The couple maintained this lustful rhythm, Alyssa kneeling submissively and stroking his cock with her talented mouth. She swallowed occasionally, clearing the saliva from her mouth and massaging his cock with the strong muscles in her throat. John could only moan appreciatively as the talented girl deep throated him time after time.

“Uhn, Uhn, Uhn!" he groaned in time to her bobbing head.

This blowjob was amazing, even better than last night. The girl seemed quite determined to milk his balls. John recalled a vision of Alyssa stroking her swollen belly yesterday and struggled not to come instantly.

Alyssa seemed to be reading his body perfectly and sensed the rising ecstasy growing in the man she was servicing so amazingly. Her throat gripped him comfortingly as he throbbed in her mouth, her lips soft, yet insistent as they travelled down to his root time and time again. Subconsciously sensing that he was ready, the girl drew back, clearing her windpipe and allowing her to take a deep lungful of air. Her body rejuvenated, she slid right back down his length again, her body promising him relief.

The change in sensation was too much for John and he gripped the armrests of his chair in a fierce grip as he threw his head back and exploded.

"Oh fuck me! I'm coming!!" He bellowed, as his quad prepared for action.

Massive spurt after spurt of gloriously rich spunk blasted up his shaft and into the welcoming pit of Alyssa's stomach. John's hips thrust forward in rapid reflexive motions, as he desperately unloaded his cum into the willing girl prostrate before him. Alyssa's soft full lips cushioned his thrusts as she leaned forward, eagerly sucking on him and taking his huge Load.

The pretty teen's slim belly soon began to round out, as John filled her with heavy spunk. Alyssa's throat throbbed in sync with his cock as his jism race up his huge shaft and pulsed into her body. Her mouth and throat fitted his length like a hot, tight, pussy and John's body did its best to inseminate her. The young woman's body trembled as she joined him in mindless orgasm, her body revelling in being used so completely.

Eventually John's mind blowing orgasm abated. Alyssa pulled back, letting his cock slip from the tight confines of her throat until only his head remained in her mouth. He could only shudder as she sucked powerfully on him one last time and his spent balls desperately tried to feed her more cum.

"She looks Like the cat that got the cream." John thought to himself, as he sighed with relief.

Alyssa let him go and leaned back, a self satisfied smile on her face. Speaking of which, his cream had filled out her tummy nicely. The petite waif was stroking another bellyful of the rich, semen Laden cum that had settled warmly in the welcoming new home of her stomach. The massive load had given her another swollen belly, just as Large as that of the previous night. On her slim body it Looked obscene.

Alyssa's eyes were heavy lidded and still glazed over, so John got up, scooped the slim girl up in his arms and carried her back to the passenger cabin. She sighed contentedly into his chest as he walked back to her room. He marvelled at her light weight, despite the extra load he had just added to her rounded midrift and was able to carry her effortlessly. He gently laid her out on the bed, returning a moment later to cover her slim form up with the sheet.

John busied himself with routine maintenance in the ship. After relieving his baser urges, he was now able to concentrate again and he hummed happily to himself as went about his chores. Some power cabling resealed here, an overhead light fixed there, time seemed to disappear as he worked on the ship. Several hours passed and John had just finished cleaning the recreation room when a noise behind him brought him back to full awareness.

“Ahem!" Alyssa cleared her throat, announcing her presence.

“What did you do to my tummy?" she demanded, as he turned to face her.

Alyssa was stood, hands on hips, in the entrance to the rec-room. As she strode towards him, he saw that the object of her indignation had reduced in size somewhat from when he had initially filled her up. Unfortunately her body had not had enough time to absorb the heavy, protein rich spunk and the petite girl still looked several months pregnant.

"You look amazing Alyssa." John reassured the girl as he moved towards her, momentarily regretting his pledge not to knock her up.

He gathered her smoothly in his arms, leaning down to kiss the surprised teen full on the Lips. She sighed a breathy moan as her soft, pouting lips parted to let him push in his tongue. They kissed passionately for several moments, her own tongue moving to duel his in her mouth. John moved to the sofa, gathering the girl in his lap as he sat down, maintaining their kiss and fierce embrace.

The couple paused for breath and leaned back, studying each other. John moved his big masculine hand to the teens stuffed belly and stroked her gently. Her stomach felt firm and full where his heavy spunk had blown out her waistline, forcing her slim tummy to accommodate his load. He thought about the millions of sperm swimming around inside her. desperate in their futile task to impregnate the slim teenager and he felt a stirring in his Loins

"I explained that I fed you several pints of cum Last night. This is what it looks like." John caressed Alyssa's engorged belly pointedly.

“I thought you were exaggerating." Alyssa mumbled, embarrassed.

“Don't worry, your body will absorb it all and you will be back to normal in no time." John reassured the worried girl.
