Tick Of Royalty

A few days of progress go by and you wake up in the morning to Shining Armor licking and kissing your neck affectionately. He looked up at you, smiling nervously. He had a loving look on his face as he moved closer to your face and locking lips with you. You felt yourself almost immediately tense up, but quickly relax, shakily kissing back.
The kiss goes on for well over ten seconds before you come to your senses, pushing the prince off of you. You explain that you feel dirty doing this to the princess, trotting away and leaving him alone with tears streaming down his face.

"I- I thought we had something... A spark... Ch- Chemistry..." He puts his head in his arms and begins to cry. About three minutes later you trot back in to the room with pancakes and see the sobbing mess of a stallion. You look at him and set down his breakfast, trotting toward him. He shies away from you. He notices the tears in your eyes, running into your arms. He buries his face in your chest fluff, sobbing lightly. You apologize over and over again, kissing his head after each apology. Eventually you both stopped crying, and exchanged it for cuddling.

"D-do you think we could try that k-" you interrupted him by locking your lips together. He jumped, surprised, but happily kissed back. You caught him rubbing your stomach lovingly, letting him continue with what he was doing. You sat down and leaned back so he could do what he so wished.

He proceeded to drag his feline-resemblant tongue against your large, musky balls. You groan lightly as he works his way around your length, licking around your urethra before he takes your sensitive twenty inches into his mouth. You want to scream in pleasure, but know you probably shouldn't because it's early in the morning. He begins bobbing his head, dragging his lips back and forth against your medial ring, milking your member and slowly getting you closer and closer to climax and then--

He stops. Just before you get off in his throat.
"I can't have you finish just yet..." He turns around, baring you his voluptuous plot, shaking it before rubbing his ponut against your tip, giggling. "You ready, big boy..? He snickered, and not waiting for an answer, plunges down onto your cock. Suddenly you find yourself to have an unbelievable head rush as the white stallion sits on your throbbing member and moans. "S-so big.." He placed his hooves on the bulge in his stomach, beginning to bounce on your shlong.

You felt the load from your previous playtime rushing back, slowly, but definitely surely. Shining spun on your cock to face you, wiggling his junk in your face. You knew very well what to do with that. As you leaned forward to take the prince's throbbing ten inches, he thrust into your mouth, still bouncing on you. You felt yourself on the verge of delightful climax, when Shining gives out, cumming a few ounces into your mouth. You smile, popping the prince out of your mouth. You warn him in advance. You finally reach your intense, horse-sized climax, filling the gentile prince's stomach. You pant as he pops you out, obviously stretched out.

"One more round...?~" he laughed and fell into your lap, rubbing your members together. He moaned a bit as he rubbed his distended stomach. He yawned, exhausted from the sexual activity.
You ask if he's tired and he nods lightly.

"Can I sleep on you..?" He yawned and looked you in the eye, still rubbing his gut. You nod, smiling at him. He giggles lightly and falls asleep. You look to his still steaming plate of breakfast, thinking that he should eat.

(This is where the gain comes in.)

You gently set down the prince, trying not to awake him, trotting over and getting his food. You trot back to the bed, laying him back down on you expertly and begin to feed him in his sleep. He remains in a doze, if not going into a deeper sleep. He moans like before as his stomach fills. You smile and snuggle him, rubbing his gut lovingly.
