wet from her own juices.
