Marina's cousins, Lisa and Robert, would be staying at her house for a full week. I thought this would be an end to our sex education tutoring, but I was very wrong. Marina instead told me that she had told her cousin Lisa everything about our little sessions, and that Lisa was interested in "being tutored" too. Robert would be another story, although Marina did want to see if he would go along with what we had planned. My plan was to have sex with both girls!
Marina and I decided a game of strip poker would do the trick. That way each of us would undress little by little and the embarrassment would be spread around. Marina and I fixed it so we would win the first two hands, so we could get things started. The way we played, whoever won the hand got to tell someone else at the table what piece of clothing to remove. When her cousins arrived we spent a little time getting to know each other, but when Marina's parents left for the night we got down to business.
I won the first hand, and told Marina to remove her jeans. She stood up next to where Robert was sitting and began to peel off her Levi's slowly, she knew exactly what to do. Robert watched intently and began to squirm in his seat, I'm sure he was getting an erection, I know I was. Marina's tiny little panties barely covered her tight ass, and her pussy hair was visible through the sheer material. When she sat down she let her hand fall to between her legs and she nonchalantly rubbed her inner thighs.
Marina dealt next and won the hand as we planned-she said "I'm not going to be the only girl undressing, Lisa take off your blouse." Lisa looked embarrassed but began to unbutton her blouse, when she opened it and took it from her shoulders, I could see that she had a beautiful pair of tits just like her cousin. Her nipples were already hard and ready to burst from her bra which pushed her breasts together and up.
Robert now was definitely in some discomfort because of what was happening in his pants, my cock was already hard and ready to be let loose. Robert dealt, and I won the next hand. "Robert you look a little uncomfortable, why don't you take off your pants" I told him. He got to his feet and turned his back to the table, letting his pants fall to the floor. When he sat down it was obvious his cock was large and already hard as a rock.
Both girls stared at his crotch. Next hand went to Robert, who didn't want to be alone so he told me to remove my jeans. I gladly stood up proudly and undid my belt, I faced Lisa and pulled my zipper down, when I pulled down my pants I "accidentally" caught my underwear and pulled them down halfway, giving Lisa a good look at my throbbing hard-on. She smiled when she saw it and looked me in the eye when she giggled "can't you control that thing?"
The hands continued-Marina, Lisa, Robert, and me losing our clothes until we all sat in nothing but our underwear. That's when Marina and I explained how the game would end. When only one of us was left with our underwear on the winner of the hand would have a decision to make. The game could come to an end, by having that person remove their last piece of clothing, or the winner could tell anyone at the table to do anything, short of intercourse, to any other person at the table.
Lisa lost her panties first, her cunt had a patch of soft brown hair around the lips, her outer lips pouted. Robert was next, he seemed relieved to be able to let his cock spring free, it was about 7 inches long and looked ready to pop, then my lovely Marina lost her panties, her pussy lips were already wet and she let a finger disappear inside her cunt while I dealt the next hand. Excellent! I won the hand and since I was the only one left wearing anything I wasn't about to make myself strip.
