Motherfucker: Part 3

... of the bed, I had the perfect view of their two genitals getting ready to couple up. And when I saw Greg's penis slide all the up inside Jenny's vagina, she reacted as if she were a young child on a ride at Disney World. In other words, she was the very definition of the word, "giddy."

And when he began thrusting away very slowly at her vagina, she couldn't stop talking to him. She was telling Greg about how great his dick felt inside her, and she asked him if he would fuck her in front of their mother sometime.

Greg nodded his head as he kept slowing thrusting away at his little sister's vagina, and I could tell from the way that he was thrusting that something wasn't quite right.

At this point, Greg had made maybe four or five slow forward thrusts, at the most. And then I saw his perineum area and his asshole sphincter start rhythmically pulsating as he just kept on slowly thrusting away, and I assumed that he was trying his best to hide the fact that he was already ejaculating inside Jenny's vagina.

But Jenny must have instantly sensed it when her vagina suddenly got wetter, because she asked Greg, "Are you cumming inside me already? I can't believe it! I thought you'd last at least a couple of minutes this time around. But I guess I was wrong."

"I'm sorry, sis! I don't know what's wrong with me. You just get me too excited, and I can't keep from cumming, and--"

"--Look at me!" Jenny said sternly cutting Greg off to intentionally interrupt his ...

... excuse-making.

And then Jenny added in a very calm and nurturing tone-of-voice. "I'm not upset with you for getting super-excited about having sex with me. Actually it's quite flattering. And there's nothing wrong with you that a little bit of time and patience won't cure. But hey, look at the bright side. At least this time, you're releasing all of your sperm

inside

my pussy. Now that's an improvement, isn't it?"

"Yeah, I guess it is," Greg half-heartedly agreed, while he continued to slowly thrust his still-mildly-throbbing penis in and out of his little sister's baby-making hole as his sperm-release was naturally tapering off.

Then Greg stopped thrusting and collapsed on top of Jenny, and he started crying like a little baby, as he kept apologizing profusely to her.

"What the fuck, Greg!" Jenny rebuked him loudly. "Man up, God damn it! Either that, or get the fuck off of me right now and go home. I'm sure I can catch a ride home later with someone here."

"You bet," Mom chimed in. "I'll be more than happy to give you a ride home later."

Greg's response to all this was to get up out of bed, still apologizing to Jenny the whole time. And he quickly got dressed, and then took off down the stairs to leave without even saying goodby to anyone in the room.

We all heard the tires of his Volkswagen Beetle peel out at the curb in front of Mom's house, when he gunned the engine and took off down the street like a bat out of hell.

We all just looked at one another ...
