Mr. Groves, one of the teachers who was chaperoning us, gave me a hard time about it but he backed off when I lied and told him I was having my period... All I had to do was start talking about how heavy the flow was and he couldn't get out of my room fast enough.That left me with almost the whole day—we weren't leaving for Venice until late afternoon. I sat around feeling sorry for myself, and almost got bored enough to go find my parents, and do something with them. Instead, I went for a walk.. I nibbled her earlobe, this time her hands squeezed.The music was finishing, very slowly she released her grip on me. I let my lips just touch to hers before we parted. Her eyes were staring into mine, a puzzled look on her face. Then Dawn was at our side, "You two make a lovely couple you know. You okay, Sylvia?"For a moment she hesitated, then she seemed to make her mind up, "Oh, yes, I'm fine, thank you." She surprised us all by giving first Dawn, then Dina and finally me, a big tight. Climbing on beside you , I leans in a begins to kiss your neck and nibble your ear a hand finds your breast cupping and caressing you softly your nipple between my fingers pulling on it slightly. Kissing my way down your body my lips find your other nipple using my tongue to lick around it before taking you between my lips, I hear your breathing deepen as I continue to suck and caress your nipples and breasts ,, pushing them together I start to lick and suck each nipple in turn ,, one hand now. She rolled me over and she came on top...she was literally jumping on my dick...It felt like heaven....I was enjoying the view....touching, rubbing and playing with both her tits while she put both her hands on my chest...I was going to explode again and I did while she was on me and thus shooting my load deep into her pussy...It was one of my best orgasms ever....I rolled her over again and we continued doggy style...There was no glimpse of my load on her pussy lips and so definitely my cum.
