Pussy.

We sat on the floor next to each other and loosened the zips to our jeans and unfastened the button to make it easier to access each other.

Simultaneously our hands reached for each other and as I rubbed Debbie's clit I felt my cock harden as she wrapped her fingers around it's shaft and gently wanked me.

Debbie's cunt started to moisten and I pushed my middle finger into the wet opening, reaching upwards towards her G-spot, which on hitting made her moan a little and start to wank my cock harder and faster.

We continued the mutual masturbation until our alloted 3 minutes were up and as I pulled my finger out of her pussy I raised my hand to my mouth and sucked the juices from my finger.
