Yes it’s happening

Marbef shows Jant some boulders that had a thick blanket of moss growing on them. She drops the few clothes she has and climbs onto the rock. Her vulva seems to be at the adequate height. “Should this be ok?” She asked spreading her legs.

Jant smiles more than pleased. “Yes this is fine. She moves in between her spread legs and begins to spread her mound with her hands. A waft of stagnant water came from her hole, it wasn’t a great smell but Jant could have cared less.

She began to tease the outer lips. Poor Marbef was dry as a bone inside. Outside was a thin layer of slime on her skin so Jant tried to coat her hand in It before taking one finger and attempt to tease it into her partner.

Marbef began to twitch and gasp at Jant ministrations. The centaurs fingers were soft and dexterous, teasing little moans from her lips and a warm fire alit inside her stomach. Marbef yelped as Jant slipped three finger in and began to quickly move them in and out the pleasure was becoming to much and the frog girl came giving a loud moan on pleasure as her body stiffened and convulsed.

“By the great one, that was quite a show. Thank you.”

Jant carefully mounted the rock with her front legs. Her rock hard cock bouncing under her. “I’m glad it was good for you.” She said. “Now that your body is ready I’m gonna need you to guide me in. It’s not like I can do it with it jumping like this.” They both chuckled and Marbef grabbed the dick.

Her hands were slimy like the rest of her body. The coolness felt great in contrast to the painful heat emanating from the rod. The frog girl began to stroke the cock, palming and caressing it. She took more time than was needed but Jant didn’t complain. She began to play with her breasts as soft moans escaped her lips.

After some play Marbef pressed the flared tip of the horse cock to her vulva. The sensation Jant could feel was indescribable.

Marbef placed a hand on Jant’s horse stomach causing the larger girl to flinch.

“Please be gentle and go slowly. I can be some what malleable, but I’m not that deep.”

“With how you were touching me I thought I was going to burst. If it feels that good inside you I might not be able to hold back.” Jant said pushing her dick forward. The flared tip pushed against Marbef but not enough to penetrate. Jant knew just from this that the fit was going to be tight. She readjusted herself so that she can get a little more control of the thrust.

Then Jant thrust forward and her dick was met with resistance and with an audible pop she was in. Marbef let out a guttural moan as Jant entered her so violently. Jant was groaning along with her, using all her willpower not to cum just from that.

Marbef’s insides were hot, wet, and most importantly tight as all hell. Jant could feel every twitch, every fold of her lovely pussy. She gasped and panted trying to endure. Marbef did the same watching as the mighty rod only went a quarter of it length before hitting the entrance to her womb.

Jant Knew she had bottomed Marbef on her cock. The flared tip kissing her cervix. Jant loved that feeling and ground her cock there as if it was an intense make out session where tongues would try to invade the other’s throat. (Marbef would undoubtedly be capable to do that.)

“Hoo, I’m full.” Marbef moaned massaging the cock as it gyrated against her womb. “It’s both pleasurable and a little painful. But I won’t complain.” She leaned forward and even Carrie’s the giant horse balls that were filled to the brim with cum, ready to impregnate her.

Soon Jant had to stop grinding, she wanted to knock. Her cock squelched on the way out it’s glory glistening with Marbef’s juices. Marbef could only admire the sight for a moment before it slid back into her bouncing against her cervix.

“My god you are so tight, and your caresses are so nice. I might not last much longer.” Sweat was beading on her sling as she gasped and panted trying to give her small partner as much pleasure as she could. Her balls were righted painfully as she resisted the urge to cum with sheer will power.

"Don't try to hold it. I'm ready, you're ready, let it happen." Marbef said caressing the under parts of the centaur. She hopes that batch of eggs will get strenght and vigor.

Upon hearing that Jant pressed a hand against her mouth to stifle the scream. Her other hand squeezed her breast hard. She g

Could feel her ball jump as the pushed her sperm through her cock and flood Marbef’s womb. The tip of her cock threatening to enter as it was pressed against it.

Marbef let out a surprised croak at these actions not ready for the amount of cum that can be released from a centaur. She came as the cum poured into her. She felt her womb fill immediately followed by the sensation of having over eaten as her stomach began to expand to a point. At that point she felt warmth at the entrance to her vagina as the cum began to leak around the cock.

They both gasp as they came down from the high. It felt like hours had passed before They could move. When Jant pulled her nos soft Cock from Marbef It came out with a pop and a flood of cum. They both watched as Marbef’s stomach deflated.

Marbef placed her hand over her hole to stop the cum. She asked Jant for her loincloth and then made sure none of the cum could escape. Once she was satisfied she looked up at Jant. “You held up your end of the bargain. Now I will hold up mine.”

Jant stopped her as she seemed to want to start the lesson’s now. “That can wait until we are back at your hut.” She sidled up to the rock motioning for Marbef to ride her. “Get on. Your in no condition to walk.”

Marbef thanked her and pulled herself onto her back. She wrapped her arms around Jant’s human torso. Where their skin touched they could feel each other’s cool sweat/slime and warm bodies. This sent shivers through them. Like this they went back to the hut. Looking like two lovers ready for a night time stroll.
