Swift moved over to the couch and took a seat. "If this stallion is pestering you to be his marefriend. The answer is simple. Tell him you're into mares."

"Yeah. Not like my mane isn't giving enough ponies that impression." She grumbled. "I'd rather not give them any more fuel than I have to."

"Like having to move in with a friend because of bills?" He asked.

"Exactly. Anyway… Either way you look at it. I'm going to have to…" She shivered at the thought. "Let HIM…" She quickly covered her mouth trying not to vomit.

"Well. There's always letting me take care of it for you."

"Yea. Like a twig like you has…." She blinked as her eyes were locked on his semi hard dick. "You were saying something about being single?" She asked with a gulp before licking her lips.

Smiling, Swift leaned back and pulled her closer with his wing. "That would depend on the mare I have my eyes on. She's still on the fence about me helping her with her heat."

Realizing who he was talking about, Rainbow pulled her eyes away from his dick and looked him in the eyes. "Wait. Are you?..."

"Helping with your heat? Offering to be your stallion? Getting help with my rut? Yes." He replied.

If she was able to think clearly, Rainbow would have likely caught the last part. However by the time he offered to be her stallion, Rainbow's mind was made up as she turned her attention back to his now hard dick. "I… I want to be your marefriend. I… I want you to put an end to my heat." She announced before bending over to start sucking his dick.

Leaning back, Swift let out a soft moan as he gently put a hoof on her head. "You're amazing at this." He groaned as he bit his lip. Rainbow gave a grateful moan at his compliment.

She suddenly let out a gasp as she felt his wingtip brush against her pussy. There wasn't any doubt in either of their minds. She wanted it and he did too. Pulling back she quickly got on all fours and looked back at him. "I can't wait any longer. Make me your mare. I want to feel how awesome you are at this."

Swift smiled and got behind her and gave her pussy a lick. "You wouldn't deny your lover a taste first. Would you?"

Rainbow moaned softly. "It's only fair seeing I got a taste of your pre." She replied, licking her lips. "But you better not make me wait. Or I'll be taking the leeeeeeeee-" her last word melted into a moan as she felt him mount and press the first few inches into her.

"Let's talk about that later. We have your heat to take care of." Swift replied as he slowly started to pump himself into her slowly.

At first it simply felt nice to feel him thrust into her. But as he pushed deeper, Rainbow felt her heart race with excitement and pleasure. A part of her knew that if he went deeper, the chances of her becoming pregnant went up. However it also meant that her heat would come to an end that much faster. Not to mention how amazing it felt to have him soooooo deep.

Swift felt her tighten on his dick with each thrust as if her body wanted him as deep as he was able to get and stay there. It was easy to tell that she was a virgin or at the least had used toys half his size to scratch her itches. The deeper he went, the harder he thrusted. And quickly ended up thrusting against the entire to her womb.

They both knew there was still a few inches left outside of her. And as she felt him slam against the final wall, Rainbow's eyes shot open in realization. "I don't want to hurt you or your future. But if I push any more. Then there won't be any going back." He whispered in her ear.

Rainbow knew there was still a chance for him to pull out now. But that would mean that her heat would return. With her next words, her heat would be quenched and her fate sealed. "Do it."
With a smile Swift slammed into her and ejaculated into her womb. With each thrust, he shot a load into her. It didn't take long for her belly to inflate as cum soon started to ooze out.

By the time Swift had finished, Rainbow collapsed under him with a soft, happy, and satisfied moan. Swift stumbled a little before flopping next to her.

"I think this makes us more than just lovers." She laughed. "We just need to get the papers to prove it." Hearing this, Swift smiled and nuzzled her.

"I'll trust you to plan it. Just tell me the price." He sighed softly before the two fell asleep in each other's arms.

Outside the room
Knuckles bit his lip and looked down at his erection. "And who are you jealous of, traitor?"

Look who's going to be proud parents. Let's hope others take it as smoothly as they did... maybe a little less existed?
