Excited and spent we all calmed down for awhile. Having done so we all had a glass of wine and chatted for a while. Penny still wearing stockings and ...uspenders and Rachel still with her big tits hung over her bra, looking flushed and beautiful in her sexy glasses. My cock which had never really lost an erection got seriously hard again. 'Look at Bob the dirty bugger' Penny said to Rachel 'sat there with that hunk of a cock he has stiff as a board'. Rachel asked 'when you were doing you know. Wax fell onto her boobs and she started screaming…Smitha and her gang started laughing loudlySmitha: she is very proud to be an honest beautiful lady and look now she is just a slaveSmitha then took a machine from the physics lab… It was a motor machine.. Smitha took a big dildo from her bag and fitted it to the machine. ..She then placed the dildo machine near my sister’s pussy and she switched it on….The speed was minimum… The dildo slowly started entering and exiting her pussy… Smitha. I had a strong opinion about it. The opinion was that no one would care what I thought.When the Plane landed. the Professor and her daughter were met by their interpreter and two Mexican Uniformed policemen. The cops would escort them to the hotel. The cops went with them to pick up their luggage. We tagged along to get our clothes and tooth brushes.A Mexican dress in casual clothes walked up to our little group. "Karl?" he asked. He didn't single anyone out. I was more than a little surprised. Ab wo moan kar rahi thi, jisse main aur horny ho gaya.Fir maine uski bra ko khola, aur uske boobs ko choosne laga. Uske nipple ek-dum hard ho gaye the, aur main unhe ache se choos raha tha. Ab wo bahut garam hone lagi. Main kabhi uske left boob ko, to kabhi right boob ko choosta. Maine uske dono boobs ko ache se choosa. Uske baad maine usko firse kiss kiya, aur wo jeans ke upar se mere lund ko sehla rahi thi.Fir main uski chut par hath ferne laga, to usne mana kar diya. Wo mujhe bolne.
