Writes desires to always be impregnated by her brother when not pregnant on Becca’s leg.

“I want you to pump me full of that nasty **** sperm!” Becca growled as she started to move her hips faster. “Breed me! Make me your little prego slut!” She moaned as her eyes took on a fevered gleam.

Matt felt a little confused as he looked at his sister. He thought about stopping when he felt something on his leg. Looking down he noticed Randy had the pen in her hand. Suddenly he felt a strong desire to do what his sister had asked. ‘I should impregnate my sister. In fact, I should impregnate all my female family members.’ He thought as he focused back on fucking Becca.

Randy giggled as she watched the ink saying desires to impregnate all his female family members on Matt’s leg disappear. Randy sat back and stroked her cock as she watched the two siblings start to work each other closer to climax.

Becca screamed louder as her pussy clamped down on Matt’s dick and her body spasmed in orgasm. The extra sensation was enough to push Matt over the edge and he groaned as he filled his sister with his cum. When their orgasms ended Matt noticed his sister looked a little sad and asked. “What’s wrong?”

Becca sniffled a little as she blinked away her tears and said. “I wish I wasn’t on my birth control. It’s going to take longer for me to get pregnant.”

Matt gave his sister a reassuring smile and said. “Don’t worry you are going to be pumping out my kids in no time.” Becca realized he was being serious and felt closer to him then she ever had before. She kissed him passionately as she felt something she never had with anyone other than her sister.

When Matt broke the kiss, he saw a look in his sister’s eyes he had never seen before. If he didn’t know her any better, he would swear she was in love with him. He set Becca down on the floor and she pushed him back into the couch making him sit down. Before he could ask what she was up to she crawled onto the couch next to him and started to suck his dick.
