" Jill grinned."Really?"Jill nodded. "Like you two there. If you were to kiss, It would be hot." Us?"She nodded, and then whispered something to my si...ter that got hergiggling."But we're straight!" John objected."That's kinda the point. Like you said, we'd want to join in, and becauseyou're straight, we'd be welcome." What would you give us?" John asked. "What would you give to watch uskiss?" John! You serious?" I stammered.My sister smiled at him, and said, "How about us? You kiss each other,. She was worn out. I felt my balls tightening. I hammered away at her even harder.“Don’t cum inside me though …………………..I’m ..not… on…the …pill” she was able to utter.“TOO late”, I said as my cum boiled up. I growled loudly and exploded into her. The hot cum splashing against her unprotected uterus making her cum again. Her cunt tightened its grip on my cock as she came and squeezed every last drop of baby juice into her womb. Exhausted, I lay on top of her till my cock softened and slipped. I held the passenger door of the little Ford open for her and was rewarded by another sight of Mom's glorious, fishnet-clad legs when she scooched down in the low seat."I didn't feel like changing...too much nervous energy, I guess." she said with a laugh in the car.I surprised myself by saying, "You should have kept the wig on too." And we both laughed.When we got back home, we entered the kitchen through the garage door and Mom said, "Let's have another glass of wine and talk. I'm sorry I was. So she asked me help her out for one week as a tutor and she will pay me for that. Since I was free I agreed,. On the 2nd day she asked me stay in her house as since due to work it was always late around. 12 in night. I said I can stay from tomorrow and I will bring my clothes too she agreed. By now I have started fantasizing having sex with her and I wanted this opportunity. From 3rd night I stayed in her house and my luck was so high since there were only 2 rooms in her house I slept with her.
