Lexi is uncertain.

"Now you've seen what you're in for. Still interested in letting your older brother fuck your brains out?" You ask Lexi.

"That was pretty hot!" Lexi answers

"Oh, it was. Your brother's cock felt good inside me." Diddy comments

"I don't know if I'm up for doing that though..."

"We can do it any way you want Lexi" you answer.

"I wouldn't know where to start..."

"That part is easy Lexi." Diddy answers.

"It is?"

"Sure! John get over here. Let's show Lexi what each position is. You already saw us fuck Doggy-style." Diddy lays back on the pad next to the jacuzzi and spreads her legs open with knees bent. "It can be fun, but it's harder to get off." You move over to her laying yourself against her. You rub your flaccid cock against her opening and she smiles. "Okay, this is missionary. Probably the easiest. But not very fun."

She then wraps her legs around you and says, "It's a little more fun when you grab him with your legs." This rubs her against you even more and you feel yourself getting harder. You then lean back and lift her legs up to your chest. "You can do this to, he'll feel a lot bigger inside you, but I don't think it's good to start with."

Diddy sits up and pulls you towards her. "Now sit here John." She indicates next to where she is sitting. You obey and your now hard again rod is standing at attention. "Well look what we have here Lexi." She says. "He's all ready for you." Lexi blushes while Diddy sits on your lap looking away from you. "You can sit on him like a lap dance." Looking at Lexi she teasingly grinds against you. She starts giving you a little lap dance and raises her arms up and over her head. You reach around her and start playing with her breasts and kissing her neck.

"Down boy." Diddy pushes your chest back making you release her and lay down on the cushion. She starts straddling your twitching cock and has it rest along her slit. "This is the reverse cowgirl." You have more control over how much you let him penetrate you this way. she rolls her hips against you, teasing you even more. "Damn girl, you are cruel."

She ignores you. "Okay, one last position Lexi." Diddy just turns herself around, facing you, "This is pretty much the same, but let's you look at each other and let's him play with your tits. You play with Diddy's nipples as she explains this to Lexi. You also start pushing up at her with your hips.

"Well babe," Diddy says "He's as ready as ever, and if you don't fuck him fast, I think I'll have to!"

Lexi stands up and kneels next you, still looking uncertain. You reach up with your right hand and start rubbing around her pussy. "I promise I'll be gentle lil sis."

Diddy dismounts you and gets close behind her. "He's all yours..." She says as she caresses her best-friend's naked body.
