Your cousin Lizzie

The beautiful blonde has a shocked look for a moment and then calms down when she realizes it's you. You smile inwardly and outwardly. Lizzie returns the smile and then goes back to showering. She never was the brightest bulb. You quietly walk up to the shower and step inside.

"What do you think youre doing?"

"Taking a shower with my cousin Lizzie... we used to do it all the time..."

"That was when we were kids... now were old enough to have kids of our own... it's not right."

"Seems pretty all right to me..." you say and begin to slowly stroke your rod in front of her.

"Um... why are you doing that?" she says quietly while soaping herself. Her eyes are locked on your cock as your hand slowly strokes up and down. You can see her hunger for a moment before she looks away.

"Can't I enjoy myself around a beautiful woman? I mean... it's not like we didn't watch each other do this when we were younger..."

"Um..." her eyes return to your stroking, "we... we were different then... we werent old enough to have sex then..."

"Who said anything about sex," you say disarmingly, "I just want to rub one out while I watch you do the same..."

She shivers slightly and you see her hands have already stopped simply soaping her body and have turned to pleasuring it. Her hands gently kneading her breasts like dough. Her hands gently run down her hips and slide between her legs to her furry snatch. You see her frig away at her clit, her juices frothing slightly as her pleasure increases. She bites her hand to keep from screaming as she climaxes, her body shuddering heavily with her release.

She almost collapses and you reach out to help her and her chest presses wonderfully against you. You hold her for awhile and let her calm down a bit before she looks up and kisses you greedily. She pushes you down to the shower floor and spreads her legs over to straddle you. Your dick stabbing massively in the air as she lowers her sopping cunt down onto your rod.

Her legs start to raise and lower her on your cock and she moans softly as it slides in and out of her tight little box.

"I don't understand... why I am so... gasp horny... pant" her breasts bounce deliciously in rythm with her movements. "Im usually only this horny when I ovulate..." she blushes at her confession but doesn't stop her ride.
