My heart still pounds as I'm writing this. First off, my sister-in-law has always been a bit standoffish with me. Never really rude, but just...haughty, I guess. And oh yes she is a hotty! She is 5'5", Latina, with light skin and light brown hair and eyes. Full lips, small tits and an amazing lithe body with a juicy ass.

Anyways, my wife and I were going out for dinner and drinks with her sister Gina and Gina's husband. I get along great with her husband Mike, otherwise no way on earth I would have gone out with them!

Cut to the chase, after dinner, we are all tipsy. I'd never seen Gina so tipsy before, I asked Mike if he was okay to drive and he nodded yes. We get to his car and I open the rear passenger door for my wife. She bolts to the front passenger door instead, calls shotgun and hops in. I tell my wife that Gina should get in front since Mike is driving, but she just laughs it off. I look over at Gina and give her a 'fuck I have to sit next to you' face.

By now we're on the road, my wife is drunk passed out and her head is bobbing with every slight turn and brake. Mike is concentrating on the road when I feel a hand on my thigh. I almost jump out of my skin it's so unexpected! I glance over and Gina and she has a look in her eyes that I've never seen before. I panic, put my hand over hers and move it off of my leg, thank you. A few seconds later her hand is back on leg, and now she's rubbing up on my thigh. I glance over at her again and she is looking at my crotch. I glance uneasily at Mike, thank goodness it's nighttime! Gina's hand moves to my crotch and starts rubbing my dick through my slacks. My dick is starting to grow now and I'm glancing at Mike every few seconds. Next Gina grabs her sweater and places it over her arm and my crotch. I feel her tugging at my zipper and I'm looking at her like 'are you fucking crazy'!!?? She slides her body down and lays her head against the back of the seat, closing her eyes. I catch on to her game now and I lay my head back on the headrest so that it looks like i'm sleeping as well.

My zipper is now down and she's working the clasp of my slacks. She frees it, and I feel her warm hand reach inside my boxers. God it feels so good, and the eroticism of having my dick in her hand as her husband is driving makes me want to explode. She is slowly rubbing my dick up and down in a sensual manner, enjoying the sensation no doubt of having a strange dick in her hands. Her fingertips rub the underside of my shaft and my cock is twitching it aches so bad. I desperately want my dick in her mouth and I'm starting to think with my other head.

Her fingertips drift over the head of my cock, around the rim of my head, up and down the sides, top and bottom of my shaft. It's almost as if she's using her fingers as eyes to take in every inch of my cock. I'm starting to leak pre-cum now...a lot. She feels my pre-cum as well and her fingers circle over the tip of my pee-hole and she spreads my cum on the head. The tip of my cock is a bit moist and she concentrates on the tip. God it is a slow tease and I slightly buck my hips. Looking at Mike, he' still concentrating on the road. I look at Gina, she pulls her hand out and I'm half-relieved and half-disappointed. I figure she just wanted to tease me, but no...she licks her hand up and down slides it back over to my cock. Fuck!! It's wet and warm and she starts to jack, trying to spread her spit on my dick. It's not wet enough..she pulls her hand out again, discreetly spits in it, and back her hand goes onto my cock. My cock is now slick with her spit and she is jacking the tip of my dick, cupping it in her palm and stroking up and down. She also is twisting her hand slightly and the sensations are fucking amazing. I've never been in this situation before...but it's hot as hell.

This is going on for a few minutes although it seems like an eternity. I'm expecting Mike to catch us at any second...boy would our relationship change! I so desperately want to buck my hips and moan, feel up Gina's ass and pussy. I feel like a prisoner to my lust.

I feel movement in the seat and look over at Gina. She is now lowering her head, making it look like she fell asleep in my lap. I see her adjust her sweater to cover her head a bit, she pulls my dick sideways, and next I feel her warm lips on the tip of my dick...fuck! Her tongue probes my pee-hole then begins to swirl around the tip. She is oh-so-slowly jacking me while doing this when suddenly she swallows me half-way. She is sucking and twirling her tongue around the underside of my cock while her fingers also work the underside of my shaft. My cock twitches once, twice, I feel a warm sensation come over me, and I know I'm about to cum. How can I warn her? I can't say anything for fear of Mike hearing. Instead, I keep silent...I figure she knows a guy is about to cum when she feels the dick start to pulse. I'm right. She senses it, and her tongue starts to move quicker on the underside of my shaft. Pulse, squirt. She catches it in her mouth. Pulse, squirt. Add to the collection. Pulse, squirt again, and I feel a bit of cum leaking down the side of my leg.

A few more twitches and I'm done cumming. She keeps her lips on the tip of my dick and massages the last drops of cum by continuing to rub the underside of my shaft. Done, she resumes her sleeping position and I zip myself up. We get home maybe 15 minutes later and she plays it off good.

We're getting together again this weekend for a family event and now I'm dying to see her reaction...
