Cisco and James, both patients at the clinic, entered the exam room for their follow-up appointments. James needed a
booster shot, while Cisco was there to donate sperm for the current drive and earn some extra money. The Doctor agreed to
handle both procedures simultaneously. As the Doctor administered the booster shot, James had questions about its
composition and how it was made. The Doctor explained in detail, even using Cisco as an example by having him kneel to
demonstrate the process.

Both James and the doctor unfasten their pants as Cisco eagerly takes turns sucking on their cocks. While Cisco is
pleasuring James, he strokes the doctor's cock and vice versa. Cisco's skills at giving oral pleasure are exceptional and both
men are thoroughly enjoying his talented mouth.

Both James and the Doctor carefully lift Cisco onto the exam table where they both take turns fondling his throbbing cock.
The Doctor flips Cisco over, eager to taste his fresh, smooth hole. As the Doctor's tongue delves into Cisco's entrance, he
also continues to pleasure James's pulsing cock with his mouth. Meanwhile, the Doctor expertly licks and fingers Cisco's
hole, preparing it for what is to come.

With the necessary lubrication applied, the Doctor slides his penis into Cisco's tight opening while Cisco continues to
pleasure James orally. As the Doctor penetrates relentlessly, Cisco moans in ecstasy and James eagerly waits for his turn.
They switch positions, with James placing Cisco on his back and entering him deeply. The Doctor watches and strokes
himself, urging the two boys to relax and savor the experience.

The Doctor couldn't take it any longer and his erection was on the edge of release. With a loud groan, he released a burst of
semen onto Cisco's shoulder. The Doctor quickly scooped up his ejaculate, while James continued thrusting in and out of
Cisco's asshole. Both men were nearing climax, and the Doctor was eager for one of them to finish soon.

With a grunt, James withdraws from Cisco's body and ejaculates onto his lower stomach. The doctor quickly grabs a sample
cup to collect more sperm, but he realizes he needs more. Cisco eagerly obliges, stroking his own cock until he releases
another load of hot cum onto his stomach. The doctor collects this as well in the sample cup.

The Doctor extracts enough sperm from the patient to create the serum needed for the booster shot. After administering the
serum to James, Cisco receives his payment for being a sperm donor.
