Incest Is Indeed Best!

I don’t know when Sam left my room, nor do I know when I drifted back to sleep or dressed in jeans, but I know when a pair of lips are working my cock. I opened my eyes but it was still sleep addled. I was waiting for my eyes to adjust when I happened to notice Mandy’s favorite stuffed tiger on my bed. If it was here then does that mean?

Instantly after blinking a few times my eyes focused and there was my baby sister sitting between my legs still dressed. “What the hell do you think you're doing?”

Mandy just sat there on her shins. Then she tossed up her hands, “So when it’s Sam sucking your cock, that’s alright but when your own sister wants to get closer to you, suddenly it's wrong!”

I went to say something when Mandy blurted out, “Haven’t you heard, Incest is best!”

“Maybe for some but not for me it isn’t!”

Then Sam stuck her head in through the open door, “Oh just let her blow you and she’ll promise to leave you alone after that. Great it would appear that the two of them were in cahoots with each other in this.

Fuck I figured that if i let her suck my cock that it would end everything- how fucking wrong was I!

“Oh Jesus Christ, if it will make you leave me alone, suck my cock then!”

Mandy jumped up off the bed and took off her top and jean shorts. Clad only in a bra and matching thong, Mandy returned to sucking my cock and I actually started groaning. Christ, I never knew that my younger sister had such a cocksucking talent.

Of course it didn’t help any that Sam kept commenting on what was going on! But I wasn’t going to use that as an excuse about why I pushed Mandy off my cock tore her bra and thong off her body and positioned her on elbows and knees.

I got behind her and after aligning my cock I drove it deep and fast into her pussy. Mandy started biting the pillow near her mouth to prevent her from crying out as I fucked her hard. Over and over I thrusted in and out of her pussy until Mandy had no choice but to lift her head and cry out

“OH MY GOD BIG BROTHER YOU’RE FUCKING ME WITH THAT BIG COCK!”

Then I heard Sam from the doorway, “Doesn’t he make you want to fuck him every chance you get?”

“OHGODYES!”

Then I pulled my cock out of her pussy and flipped her over onto her back. Mandy held onto her right leg while I had her left legs spreading her wide so i could continue to fuck her.

A few more thrust and I came like a freight train in my baby sister’s pussy!

Then Sam made it feel so wrong to me. “See Mandy, I told you your brother really knows how to fuck a pussy!”

Then Mandy replied. “Yeah your right, now get out of her so he can fuck me some more!”

Sam left and I got back to fucking Mandy in various positions!
