Road Trip (MF, voy, mast)

By FIN

My wife and I were traveling cross-country to visit 

family with my mother-in-law, sister-in-law and brother-

in-law in 2 cars. Half way through the trip my sister-in-

law joined my wife and I in our car. My wife took over 

driving and I was in the passenger seat and my sister-in-

law was in the back seat. I was tired so I reclined and 

dozed off to sleep. When I awoke I listened to my wife 

and her sister talking about sex. This interested me 

because my sister-in-law is only 17 years old and from 

what I understood is still a virgin.

The conversation continued as I pretended to be asleep. 

My sister-in-law was asking about my wife and I and our 

sex life. My wife was telling her how often we have sex 

and the type of things we like to do to each other. Her 

sister told my wife that her boyfriend wanted to have sex 

with her but she wasn't ready and that she was happy 

blowing him and giving him hand jobs but he has yet to 

give her an orgasm, because he stops touching her when he 

cums. My wife told her to just finger herself to get off 

and he should be turned on by that.

My sister-in-law then said that all this sex talk was 

getting her horny and she asked my wife if it was ok that 

she masturbate as they talked. My wife reminded her that 

I was in the car and that I may wake up. Her sister then 

said, I just need to get off and I will just stop if he 

wakes up. My wife said, ok and they continued their 

conversation.

The conversation turned to details about what I like when 

we are having sex and what I like to do to my wife. As my 

wife described what she likes to do to me I started to 

hear my sister-in-law move and I heard her start to 

finger herself. I could hear her moistness as she slid 

fingers into her pussy and she continued to talk to my 

wife but her voice changed and became more sultry and 

sexy.

My wife was explaining how she likes to cup my balls as 

she sucks and strokes me until I cum on her tits and face 

and I could hear my sister-in-law speeding up as she 

fingered herself. It was here that I moved a little 

hoping I would be able to see my sister-in-law 

masturbating. She stopped when I moved my head and I was 

still for about 3 minutes before she assumed I was still 

asleep and put her hand back in her pants.

I looked with my eyes half closed and saw movement in her 

pants as she slid her fingers in her pussy. I also saw 

her free hand under her shirt as she played with her 

nipples. Her bra was on the floor of the car. My sister-

in-law started telling my wife what she likes her 

boyfriend to do to her and what she likes to do to her 

boyfriend. She explained that she loved when she was 

blowing him to squeeze his balls to make him jump and 

that when he cums she likes to keep his cum in her mouth 

and let it drip down her chin onto her tits and she loves 

to rub his cum all over her tits. 

As she continued talking she slid her pants down to just 

below her hips and I could just make out a neatly trimmed 

pussy and 3 fingers working in and out of her pussy. She 

then told my wife that she and her friend once both gave 

her boyfriend a blowjob and her friend fingered her 

pussy. It was as she was telling my wife how wonderful 

her friend's fingers felt that she focused on her clit 

and came in a shudder. She removed her fingers from her 

pussy and licked them clean and put her pants and bra 

back on.

I pretended to wake up about 10 minutes after that. We 

were nearly at our destination and my sister-in-law asked 

if she could share a hotel room with us. My wife said yes 

without even asking me, not that I would have said no.

When we reached our destination we found a nice hotel 

that had a living room area separate from the bedroom. 

The couch had a pull out bed and my sister-in-law was 

happy to sleep on it. The only problem was that the 

bathroom was near the bed and my sister-in-law had to go 

through the bedroom and right by our bed to use the 

bathroom. The first night went by without any situations, 

I think we were too tired to do anything. But the second 

night was more eventful.

We had spent the day visiting family and ate dinner out. 

We returned to the hotel around 8 PM and relaxed and 

watched TV. Around 9:30 my wife yawned and said she was 

tired and was heading to bed. She asked me if I was 

joining her with a sexy smile. I knew what she had 

planned and did indeed join her. Her sister was laying on 

the sofa-bed and said goodnight. 

We laid in bed until my sister-in-law turned out the 

light in the other part of the hotel room and turned off 

the TV. When my wife was sure her sister, Brooke, was 

asleep she turned over to me and kissed me. After she 

kissed me she told me that during the car ride and when I 

was asleep her sister asked her all about our sex life 

and told her about her sex life.

My wife continued, "She told me that she has never had 

sex, but has given blowjobs and loves cum on her tits and 

face, I guess it runs in the family," and she giggled. 

She went on to say, "She also told me about she and a 

girl friend of hers had a 3some with her boyfriend, can 

you believe that? But it gets better, while she was 

telling me this, she was masturbating in the back seat of 

our car. I heard her juices and her fingers swishing away 

in her twat. It got me so horny, but I was driving, 

otherwise I would have fucked you right there with her 

watching." 

I acted surprised even though I wasn't surprised at all. 

While my wife was telling me what happened her hand had 

moved to my dick and was stroking it through my pants. My 

wife went on and asked if I would mind if she told Brooke 

about how we swing and maybe she would like to join our 

swing group. I told her I wasn't sure that was a good 

idea, I mean how would she like it if I ended up fucking 

her sister?

