Just a Little Experiment

Warning: Sex/Impregnation

Alvin still felt odd from the blue elixir that Simon had given him, he didn't even know what it was for but he drank it anyway. All Alvin remembers is Simon saying "Its just a little experiment" he also said that Alvin should go and meet with Brittany but he was tired so he just headed back to him apartment.

When Alvin reached his apartment and tried to unlock the door he noticed it was already unlocked, he slowly creaked open the door and went in. As Alvin slowly and carefully searched every room until he came to his bedroom, he opened the door and stared in silence at what he saw, there sprawled out on the bed was Jeanette, she was wearing a black dressing gown that was undone in the middle so you could see her bra and belly.

Alvin swallowed and said "J-Jeanette what are you d-doing here"

Jeanette slowly got off the bed and walked up to Alvin, she pushed the door behind him closed and she whispered "Don't you like me Alvin?"

Alvin replied in a quite voice "W-what about Simon I could-" She cut him off by putting a finger on his lips, she then whispered to him again "I want you, not Simon" Alvin could feel the heat begin to rise in his lower area and he tried to stop her

"I-I don't have a condom" said Alvin, hoping that would steer her away but instead she whispered

"You can just pull out, now come with me" She lead him over to the bed and sat him down, Alvin leaned back and watched her slowly undo his pants, his rock hard cock came out in front of her face and she began to slowly suck the end of it.

Alvin writhed in pleasure at Jeanette worked her lips and tongue, she started to speed up and go deeper until Alvin started to make louder moaning sounds, she stopped knowing he was close, Jeanette pulled his cock out of her mouth and she panted looking up at him with her blue eyes.

Alvin was lying on the bed when suddenly felt the weigh of Jeanette on him, he looked up and his eyes opened wide as she was now completely naked and cupping her breasts in her hands, she closed her eyes and slid onto him. Alvin was now powerless as Jeanette started to slide up and down on him, she moaned in pleasure and eventually Alvin joined in by holding her hips and moving her up and down. Alvins balls were still inside his pants and neither of them noticed they were pulsating and glowing blue, Jeanette moaned louder as she felt Alvin go even deeper into her, Alvins cock suddenly pierced into her womb and she let out a cry of pleasure. Alvin suddenly felt himself reaching the point of no return and as he was about to tell Jeanette she leaned in and kissed him deeply, she kept riding him and then they both climaxed at the same time causing Alvin to fire his sticky load deep into her womb. Jeanette collapsed to the side of Alvin and fell asleep, Alvin didn't fall asleep as he felt he still had more, he faced her and entered deep into her womb again, he slowly fell asleep as he felt his cock pumping out more seed.

Alvin was awoken by Jeanette, when Alvin awoke he saw that Jeanette was pointing to her stomach which was now rather plump, suddenly Jeanette let out a groan and he belly started to move, Jeanette panicked as she saw something moving inside her.
