Susan.

"You should go next, babe," Deborah suggested.

"Are you sure?" Susan asked.

"Yeah," her wife nodded. "This is the last night of my ovulation so I want to make the best of it."

"Of course, honey!" Susan agreed.

My wife rolled off of me, with my erection slipping out of her warm depth, to let her friend take her place.

"Ready?" I asked Susan, offering my hand for support as she stood over me.

"Yes," she nodded and lowered herself down on my waiting cock. She bit her lower lip as my cock head slipped past her wet lips and stretched her tight cunt until she sat on my balls. She looked down at me and smiled. "I still can't believe I enjoy having a big cock in me..."

"It's great, isn't it, babe?" Deborah giggled and leaned in to give a kiss to her wife.

"Yeah," she moaned. "It's better than dildo."

"Thanks for the great compliment!" I chuckled.

"But I'm still a lesbian, remember?" she reminded me with a playful squeeze of my shaft with her pussy muscles. "We're just having sex to get me pregnant."

"Making love..." I corrected her before my wife could.

"I stand corrected -- making love to get me pregnant." With that she started bouncing up and down on my thick meat pole.

I moved my hands to her sides and held her hips as if to try to control her like a cowgirl would grasp the reins to avoid falling off a wild bronco. I stared at her petite breasts jiggling and moved my hands to cup them, expecting her to smack them away but instead she let out a soft moan when my thumbs flicked across her nipples.

Susan flailed her head from side to side, whipping her long hair around, as she started to climax. I could feel her pussy spasm around my cock as she came. Then she was still for a moment as her entire body was consumed by her orgasm. God, I wanted to cum there and then but her pussy was felt too good to end it there.

I thought she was done and Deborah would take over but she opened her eyes and glared at me. "I want you to cum in me, Michael, and put a baby in me!" she growled, pushing my hands away so she could rest her delicate hands on my chest for support as she started driving herself down violently on my shaft like a pile driver.

"Holy shit," I gasped, surprised at Susan's sudden change in demeanor.

"Cum in me!" she barked.

I wanted to hold off as long as possible but the vice-like grip of her cunt was too much. With a grunt, my vision went black for a moment as my cock spewed what felt like a gallon of semen into her hungry pussy. She stopped moving and savored the sensation of my throbbing shaft pumping my precious baby batter into her fertile womb. I let out groan when I felt her pussy squeezing my cock, trying to milk every drop of sperm from my balls.

"You did great, Michael," she smiled and leaned down to give me a unsuspecting kiss on the lips.

"Thanks..."

"Good," she giggled as she pushed herself off of me, "you're still hard for Deb!"

"I'm not going to pass up my last chance to knock her up!" I chuckled, looking over at Deborah, who was playing with her sodden snatch. "Ready?"