My wife said that she wouldn't mind and that just the 

idea of it was making her wet, with that she slid her 

pants off and slid 2 fingers into her pussy and brought 

those fingers to my mouth to show me how wet she was. I 

sucked her fingers dry and slid my pants off. My wife was 

now totally nude and had her legs spread wide and was 

fingering herself while she watched me get undressed. I 

told her that her sister was in the same hotel room and 

that she could walk in on us anytime. To which my wife 

replied, " good then you can fuck her tonight." 

Hearing her say that made my dick jump and she grabbed me 

by my dick and pulled me to her. Her mouth opened and 

took me deep into her throat. She sucked my dick for a 

bit then sat up on her hands and knees and told me to 

fuck her. I moved around behind her and slid my cock up 

and down her pussy to get it nice and wet. When I was 

convinced she and I were wet enough, I rammed forward 

into her pussy. The force of it knocked her head first 

into the bed's head board. There was a loud thud and as 

she regained her position she said, "Yes baby, fuck me 

hard, make me cum."

I was fucking her pretty hard, my balls slapping her and 

I guess we didn't realize that the sound of our bodies 

pounding against each other was loud, or we knew it but 

didn't want to stop, but Brooke must have woken up. She 

burst through the door and said, "What the fuck are you 

doing?" Then she saw us and realized, she started to 

apologize and said, "sorry, I thought you were hitting 

her, it sounded like it and oh geez, sorry." As she 

started to leave my wife told her to stop. Brooke stopped 

in the doorway.

My wife stood up and took her sister's hand and brought 

her to a chair by the bed. My wife said, "You asked me 

about sex the other day and I told you some of the things 

that he likes and that I like, but what I didn't tell you 

is that we like people to watch us have sex, and to tell 

us what to do to each other. Would you like to do that 

for us tonight. You don't have to take your clothes off, 

but I am sure that he wouldn't mind if you wanted too. If 

you don't want to do any of this you don't have to but we 

get so turned on when we know someone is watching us. So, 

the choice is yours."

With that my wife came back to the bed and took my dick 

in her mouth and took me deep, her nose hit my body. She 

went down 2 times then with just the head of my dick in 

her mouth she looked at her sister, who just nodded her 

head that she was going to stay. 

As my wife began sucking my dick again Brooke spoke and 

asked if we would show her how my wife gives me a hand 

job. My wife repositioned herself on the bed sitting 

Indian-style and I put my legs on either side of her and 

my wife told Brooke to come closer so she can see exactly 

what my wife was doing to me. She explained how she puts 

her palm under my balls and cups my balls as she uses her 

other hand to stroke me. My wife also explained how easy 

it is to lean over and suck my cock as she strokes me. 

Brooke just watched as my wife stroked my cock and 

intermittently sucked me. I looked at her and she was 

watching intently and licking her lips. She looked at me 

and blushed a little. She looked so sweet sitting there 

completely dressed as she watched her sister give me a 

hand job. Brooke then told us to show her how we 

masturbate for each other. My wife just laid back and 

spread her legs as I took over stroking my cock. My wife 

used both hands to spread her pussy open and rubbed her 

clit and slid 2 fingers right into her pussy.

Brooke sat on the bed in on the side of us but in-between 

us and watched as my wife fingered her clit and as I 

stroked my cock. My wife then spoke and told Brooke that 

we were swingers. Brooked looked confused but didn't say 

anything. My wife then asked her if she knew what a 

swinger was, Brooke just shook her head no. My wife 

explained to her that we get together with other couples 

and have sex with anyone we wanted, other couples, other 

singles etc...

Brooke looked surprised and my wife told her that she 

wouldn't mind if she touched me or her and that Brooke 

should strip if she felt comfortable and join our fun. 

Brooke said that she just wanted to watch for now and 

asked me to eat my wife's pussy.

I moved between my wife's legs as my wife spread her 

pussy wide open and I assaulted her clit and pussy with 

my mouth, tongue and fingers. I sucked and nibbled her 

clit as I fingered her pussy with 3 fingers. I was 

concentrating on my wife when my wife pulled my head from 

her pussy to show me her sister sitting in the chair 

fingering her pussy as she watched us. Her body was much 

nicer than I thought. She hid her body well in the 

clothes she wore. She is about 5-6, maybe 110 lbs but she 

looked much heavier in the baggy clothes she wore. She 

has small titties maybe the size of tennis balls but with 

hard pointy nipples. As she fingered her pussy she used 

her other hand to pinch and pull her nipples. 

I told my wife to get on her hands and knees again and I 

slid my cock into her pussy as I watched Brooke 

masturbate as we fucked. Brooke watched as I pounded my 

wife from behind, Brooke was sliding 2 fingers into her 

pussy then looked right at me as she raised the fingers 

to her lips and sucked them like a small dick.

This sent me over the edge and I pulled out of my wife's 

pussy, moved her to her back and jerked my cum all over 

her tits and face. I rubbed my cum on her tits as Brooke 

fiercely rubbed her clit and started to shudder and moan. 

My wife watched as her sister had an orgasm and 

masturbated to an orgasm as she watched.

Brooke, my wife and I were all naked in the bedroom and 

were all sweaty and hot. I turned on the air conditioner 

and told them I was going to refresh in
