My hand finds your cock again and I push you back onto the bed and climb onto you. I rock my wet cunt over you, my juices lubricating you. "I'm going ...o fuck you." I smile, licking my lips. I reach around and unclasp my bra, you pull it from me and discard of it, moaning as your hands find my breasts, your fingers teasingly pinch my nipples and you reach up with your tongue, sucking my erect nipple into your hot mouth, sending shock waves of pleasure through me.Enough with the teasing. I want. I was pinned and could do nothing to help as she struggled to thrust her hips upwards and forwards to drive my cock in further.Her sister's wetness flowed down my ball sack as Twin 2 continued to stab herself on and over my cock. Her forward thrusts gently slapped the remainder of my shaft against her sister's exposed and erect clit. Each bump bought and increasing response from the twin sandwiched between us.I am not sure who started first but when one went we all did. Twin 1 withdrew from her. However, out of that rejection, I started to fantasise about women I knew spanking me. Those women were mainly younger than me, but then I was only in my early thirties. It never happened and as I got older so the women I fantasised about were my own age and then it moved to them being younger than me.So when I saw sixteen-year-old Lauren and heard her so-strict voice, it was easy to settle upon her. Of course, all the time I knew it wouldn’t happen, but then it was a fantasy that I used to. "Oh, please don't hurt me."She licked the forefingers and thumbs of both hands, then slipped them under the top and massaged her nipples. They instantly grew erect."Stop," she sighed. "Oh, no, don't bite them, don't bite."Then she jerked her hands behind her, as if someone were tying her wrists. She squirmed and struggled, fighting her invisible bonds.Her eyes widened in mock horror. She arched her back, pulling her pelvis away from an invisible assailant in front of her."Oh, no," she said.
