Jenny opened the door to the welcoming odour of two horny sluts. They weren't far off going into heat, although it was still a struggle for the horse herm to maintain her control. She quickly ushered the herm customer next to her and shut the sound proof door behind them.
Jizzmilk coated the floor and more splashed out of the tank as the two sluts rolled and played in it. The horse herms quickly disrobed and enjoyed a moment of making out together until their cocks were at full mast and then they charged with their battering rams.
Susan shrieked with shock as strong arms lifted her high into the air. Mrs Tinson gazed back at her in equal shock as their heads bumped into the ceiling. The wide, blunt tip of a spongy cock pressed between her legs and her shock turned into lust. Mrs Tinson's open mouth twisted into a maniacal grin, mirroring her own desire.
'Ooooohhhhh yeeessssssss!!!' screamed the sluts as they slid back towards the floor together. Inch after inch of horsey cock pierced their greedy cunts. When the medial ring pushed through their stretched lips they screamed even harder and milk sprayed from their tits.
Susan hooked her legs back around the legs of the herm fucking her and leant forward to resume making out with Mrs Tinson. The divorcee did the same and their tongues mashed together as milk continued to dribble from their teats onto the floor. Slowly the herms thrust their hips as much as the position would allow and together they all moaned.
The herms switched their grips from waists to wrists and leant back. Using the sluts arms like reigns, Jenny and the customer bounced Susan and Mrs Tinson like they were riding them through a field. They whinnied and brayed and the sluts screamed with delight.
Susan pulled herself toward her herm with every thrust until her legs started to shake. Newly developed muscles rippled and squeezed the cock inside her, milking it for its precious seed. She felt like she was on the edge of something great. Something more than just the earth shattering orgasms she'd become addicted to.
