Kissing my way up to my sister’s tits l sucked and gently bit her nipples at the same time guided my cock into Theresa pussy, she realised what was going to happen and said she wasn’t sure about going all the way because l was her brother, which l found a strange thing for my sister to say at that point and carried on sliding my whole shaft inside Theresa, when my balls pressed against her lower pussy l told her to relax then lifted her legs so l could get every inch of my shaft buried deep inside her wet sticky pussy hole. I kept my shaft firmly wedged between my sister’s pussy lips giving little thrusts as the last of my spunk dribbled from the urethral opening at the end of my cock, after we caught our breaths l kissed Theresa hard on the mouth, she forced her tongue into my mouth and l did the same to her, Theresa sucked my tongue which l found quite erotic.
