Part 1: https://www.reddit.com/r/sexstories/s/4Kw23vL4za

In the first part I described how, during the first half of a boring 'erotic' movie, my kinky girlfriend spiced things up with a French woman sitting next to her in the cinema. Non-sexual oral communication is difficult, the woman and her husband only speak French, we don't.

During the break, the French couple (who now introduced themselves as François and Yvette), my girlfriend and I get some drinks and use the restrooms. When my girlfriend returns, she is obviously in a very seductive mood. What have the two women cooked up together?

Yvette and my girlfriend, in the women's restroom, managed to communicate by drawing lipstick images on the mirror. Yvette drew a picture showing that not all sex positions are achievable between her and François due to weight and medical issues. My girlfriend, always looking for a spicy adventure, suggested a partner swap during the second half of the movie to which Yvette responded with eagerness. She 'told' my girlfriend that she craves to be fucked in prone position. She also would like it rough. Banging the sensitive areas deeper inside the vagina around her cervix would mean a big bonus to her.

Yvette is now talking to François about a possible partner swap and my girlfriend already has some creative ideas she'd like to try out on this guy so it's really up to me on our end.

Well, that's easy for me. If she wants it and everyone involved is on the same page, I'm game. It's the rough part that I'm not too comfortable with, especially with a strange person, but I'll surely try make it worth her while. I wonder what the cleaners wil think finding those drawings on the mirror.

We look at Yvette and her husband, who signals his full agreement giving us a thumbs up. Together we move to the back row, which does not have individual folding seats. Instead it has a bench with removable arms rests. The cinema is more than half empty now as people apparently left and we find the back row completely empty.

No one can see what we will be doing here as long as we stay low, my girlfriend says (remember these were the 1980's when night vision cameras and security guards, at least in Europe, were uncommon in cinemas. Also this I not a high end movie theatre but more like a local holiday-area cinema with perhaps a somewhat shady reputation). Additionally, judging by the sounds around us before the break, most people present already were banging their partners instead of watching the movie so wouldn't pay attention to, or be annoyed by, our activities.

My girlfriend always has a collection of condoms of different sizes in her purse and checks with Yvette picking the right size for her husband. She gives Yvette some in my size. As the lights go dim and the movie resumes my girlfriend immediately removes her dress and kneels down on the floor fully naked between François's legs, lowering his pants. I can tell she's eager to try something new.

Yvette sees this too and smiles at me as she pulls of my shirt. She removes her top showing me her voluptuous boobs en places my hands on them. Yvette now looks much hotter than before, I long to pleasure her. Her breasts feel surprisingly firm and I kiss the nipples to arouse them and make her feel comfortable with me. To me, it's important that she feels good with me. We forget all about the movie while kissing and caressing. Yvette's confidence and excitement increase, she really gets in the mood and demonstrates this by taking off her jeans and panties. When she places my hand on her wet pussy I caress the curvy lips and let a finger slide in between them to stimulate her inner labia and sensitive entrance to deeper pleasures. This woman is really hot and eager now. I feel my precum starting to ooze out as my throbbing cock lets me know what it wants.

Yvette powerfully pushes me down on the couch, aggressively straddles me, proudly displaying her naked chubby body in the dim light. Without further ado she moves forward shoving her wet pussy straight in my face. I grab her hips and pull her lips firmly against my mouth, letting her feel my eagerness in response to her aggressive desire. With my tongue I find the labia and clit which lies hidden between the folds and start pleasuring her as best I can, sucking and licking while using my hands to spread her ass and increase stimulation by teasing her ass cleft to which she responds with soft moans. Yvette's responses make me feel confident.

From the corner of my eye I see François lying on his back on the floor with my girlfriend sucking his cock. He's fondling her empty saggy titties which must be a totally new experience for him. When my girlfriend notices I'm looking, she defiantly goes down on him taking the full length of his cock firmly in her mouth and throat, gagging in the process. Tears start streaming from her eyes and François adds to her excitement by pinching her nipples in response. They both look like they're thoroughly enjoying themselves.

