Lotion up Lexi

"Diddy, go start rubbing lotion on Lexi then follow my lead."

Diddy gets out of the hot-tub butt-naked and begins to rub tanning lotion on Lexi. The sight is amazing.

"what are you doing?" Lexi voices trying to look up at Diddy. She doesn't get a chance to notice you standing behind her.

"Making sure you get a good tan."

"Alright, that feels kind of good actually." She relaxes and closes her eyes. Diddy takes her hands off as if to get more lotion, but you replace her by rubbing the lotion in as softly as Diddy was.

"That feels even better Diddy, your hands feel really strong." Lexi comments, unaware you are now doing it. Encouraged, you get closer and closer to her sensitive areas, teasing her by rubbing your fingers just underneath the edge of her bikini bottoms and just below her top.

"Ooohhh, you're getting frisky Diddy." Diddy giggles next to you to sell it. While getting her shoulders you slide the bikini straps off her shoulders. You move down underneath her arm, tempting some side boob, then slipping under her other strap trying to get it to 'accidentally' slip as well. It doesn't and you meander down her body to her hips, moving the strings down as you seem to just be rubbing her. Lexi seems to be very relaxed and unconsciously spreads her legs a little bit for you. You move to her legs, rubbing lotion along their lengths. She coos at this. You spread them more open as you reach her inner thigh and her bottom again. You look at Diddy and she asks, "Trust me Lexi?"

"Keep going..."

"Keep your eye covers on. Focus on how it feels. On the rhythm of the massage and every little tingling sensation."

You hook your fingers around her bottom and slide it right off her legs. You move to her top and Lexi helps you slide it over her head. "Mmm, the summer air feels good on my skin."

You breathe across an exposed nipple.

"Ooohh..."

You move and sit next to her head while getting more lotion. Boldly, you apply it straight to her breasts. Rubbing them you play with your step-sister's nipples with your thumbs. You caress her breasts until the lotion is rubbed in. Topping that off you place a gentle sucking kiss on each nipple.

You go back to her now exposed cunt, slowly working the lotion on her inward in circles around her clit and slit. Then you rub the lotion on her as if it was nothing special and move on. She seems disappointed. You work away to her inner thigh and her lower butt, and then back to her pussy. This time taking special care to stimulate her clit and open her up. She spreads her legs wide open, you care lick her slit from the bottom up, pausing to focus on her pleasure. When she lets out a sigh of enjoyment you stop and sit between her legs your hard rod not far from her entrance. You lean forward and Diddy leans in as well.

"Do you like that Lexi?"

"Yes I do..."

"Who does it make you fantasize about Lexi?"

"You already know who..."

"Say it Lexi, and I'll make this better than you could imagine."

"John. John licking and fucking me. I'm such a dirty little sister."

"Yes you are..." Diddy trails off and you place your cock at your little sister's entrance.

The move makes her jump and take off her mask. She's shocked to see you naked and about to enter her. In her shock though she has put her legs around you, pressing your member against her. You feel her moisture and try to reassure her. "I know everything Lexi, and I want this as much as you do..."
