I've been watching threesome videos lately. MMF threesome videos. I knew I've seen this one before, but it's definitely an interesting case study.

The video starts off with a guy and a girl. They seem familiar. Maybe girlfriend boyfriend. Sex ensues, but they're clearly waiting for someone else to show up. The first guy is chubby, short, and he leaves his shirt on throughout the video.

Then at 2 minutes Chad McThunderloins shows up. Tall and muscular.

I have to tell you something I've noticed from watching threesome videos. Women well let anyone fuck them. It's not big deal. They get something out of it. They only want to blow the guys they really like. They're only hungry for their dick. Affection they can only give to the guys they like. She readily eats McThundercocks face as soon as she shows up.

The inital positions start. Chubby his fucking her, and Mcthundercock is getting his dick sucked. They switch, and then switch back. There are a few things I want to point out.

1.) @2:58 she moves up into the primary position throughout the video. Sucking one guy off while getting fucked by the other. Look at her body, most notably her thighs. They're leaning forward into McThunderfuck.

2.) @2:58 when the other guys starts to fuck her, she doesn't react, she just keeps sucking McThundercock's dick to the best of her ability.

3.) They switch positions @4:10. She looks up at McThundercock and asks him if he wants to fuck her, and they switch. But now, look at her body orientation now. She's leaning back into McThundercock. Compare the body orientation of the two @3:05 and @5:05. It's completely different, and it's obvious who she's leaning into.

4.) @7:40 He starts fucking her a little harder, and she completely abandons the other guys dick. How do things look at 7:55? She stops sucking the chubby guys dick several times during his turn for dick sucking, but she never stops sucking McThundercocks dick. From @2:22 to @4:15 and @9:02 to the end she doesn't stop sucking him off for more than a second.

5.)Who's getting blown better? Watch @9:20 till @9:50 and compare it to @7:00 to @7:30 and you tell me.

6.) But, if you don't want to watch all of that, or don't believe it, just watch the end. Watch from 11:55 till the end of this video. She stares at Chad McThundercock like she's in love. She doesn't acknowledge chubby at all. And @12:55 McThundercock announces that he's "gotta go". And that's that.