I continue my oral gymnastics on Yvette's pussy as she sits heavily on my face. The more she gets aroused, the more she leans forward as if trying to suffocate me. Breathing gets difficult and an unknown feeling of blissful arousal comes over me as I feel myself slowly drifting away. I like it and remember she wants it rough. Are we really succeeding?

Feeling I'm on the verge of passing out, Yvette turns around to pull down my pants and underwear and starts fondling and sucking my cock as I regain my breath. She slows down momentarily to watch her husband as my girlfriend stops sucking his cock to put a condom in her mouth, going down on him with the condom between her lips and, without using her hands, rolls it down his shaft while his cock slides inside her throat. My girlfriend then changes position mounting François in reverse cowgirl taking his cock deep inside her and begins riding him. She leans forward on her elbows with her titties touching his legs and pressing down his cock away from his belly. He must enjoy the view of her firm ass moving back and forth, bouncing against his lower belly. François puts his hands on my girlfriend's hips and follows her movements.

I push his wife on all fours on the bench, smack her ass a couple of times, kneel down behind her and start eating her out while penetrating her butthole with my thumb. Her moaning increases so much I decide to roughly press her down on her belly with her face on the bench enabling her to muffle the sound. At this point she hands me a condom which I put on my eager cock. I smack her ass again. Yvette feels exceedingly wet as I penetrate her from behind. First I let my throbbing cock slide softly into her pussy, feeling her inside, letting her get the feel of me. Then I pull partly out and powerfully slam down as deep as possible, resting there but keeping up pressure. I think I might be reaching the limit of what she can handle but still on the safe side.

Yvette flinches and starts to moan a lot louder. I ask "stop?" assuming it has a similar meaning in French and she responds by pushing her big ass firmly backwards and reaching her arms behind her back grabbing my hips as if to pull me inside even deeper. Stopping is obviously the last thing on her mind now. She vehemently pulls and pushes on my hips clearly indicating a rhythm. I start fucking her in this rhythm bumping on her ass, with my balls bouncing against her clit, and feel her relax below me with an approving grunt. I enjoy making Yvette feel good, this is clearly what she wished for.

Keeping the rhythm I change between shallow moves to grind her most sensitive areas and thrusting hard and deep going for the areas around the cervix. Yvette rewards me with squirming and flinching in enjoyment below me. Will she need additional clitoral stimulation or could she climax from this alone, I wonder. She moves one hand down below her body so I expect her to start rubbing her clit but she reaches further, grabs my balls and starts squeezing and pulling them hard on every deep thrust to get me in even deeper. Her moaning gets louder, her panting heavier and with a muffled cry she reaches a throbbing pulsating climax that seems to last forever.

When she's done, Yvette turns around and snuggles against me, blissful and relaxed. She gives me a long french kiss and rests her head on my shoulder, still quietly panting. Since she seems perfectly happy, I decide to save my load for later. My girlfriend will no doubt want a hot and heavy night from me.

More people now appear sitting in their seats, as apparently a lot of the spectators have been engaging in their own horizontal out-of-sight activities to spice things up. The heavier moaning sounds I've been hearing did not all come from the movie and our contribution to them went by unnoticed.

My girlfriend rode François to his climax and we all are drained, dressed and decent when the movie reaches its happy ending.

Both Yvette and her husband are completely satisfied and in rapid French talking show their enthusiasm in sharing their experience. Yvette gives me a firm hug and embraces my girlfriend, who (kinky as always) kisses Yvette's husband full on the lips while stroking his crotch. François and I shake hands. We say our goodbyes an each go our own way.

I know this movie experience must have made my girlfriend extremely horny, tonight will be exhausting but fun.

Tomorrow our good friends Ann and Brenda will join us for a few days so more fun is waiting for all of us in the coming days. There's a nudist beach in the area and Ann may well bring her 'toolbox'.
