She sai... ok so we went to the field and said show me your boobs so she lifted her top up and took her bra off they looked great. I then started to feel them they felt great then I started to suck her nipples she was moaning while I was so hard in my boxers. She then said let's she your cock then so I got my cock out and she said is it that hard for me. I alone was standing all nude in front of the three boys , they came near me and were staring at my nude body.I was puzzled what to do for moment one of the boys caught hold of my vagina so tight with his hands that his nails pierced in my skin.

I asked my sister to lower her top a little more after we returned to the table so that they could see her nipples.I also told her that she would get fucked by all 4 of them if she did that. She said she would think about it, and we returned to the table. Sister and I took our places after we returned to the table. I told them what we discussed. Everyone was silent for 2 minutes.My sister whispered in my ears and asked me to pull her.
