I saw my sister were cojieron

Hi I’m Peter’m 20, and I’ll tell something that touched me to see when I was 13 and my sister was 17.

Once she and I went to a party in a hall, she was wearing a pair of jeans tight (which incidentally highlighted buttocks) and a fitted bodice hombliguera type. My sister was always half a bitch to deny it. Well the joke is that we were at the party and about 3 guys like 20 years they ate at him, did not stop him buttocks and my sister if you noticed but such situations liked ,. Then one of the guys approached him to talk and then the other two, after a while talking 3 types left the place and went. My sister went to the bathroom and then said he was going to the store right now returned not to leave me there and left. I decided to follow without noticing when he left the room, she walked about three blocks to a dead guy, I saying that it was night and there was no people on the street, once he got out the 3 types and one went behind her and started kissing her neck, another began kissing on the mouth and the other one unbuttoned his pants, she brushed them three and took off her blouse and bra revealing her big boobs, just after he took off his pants and bringing running has completely naked. The types without take nothing took your piece and jumped on her back one popped it up the ass as she bent to suck at the I faced, and the other was sucking tits and lasted a while until they changed position and she lay on a car and opened her legs so one of the guys lick her vagina while she sucked dick to another. After which he was richly pounding the vagina and penetrated stopped right there and made it repeatedly. From where I was watching the moans of pleasure from my sister they heard. After penetrating one of the guys went and the other office and slipped through the vagina while the other penetrated by the quota, my sister burst of pleasure and the man did not stop to. In the end my sister bent and types are dripped on his face. After that the guys went and my brother dressed and return to the party as if nothing had happened.
